where do chemical on the brain come from
The chemical may be pumped back into the nerve ending it comes from, a process known as reuptake, it may be destroyed by enzymes * near the receptor sites, or it may simply spread out into the surrounding area of the brain and be destroyed there.
Brain chemistry is the sum of all the chemical messaging that takes place in the brain, which allows it to carry out its daily functions, such as generating movement, speaking, thinking, listening, regulating the systems of the body, and countless others.
