Chapter 2: Neurons and Glia 1. Introduction * Although there are many neurons in the human brain (about 100 billion)‚ glia outnumbers neurons by tenfold. 1:10 ratio. * Neurons are the most important cells for the unique functions of the brain. * Neurons sense changes in the environment‚ communicate these changes to other neurons‚ and command the body’s responses to these situations. * Glia‚ or glial cells‚ are thought to contribute to brain function mainly by insulating‚

What is Brain Chemistry? Brain chemistry or neurochemistry is the complex system which allows the brain to function with the use of chemicals known as neurotransmitters which move information around in the brain. Every person’s brain chemistry is slightly different‚ and a number of things can play a role in the levels of various neurotransmitters in the brain‚ and how those chemicals affect the brain’s function. It is believed that difference in brain chemistry may explain a variety of behavioral
