Brain activity is made possible by the interconnections of neurons and their release of neurotransmitters in response to nerve impulses.

Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body. The human nervous system consists of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord.
