The Brain, Neurons and Brain Chemistry

Author(s): Nancy P. Moreno, PhD, Barbara Z. Tharp, MS, and Tadzia GrandPré, PhD

What Is a Neuron?

The human brain is the most complex structure in the known universe. Consisting of close to 100 billion nerve cells (and many times that number of supporting cells), the brain is the center of our thoughts and emotions. It receives and processes information from the world around us, directs our movements and controls automatic functions of our bodies. Amazingly, virtually all functions of the brain and the rest of the nervous system are based on communication among nerve cells, also known as neurons.
