Document Summary
At the end of this chapter you should be able to: Understand the structure of the brain and the nervous system. Learn the methods used to study the brain. Descartes, early 1600s: first to think of this notion. Machines, principles of physics, math and astronomy: applied to human behavior for the first time. Consists of all the nerve cells of the peripheral and central nervous systems. The brain directs mental processes and maintains basic life functions. The spinal cord receives sensory input, sends information to the brain, responds with motor output. Divided into two: somatic division and autonomic division. Study of: nature, functions, origins of the nervous system: multidisciplinary; Begins with studying cells of the nervous system. What happens to behavior when brain structures are damaged. Transcranial magnetic stimulation: temporary loss of brain function in isolated areas near surface of brain (just under scalp) Images created from multiple x-ray images of brain. Responses of cell nuclei to magnetic current differ.
