  4. Psychologists have described the human nervous system as the communication and control center for the body. The nervous system allows us to take in information from the environment, communicate the information to different parts of the body, and coordinate the body’s response. The nervous system itself is made up of neurons, or nerve cells, that communicate with each other by receiving and transmitting electrochemical signals, called neurotransmission. All human behavior is made possible by the activity of individual neurons working together in the nervous system. Think about a simple action you do every day, like answering your phone. When you perform this routine act, what are the individual neurons in your nervous system doing to make it possible?
