Region Beta Paradox Quotes

Norepinephrine: The Wake-Up Neurotransmitter One of norepinephrine’s effects on the brain is to sharpen attention. As we saw earlier, norepinephrine (aka noradrenaline) can function as both a neurotransmitter and a hormone. When we perceive stress and activate the fight-or-flight response, the brain produces bursts of norepinephrine, triggering anxiety. But sustained and moderate secretion can also produce a beneficial result in the form of heightened attention, even euphoria, and meditation has been shown to produce a rise in norepinephrine in the brain. A modest dose of norepinephrine is also associated with reduced beta brain waves. 5.11. Norepinephrine: your wake-up molecule. Notice the paradox here. Norepinephrine is associated with both anxiety and attentiveness. How do you get enough to be alert, but not so much you’re stressed? Surrender is the key. Steven Kotler, co-author of Stealing Fire, says that stress neurochemicals like norepinephrine actually prime the brain for flow states. At first, the meditator is frustrated by Monkey Mind. But if she surrenders, despite the perpetual self-chatter of the DMN, she enters the next phase of flow, which is focus. She has hacked her biology, using the negative experience of mind wandering as a springboard to flow. Norepinephrine’s molecular structure is similar to its cousin, epinephrine. While epinephrine works on a number of sites in the body, norepinephrine works exclusively on the arteries. When both dopamine and norepinephrine are present in the brain at the same time, they amplify focus. Attention becomes sharp, while perception is enhanced. Staying alert is a key function of the brain’s attention circuit, which keeps you focused on the object of your meditation and counteracts the wandering mind. It also stops you from becoming drowsy, an occupational hazard for meditators. That’s because pleasure neurotransmitters such as serotonin and melatonin (for which serotonin is the precursor) can put you to sleep if not balanced by alertness-producing norepinephrine. Again, the ratios are the key. Oxytocin: The Hug Drug 5.12. Oxytocin: your cuddle molecule. Oxytocin is produced by the hypothalamus, part of the brain’s limbic system. When activated, neurons in the hypothalamus stimulate the pituitary gland to release oxytocin into the bloodstream. So even though oxytocin is produced in the brain, it has effects on the body as well, giving it the status of a hormone. It is one of a group of small protein molecules called neuropeptides. A closely related neuropeptide is vasopressin. All mammals produce some variant of these neuropeptides. Oxytocin promotes bonding between humans. It is responsible for maternal feelings and physically prepares the female body for childbirth and nursing. It is generated through physical touch but also by emotional intimacy. Oxytocin also facilitates generosity and trust within a group. Oxytocin is the hormone associated with the long slow waves of delta. A researcher hooking subjects up to an EEG found that touch stimulated greater amounts of delta, with certain regions of the skin being more sensitive. The biggest effect was produced by tapping the cheek, as we do in EFT. It produced an 800% spike in delta.
