A Certain Scientific Accelerator Quotes

It turns out that thousands of new hippocampus cells are born naturally each day, but most die soon afterward. However, it was shown that rats that learned new skills retained more of their new cells. A combination of exercise and mood-elevating chemicals can also boost the survival rate of new hippocampus cells. It turns out that stress, on the contrary, accelerates the death of new neurons. In 2007, a breakthrough occurred when scientists in Wisconsin and Japan were able to take ordinary human skin cells, reprogram their genes, and turn them into stem cells. The hope is that these stem cells, either found naturally or converted using genetic engineering, can one day be injected into the brains of Alzheimer’s patients to replace dying cells. (These new brain cells, because they do not yet have the proper connections, would not be integrated into the brain’s neural architecture. This means that a person would have to relearn certain skills to incorporate these fresh new neurons.)

Ultimately, one goal of this research is to create a “smart pill” that could boost concentration, improve memory, and maybe increase our intelligence. Pharmaceutical companies have experimented with several drugs, such as MEM 1003 and MEM 1414, that do seem to enhance mental function. Scientists have found that in animal studies, long-term memories are made possible by the interaction of enzymes and genes. Learning takes place when certain neural pathways are reinforced as specific genes are activated, such as the CREB gene, which in turn emits a corresponding protein. Basically, the more CREB proteins circulating in the brain, the faster long-term memories are formed. This has been verified in studies on sea mollusks, fruit flies, and mice. The key property of MEM 1414 is that it accelerates the production of the CREB proteins. In lab tests, aged animals given MEM 1414 were able to form long-term memories significantly faster than a control group. Scientists are also beginning to isolate the precise biochemistry required in the formation of long-term memories, at both the genetic and the molecular level. Once the process of memory formation is completely understood, therapies will be devised to accelerate and strengthen this key process. Not only the aged and Alzheimer’s patients but eventually the average person may well benefit from this “brain boost.
