Chemicals That Fix the Brain

Repair of brain chemicals The discovery of brain healing starts with the discovery of frequently occurring problems. Why do children with the same kind of injury have a permanent disability, whereas children who suffer from brain damage often recover completely. Ronald Kalil, a neuroscientist at the University of Wisconsin, is pursuing this problem (15). His research on kittens shows that the entire brain cell network can bypass damaged areas. He discovered that another part of the cells in their brain began treating sight, so young animals destroyed by the main visual center can still learn to look normal.

"We use a powerful chemical fixative glutaraldehyde to rapidly coagulate synapses and prevent spoilage," Nectome says on their website. "However, even with glutaraldehyde fixation, the brain can decompose slowly. In order to solve this problem, we used extremely cold (-122 ° C!) To extend the storage time to hundreds of years "Strong research tools can bring great benefits to society, but he emphasizes that this technology is still in its early stages. "The most important point is that when trying to build a way to save memory, the technology is still at the research stage," McIntyre told us. "People are very interested in the future of this technology, but it is important to know that we are not currently providing clinical brain preservation whatever the headline is, and in the near future We will not provide it. "

For years, scientists have preserved brain tissue using chemical substances and observed their microstructure using a high magnification microscope. Natalya Korogod et al. Now indicate that these chemicals or fixatives cause tissue atrophy. This gives the wrong impression that the cells are tightly packed. This leads to misunderstanding of the structure of the brain. For example, components such as synapses that neurons use to communicate with each other are immersed in an aqueous environment rather than being surrounded by adjacent cells as previously thought.

It is said that the brain becomes chemically unbalanced if too much or too few chemical substances are contained in the brain (called neurotransmitters). Neurotransmitters are natural chemicals that help to promote communication between neurons. Examples include norepinephrine and serotonin. Indeed, it is highly contested by the medical community. Researchers believe that the chemical imbalance hypothesis is more like a rhetorical device. It does not actually capture the real complexity of these diseases. In other words, mental disorders are not only caused by chemical imbalances in the brain. There are still a lot of things
