Olfactory Sense Quotes

The fragrance of white tea is the feeling of existing in the mists that float over waters; the scent of peony is the scent of the absence of negativity: a lack of confusion, doubt, and darkness; to smell a rose is to teach your soul to skip; a nut and a wood together is a walk over fallen Autumn leaves; the touch of jasmine is a night's dream under the nomad's moon.

Are You Ready for New Urban Fragrances? Yeah, I guess I'm ready, but listen: Perfume is a disguise. Since the middle ages, we have worn masks of fruit and flowers in order to conceal from ourselves the meaty essence of our humanity. We appreciate the sexual attractant of the rose, the ripeness of the orange, more than we honor our own ripe carnality. Now today we want to perfume our cities, as well; to replace their stinging fumes of disturbed fossils' sleep with the scent of gardens and orchards. Yet, humans are not bees any more than they are blossoms. If we must pull an olfactory hood over our urban environment, let it be of a different nature. I want to travel on a train that smells like snowflakes. I want to sip in cafes that smell like comets. Under the pressure of my step, I want the streets to emit the precise odor of a diamond necklace. I want the newspapers I read to smell like the violins left in pawnshops by weeping hobos on Christmas Eve. I want to carry luggage that reeks of the neurons in Einstein's brain. I want a city's gases to smell like the golden belly hairs of the gods. And when I gaze at a televised picture of the moon, I want to detect, from a distance of 239,000 miles, the aroma of fresh mozzarella.

Scent is such a powerful tool of attraction, that if a woman has this tool perfectly tuned, she needs no other. I will forgive her a large nose, a cleft lip, even crossed-eyes; and I’ll bathe in the jouissance of her intoxicating odour.

Sometimes a scent is more evocative than a photo or an image. It is a primer for the deflagration of sensation, emotions, desires, uncontrollable atmospheres, dejavus that flood and wrap us like honey, until they make us drown in an unrepeatable moment of wellbeing... olfactory hallucinations that lead us anywhere: to the North of any South, to the East of any West...

You see, nothing is more immediate, more complete than the sense of smell. In an instant, it has the power to transport you. Your olfactory sense connects not to the memory itself, but to the emotion you felt when that memory was made. To recreate a scent memory is one of the most challenging, eloquent pursuits possible. It’s poetry, in its most immediate form.

Legend claimed Berserkers could move with such speed that they seemed invisible to the human eye until the moment they attacked. They possessed unnatural senses: the olfactory acuity of a wolf, the auditory sensitivity of a bat, the strength of twenty men, the penetrating eyesight of an eagle. The Berserkers had once been the most fearless and feared warriors ever to walk Scotland nearly seven hundred years ago. They had been Odin's elite Viking army. Legend claimed they could assume the shape of a wolf or a bear as easily as the shape of a man. And they were marked by a common feature-unholy blue eyes that glowed like banked coals.

I’d loved women who were old and who were young; those extra kilos and large rumps, and others so thin there was barely even skin to pinch, and every time I held them, I worried I would snap them in two. But for all of these: where they had merited my love was in their delicious smell. Scent is such a powerful tool of attraction, that if a woman has this tool perfectly tuned, she needs no other. I will forgive her a large nose, a cleft lip, even crossed-eyes; and I’ll bathe in the jouissance of her intoxicating odour.

Smell was our first sense, and it was so successful that in time the small lump of olfactory tissue atop the nerve cord grew into a brain. Our cerebral hemispheres were originally buds from our olfactory stalks. We think because we smelled.

The cent you desire is hidden in the scent of a flower.

The spiraling flights of moths appear haphazard only because of the mechanisms of olfactory tracking are so different from our own. Using binocular vision, we judge the location of an object by comparing the images from two eyes and tracking directly toward the stimulus. But for species relying on the sense of smell, the organism compares points in space, moves in the direction of the greater concentration, then compares two more points successively, moving in zigzags toward the source. Using olfactory navigation the moth detects currents of scent in the air and, by small increments, discovers how to move upstream.

Masters: Situation appears dire. Look around. Do you see any adults? Me: My ball size indicates I’m the adultest thing here. Me: I haven’t been rejected this hard since I tried to block the punt in that game against OSU last semester. Masters: My wife says rejection is good for you. Makes you mentally tough. Me: You love saying that phrase “my wife.” Masters: You bet your fat ass I do. Me: You don’t think it’s completely strange that you’re 21 and acting like a Taylor Swift song? Masters: Bro, sorry you feel left out. Stop by later and I’ll give you a hug. Me: Fuck off. Masters: I have MY WIFE to do that for me. Thanks, though. Hug still stands. I’ll even let you smell me. MY WIFE says I smell delicious. Me: I’ve smelled you before, which is why I’m not sure how you convinced Ellie to marry you. She must have defective olfactory senses. Masters: Me and MY defective WIFE will be getting it on tonight. While u have only Rosie Palm. Me: Don’t worry. I get plenty of variety. Left-hand Laura sometimes steps in. Masters: Heard you were out with Josie Weeks. Be careful. She eats little linebackers like you for breakfast. And the fact that I don’t even want to make a sexually charged comeback tells me exactly how I feel about Josie. Hope she doesn’t mind being just study partners.

And if, as all philosophers on the subject have noted, art is a human activity that relies on the senses to reach the soul, did it not also stand to reason that dogs -- at least dogs of Mr. Bones' caliber -- would have it in them to feel a similar aesthetic impulse? Would they not, in other words, be able to appreciate art? As far as Willy knew, no one had ever thought of this before. Did that make him the first man in recorded history to believe such a thing was possible? No matter. It was an idea whose time had come. If dogs were beyond the pull of oil paintings and string quartets, who was to say they wouldn't respond to an art based on the sense of smell? Why not an olfactory art? Why not an art for dogs that dealt with the world as dogs knew it?

What may be featureless to us, a waste of undifferentiated ocean, is for them rich with distinction and variety, a fissured and wrinkled landscape, dense in patches, thin in others, a rolling olfactory prairie of the desired and the desirable, mottled and unreliable, speckled with life, streaky with pleasures and dangers, marbled and flecked, its riches often hidden and always mobile, but filled with places that are pregnant with life and possibility.

Possibly the most compelling reason for use of the expressive arts in trauma work is the sensory nature of the arts themselves; their qualities involve visual, tactile, olfactory, auditory, vestibular, and proprioceptive experiences.

Our olfactory bulbs have gathered endless sense patterns of foods high in sugar, fat and salt. These flavour memories have become part of the fabric of our sense of self and are not easily discarded, because the system, as we have seen, is designed ‘not to forget’.

The sight of my mother's handwriting on the slips of paper and in the margins of the book causes me to inhale sharply, and for a moment I smell licorice, as if the mere sight of her heavily styled penmanship has produced an olfactory hallucination. It's a delicate smell, more like anise or fresh tarragon than the sugary smell of a licorice pastille. Smell, I remember my mother once telling me, is the most powerful of the senses. Without it, there is no taste. Long ago I lost the memory of her face, the sound of her voice, the touch of her fingers. But I can still remember her smell, in the aroma of a sherry reduction, the perfume, delicate and faint, that lingers on your hands after you've run them through a hedge of rosemary, the pungent assault of a Gauloises cigarette. Any of a thousand smells are enough to conjure her memory.

An infant’s scent seems to flip certain neural switches in the parents. The mother’s sense of smell gets completely rewired during pregnancy, so that the scent of her own infant becomes incredibly alluring. In the meantime, though, because the olfactory infrastructure is being overhauled, other wonderful aromas may smell disgusting. When

Scientists still know very little about how the olfactory cortex in the brain converts impulses from receptors into conscious senses of smell. But Harry wasn’t thinking so much about the hows, he just knew that when he smelled her, all sorts of things started happening in his head and body. Like his eyelids closing halfway, like his mouth spreading into a broad grin and his mood soaring.

smell is the only sense that goes straight to the brain’s cortex—the olfactory nerve is close to the part of the brain that deals with emotions and memory, which is why the smell of food evokes nostalgia and memories, and also why no Michelin star chef can compete with your grandmother’s dal. After all, it is not objective taste and aroma that matters but the fond memories associated with it that come rushing back when you eat a good home-cooked dal.

Sound waves, regardless of their frequency or intensity, can only be detected by the Mole Fly’s acute sense of smell—it is a little known fact that the Mole Fly’s auditory receptors do not, in fact, have a corresponding center in the brain designated for the purposes of processing sensory stimuli and so, these stimuli, instead of being siphoned out as noise, bypass the filters to be translated, oddly enough, by the part of the brain that processes smell. Consequently, the Mole Fly’s brain, in its inevitable confusion, understands sound as an aroma, rendering the boundary line between the auditory and olfactory sense indistinguishable. Sounds, thus, come in a variety of scents with an intensity proportional to its frequency. Sounds of shorter wavelength, for example, are particularly pungent. What results is a species of creature that cannot conceptualize the possibility that sound and smell are separate entities, despite its ability to discriminate between the exactitudes of pitch, timbre, tone, scent, and flavor to an alarming degree of precision. Yet, despite this ability to hyper-analyze, they lack the cognitive skill to laterally link successions of either sound or smell into a meaningful context, resulting in the equivalent of a data overflow. And this may be the most defining element of the Mole Fly’s behavior: a blatant disregard for the context of perception, in favor of analyzing those remote and diminutive properties that distinguish one element from another. While sensory continuity seems logical to their visual perception, as things are subject to change from moment-to-moment, such is not the case with their olfactory sense, as delays in sensing new smells are granted a degree of normality by the brain. Thus, the Mole Fly’s olfactory-auditory complex seems to be deprived of the sensory continuity otherwise afforded in the auditory senses of other species. And so, instead of sensing aromas and sounds continuously over a period of time—for example, instead of sensing them 24-30 times per second, as would be the case with their visual perception—they tend to process changes in sound and smell much more slowly, thereby preventing them from effectively plotting the variations thereof into an array or any kind of meaningful framework that would allow the information provided by their olfactory and auditory stimuli to be lasting in their usefulness. The Mole flies, themselves, being the structurally-obsessed and compulsive creatures that they are, in all their habitual collecting, organizing, and re-organizing of found objects into mammoth installations of optimal functional value, are remarkably easy to control, especially as they are given to a rather false and arbitrary sense of hierarchy, ascribing positions—that are otherwise trivial, yet necessarily mundane if only to obscure their true purpose—with an unfathomable amount of honor, to the logical extreme that the few chosen to serve in their most esteemed ranks are imbued with a kind of obligatory arrogance that begins in the pupal stages and extends indefinitely, as they are further nurtured well into adulthood by a society that infuses its heroes of middle management with an immeasurable sense of importance—a kind of celebrity status recognized by the masses as a living embodiment of their ideals. And yet, despite this culture of celebrity worship and vicarious living, all whims and impulses fall subservient, dropping humbly to the knees—yes, Mole Flies do, in fact, have knees!—before the grace of the merciful Queen, who is, in actuality, just a puppet dictator installed by the Melic papacy, using an old recycled Damsel fly-fishing lure. The dummy is crude, but convincing, as the Mole flies treat it as they would their true-born queen.

smell is often referred to as the invisible sense: we regularly experience it without consciously registering it. A smell enters our nose, travels to our olfactory bulb, and makes its way directly to our hippocampus, our amygdala (an emotionprocessing center), and our olfactory cortex (which not only deals with smells but is involved in complex memory, learning, and decision-making tasks), triggering a host of thoughts, feelings, and recollections—yet more likely than not, we note neither smell nor memory.

Moving on, while he wondered, the dark through which Mr. Lecky's light cut grew more beautiful with scents. Particles of solid matter so minute, gases so subtle, that they filtered through stopping and sealing, hung on the unstirred air. Drawn in with Mr. Lecky's breath came impalpable dews cooked out of disintegrating coal. Distilled, chemically split and reformed, they ended in flawless simulation of the aromas of gums, the scent of woods and the world's flowers. The chemists who made them could do more than that. Loose on the gloom were perfumes of flowers which might possibly have bloomed but never had, and the strong-smelling saps of trees either lost or not yet evolved. Mixed in the mucus of the pituitary membrane, these volatile essences meant more than synthetic chemistry to Mr. Lecky. Their microscopic slime coated the bushed-out ends of the olfactory nerve; their presence was signaled to the anterior of the brain's temporal lobe. At once, thought waited on them, tossing down from the great storehouse of old images, neglected ideas - sandalwood and roses, musk and lavender. Mr. Lecky stood still, wrung by pangs as insistent and unanswerable as hunger. He was prodded by the unrest of things desired, not had; the surfeit of things had, not desired. More than anything he could see, or words, or sounds, these odors made him stupidly aware of the past. Unable to remember it, whence he was, or where he had previously been, all that was sweet, impermanent and gone came back not spoiled by too much truth or exact memory. Volatile as the perfumes, the past stirred him with longing for what was not - the only beloved beauty which you will have to see but which you may not keep. Mr. Lecky's beam of light went through glass top and side of a counter, displayed bottles of colored liquid - straw, amber, topaz - threw shadows behind their diverse shapes. He had no use for perfume. All the distraction, all the sense of loss and implausible sweetness which he felt was in memory of women. Behind the counter, Mr. Lecky, curious, took out bottles, sniffed them, examined their elaborately varied forms - transparent squares, triangles, cones, flattened ovals. Some were opaque, jet or blue, rough with embedded metals in intricate design. This great and needless decoration of the flasks which contained it was one strange way to express the inexpressible. Another way was tried in the names put on the bottles. Here words ran the suggestive or symbolic gamut of idealized passion, or festive night, of desired caresses, or of abstractions of the painful allure yet farther fetched. Not even in the hopeful, miracle-raving fancy of those who used the perfumes could a bottle of liquid have any actual magic. Since the buyers at the counters must be human beings, nine of every ten were beyond this or other help. Women, young, but unlovely and unloved, women, whatever they had been, now at the end of it and ruined by years or thickened to caricature by fat, ought to be the ones called to mind by perfume. But they were not. Mr. Lecky held the bottle in his hand a long while, aware of the tenth woman.

So trees communicate by means of olfactory, visual, and electrical signals. (The electrical signals travel via a from of nerve cell at the tips of the roots.) What about sounds? Let's get back to hearing and speech. When I said at the beginning of this chapter that trees are definitely silent, the latest scientific research casts doubt even on this statement. Along with colleagues from Bristol and Florence, Dr. Monica Gagliano from the University of Western Australia has, quite literally, had her ear to the ground. It's not practical to study trees in the laboratory; therefore, researchers substitute grain seedlings because they are easier to handle. They started listening, and it didn't take them long to discover that their measuring apparatus was registering roots crackling quietly at a frequency of 220 hertz. Crackling roots? That doesn't necessarily mean anything. After all, even dead wood crackles when it's burned in a stove. But the noised discovered in the laboratory caused the researchers to sit up and pay attention. For the roots of seedlings not directly involved in the experiment reacted. Whenever the seedlings' roots were exposed to a cracking at 220 hertz, they oriented their tips in that direction. That means the grasses were registering this frequency, so it makes sense to say they "heard" it.

On the other hand, everyday language would soon prove inadequate for designating all the olfactory notions that he had accumulated within himself. Soon he was no longer smelling mere wood, but kinds of wood: maple-wood, oak-wood, pine-wood, elm-wood, pear-wood, old, young, rotting, mouldering, mossy wood, down to single logs, chips and splinters – and could clearly differentiate them as objects in a way that other people could not have done by sight. It was the same with other things. For instance, the white drink that Madame Gaillard served her wards each day, why should it be designated uniformly as milk, when to Grenouille’s senses it smelled and tasted completely different every morning depending on how warm it was, which cow it had come from, what that cow had been eating, how much cream had been left in it and so on … Or why should smoke possess only the name ‘smoke’, when from minute to minute, second to second, the amalgam of hundreds of odours mixed iridescently into ever new and changing unities as the smoke rose from the fire … or why should earth, landscape, air – each filled at every step and every breath with yet another odour and thus animated with another identity – still be designated by just those three coarse words. All these grotesque incongruities between the richness of the world perceivable by smell and the poverty of language were enough for the lad Grenouille to doubt that language made any sense at all; and he grew accustomed to using such words only when his contact with others made it absolutely necessary.

I could see into the shadows, where the very blades of grass and the leaves and buds of plants were sharply defined though it was a dark night. I was acutely aware of my ears, hot, pulsing, and humming. Now fragrance took command, and I was struck with the scents of the evening. Unable to resist, I rolled on the ground, breathing in the wet tang of dewy grass and the musk of the mud in which it grew. I glided my muzzle through the blades, letting each soft edge tickle my nose. When I lifted it, I caught the delicate fragrance of wildflowers and the powdery sweetness of red clover. The aromas permeated my body as if I could smell with my eyes, my toes, and my tail. I detected the essence of living fowl on the feathers of a fallen bird, but was quickly distracted by the blood-warm effluvia of rabbits and voles wafting up from a small hole in the ground. The air carried the scent of wet leaves after a forest rain. My senses were torn in two, with one thing calling my attention into the air and another, even more compelling, back down to the earth. The miasma of fetid earth, God's creatures, and the aromatic night air swirled in my head and through my body, competing with a cacophony of noises that grew louder and louder. The muffled sound of my paws as they made contact with the ground resonated in my ears. I felt in my body the vibration of all things touching the earth- animals small and large, as they interacted with the same soil that I was treading. The rustle of leaves in the trees, the screech of the wind blowing the hairs on my face, the fluttering of bees' wings, the distant cry of an owl- I heard each as a distinct, sharp sound. My senses were in control of my body. I was a living machine that processed sights, smells, and sounds.

A recent (and provocative) study in Science showed that men who simply sniffed negative-emotion-related odorless tears obtained from women showed reduced levels of testosterone and reductions in sexual arousal. So subtle olfactory signals could potentially affect many aspects of our psyche.

Why is coffee so valuable? isn't there other stuff in the, uh, multiverse, to find?"                 "Like what? Gold? There was enough gold and silver in the asteroid belt of your former solar system to make every house, car, building and road on Earth out of the stuff. Diamonds? shiny pebbles. Fiat currency? don't make me laugh. Utility is what creates value for the meta-traveler. Food, meta-vehicles, water, or at least whatever fluid solvent is necessary for continuing your biochemical reactions. Of these, the scarcest is good coffee. It rarely evolves, and only naturally evolved coffee has the right flavor. Only coffee grown in its native environment will please the palate. Few universes have the right cosmological constants and physical laws to even create good coffee. Good coffee only grows in narrow bands of subtropical climates and only at high elevations that aren't cold. Coffee is portable, dividable, consistent in mass, and quality can be tested with common olfactory senses. Every brew is a little different; the permutations of the coffee experience are endless. For most meta-traveling humanoid species, coffee is consistently satisfying. It is the only true currency."   *

The cooking oil they use sets off our olfactory senses designed to seek out foods with high fat. We’re programmed to be addicted. Add in salt and the fructose in ketchup, and it’s the perfect food—if you’re a Neolithic caveman getting all his other nutrients by eating gallbladders and animal intestines.

We humans are part of a lineage that has traded smell for sight. We now rely on vision more than on smell, and this is reflected in our genome. In this trade-off, our sense of smell was deemphasized, and many of our olfactory genes became functionless.

Our sense of scent has a limited vocabulary. Across known languages, anthropologists have found fewer words for our olfactory experience than any other sensation. So, we speak of our olfactory experience in similes and metaphors. We reach for language to describe smells in relation to our other senses. Bright, green, metallic, smoky, floral, fecal, loud, round, sharp, or citrus are words I might use, but these notes can be traced to objects, not the odors themselves. My favorite perfumes are slightly addictive, like the feeling of devouring a book. Perfume language is purple, its prose comfortable for me, it’s as if I revert to sensory language when I forget the performance of writing for a society (a country? a culture?) that loves a bare, spare sentence. I’ve been a devotee of purple anything since childhood: clothes, lipstick—a sentence. I admit that when I write in perfumed language, I feel truer as a writer, wilder and messier, anachronistic or mystic, I feel more embodied, when I write the physical materials I work with, encapsulating a story inside of a vessel. I perfume with materials distilled from the earth, but also aroma chemicals extracted from fossil fuels. This leaves me with more questions than answers, but perhaps that’s how we know there is a future, when we continue seeking answers to eternal questions: What is real, what is false? What is natural, what is artificial? What is necessary, what must be thrown away?

Receptor neurons bundle together into cables called axons, feeding up through holes in a perforated bone just behind the eyeballs called the cribriform plate. (In a serious head injury, the skull can shift, and the lateral movement of the cribriform plate shears those axons like a knife through spaghetti. Snip! No more sense of smell.) Once through the plate, the axons connect to two projections from the brain called the olfactory bulbs. There, in blobs of neurons called glomeruli, is where the bulk of the computation gets done. Mice, known for their acute sense of smell, have just about 1,800 glomeruli—but 1,000 genes that code for olfactory receptors. That’s a lot of perceivable smells. Humans have a seemingly pathetic 370 genes for receptors, but we have 5,500 glomeruli per bulb. That’s a lot of processing power. It must be doing something. The part of the brain that integrates all this information, the olfactory cortex, also gets inputs from the limbic region and other areas that deal with emotion—the amygdala and hypothalamus, among others. Processing of smells in the brain, then, is tied to not only the chemical perception of a molecule but also how we feel about it, and how we feel in general. Every other sense in the body is, in a way, indirect. In vision, light impinges on the retina, a sheet of cells at the back of the eye that makes pigments and connects to the optic nerve. In hearing, sound (which is really just waves of changing air pressure) pushes the eardrum in and out at particular frequencies, which translate via a series of tiny bones to nerves. Touch and taste are the same. Some cell, built to do the hard work of reception, gets between the stimulus and the nerves that lead to the brain for processing. Some physical effect—air pressure, reflected photons, whatever—gets between the stimulus and the perception. It’s all a first-order derivative. Not smell, though. When we smell something, we are smelling tiny pieces of that thing that have broken off, wafted through the air, and then touched actual neurons wired to actual pieces of brain. Olfaction is direct, with nothing between the thing we’re smelling, the smell it has, and how we perceive that smell. It is our most intimate sense.

When you inhale, you create a single airstream that allows you to both smell and breathe. But when a dog sniffs, structures within its nose split that airstream in two. Most of the air heads down into the lungs, but a smaller tributary, which is for smell and smell alone, zooms to the back of the snout. There it enters a labyrinth of thin, bony walls that are plastered with a sticky sheet called the olfactory epithelium. This is where smells are first detected.

As soon as they’d arrived, the odors of fertilizer and manure had overwhelmed him. They were staggering, almost intolerable, clouding his olfactory sense just when he really needed it. He leaned back against a fence post and pressed his hands against his temples, breathing through his mouth. His superior sense of smell made him part bloodhound, part pointer, and part bulldog. But sometimes, it just made him sick.

Odorant receptors can also vary from one individual to another in dramatic ways. For example, the OR7D4 gene creates a receptor that responds to androstenone, the chemical behind the stench of sweaty socks and body odor. To most people, it’s repulsive. But to a lucky few who inherit a slightly different version of OR7D4, androstenone smells like vanilla. That’s just one receptor out of hundreds, and all exist in varied forms, bestowing every individual with their own subtly personalized Umwelt. Everyone likely smells the world in a slightly different way. And if it’s that hard to appreciate the olfactory Umwelt of another human, imagine how hard the task becomes for another species.

SMELL: Creating a Soothing Olfactory Environment Your sense of smell can be a double-edged sword, as it can either overwhelm you or provide a source of joy. If you’re sensitive to smells, try eliminating toxins and chemicals from your living space to reduce discomfort and minimize migraine triggers. If you live with others, feel free to mention how smells affect you and see if everyone is on board with sensory-friendly options.

Human beings have one of the poorest senses of smell of all the organisms on Earth, so weak that we have only a tiny vocabulary to express it...We depend on the sophistication of trained dogs to lead us through the olfactory world, tracking individual people, detecting even the slightest trace of explosives and other dangerous chemicals.

And the largest piece was buried beneath a pile of offal Ziller had gathered along the bridle paths of Central Park. Naturally, as the days wore on, the exhibition began to engage senses other than sight and touch, offering somewhat of a challenge to olfactory aesthetics.

The olfactory stem cells replenish constantly even in a healthy nose. They are some of the only neurons in the human body with the ability to regenerate from scratch. And they do so constantly, growing like the perennial flowers in my mother’s garden but on warp speed.

It is possible that the olfactory neurons die and regrow because they are exposed so intensely to the environment, he explained. These are the only cranial nerve cells that actually make contact with physical stimulus directly from the outer world, interacting directly with odor molecules on each inhale. They aren’t in the possession of that buffer of skin.

Our hundreds of useless olfactory genes are left over from mammal ancestors who relied more heavily on the sense of smell to survive ... Our genes are similar to primates’, less similar to other mammals’, less similar still to reptiles’, amphibians’, fishes’, and so on.

Communication between trees and insects doesn't have to be all about defense and illness. Thanks to your sense of smell, you've probably picked up on many feel-good messages exchanged between these distinctly different life-forms. I am referring to the pleasantly perfumed invitations sent out by tree blossoms. Blossoms do not release scent at random or to please us. Fruit trees, willows, and chestnuts use their olfactory missives to draw attention to themselves and invite passing bees to sate themselves. Sweet nectar, a sugar-rich liquid, is the reward the insects get in exchange for the incidental dusting they receive while they visit. The form and color of blossoms are signals, as well. They act somewhat like a billboard that stands out against the general green of the tree canopy and points the way to a snack.

The theory is that with the emergence of full color vision we lost the need for detecting the world so keenly with our sense of smell, and there was essentially an exchange in importance between these two senses in primate evolution. The better you can see, the less acutely you need to smell. Animals, including humans, either have excellent color vision or an excellent sense of smell, but not both. The finite size of the human brain is to blame. The human brain is limited to between 1,300 and 1,400 grams in weight. Having a highly complex sense of both smell and vision would take up too much brain space and so these functions had to compete with each other for which had the better survival value. It seems superior visual detection was better for our ancestors’ survival than superior olfactory acuity, and the advantages offset the limitation to our sense of smell; hence, the large proportion of pseudogenes in our olfactory code.

For humans to be able to smell a chemical, it must be of low molecular weight,* volatile, and able to repel water, so that it can stick to our olfactory receptors.

Your olfactory sense connects not to the memory itself but to the emotion you felt when that memory was made. It could be argued that all perfume is born out of shame, a self-consciousness of our natural odor. We want to hide it.

In the humanities and social sciences, any research on odours comes up against four preconceived notions, all the more robust as they are considered interdependent: that Homo sapiens is, from a functional perspective, a microsmatic species; that we make little use of our sense of smell, considered the lowliest of the senses; that the consequence of this is that we live in societies evolving towards “olfactory silence”, and, lastly, that a defining characteristic of natural language on odours is its paucity." - Foreword by JOËL CANDAU

A simple character people are like a fragrant rose: they smell from far. One does not need, to test them, but can perceive them by the olfactory sense

Registering different flavours is one of the main ways that our bodies interact with the world around us. Amazingly enough, the human olfactory bulb is the only part of the central nervous system that is directly exposed to our environment, through the nasal cavity. Our other senses - sight, sound and touch - need to travel on a complicated journey via nerves along the spinal cord up to the brain. Smell and flavour, by contrast, surge direct from plate to nose.

Roger Peters told me once that wolves in the Superior National Forest defecate sometimes on beer cans. Like any scent mark, these scats give off both visual and olfactory signals. We should see more here than what the wolf might be telling us about our littering habits. The animals may be marking things they consider dangerous to other wolves, especially pups, for wolves also mark traps and poisoned baits by defecating on them. If Peters is correct in thinking that the olfactory information in a scat is intended for other pack members, the idea makes even better sense.

The Science of Scent The human sense of smell is about ten thousand times more powerful than other senses, and scent travels to the brain so rapidly that the mental or physical response to the fragrance an essential oil emits can be immediate. When you inhale an essential oil, its scent travels first through olfactory nerve cells inside the nose and into the larger olfactory system. The olfactory system then delivers the aroma to the olfactory bulb located inside the brain’s limbic system, which serves as the seat of emotions and the originator of emotional behavior. Depending upon which essential oil you are inhaling, you may feel a rapid release of mental strain or negative emotions, and you may feel muscle tension ease at the same time. You may feel more alert, excited, or engaged with your surroundings, and if the scent you are inhaling is a familiar one, you may rapidly access your collective unconscious and experience strong memories, particularly when those memories are closely associated with deeply emotional feelings.

A simple character people are like a fragrant rose: they smell from far. One does not need to test them but can perceive them by the olfactory sense.

olfactory senses,

Human beings are “so egocentric they won’t change otherwise. They haven’t. They’ve got this ego thing that they like to hold on to and they get really threatened . . .” At the same time there are “precious” things about human beings. “They can smell flowers, for instance. And that’s like so incredible, and they get to feel the sun on their skin.” As an alien being “I was operating out of less physicality, so you’re lighter at one level . . . There are certain advantages. One is you don’t get into these things like depression. But on the other hand it’s a little disjointed and a little bit removed . . . The olfactory sense is not there the same way. You don’t get the depth of smell, for instance,” she observed. At the same time the aliens have seen “a bigger picture,” and have more insight and patience. Also, “You have this thing in your head that [enables you] to access any kind of information telepathically. So you have this kind of informational pliability.
