3. chapter 3 – neuron and the brain. university of minnesota; jennifer walinga; and charles stangor. chapter contents. 3.1 the neuron is the building block of the nervous system. 3.2 our brains control our thoughts, feelings, and behavior. 3.3 psychologists study the brain using many different methods. 3.4 putting it all together: the nervous. The part of the neuron that carries messages destined for other neurons. terminal buttons. small bulges at the end of axons that send messages to other neurons. myelin sheath. a protective coating of fat and protein that wraps around an axon. action potential. an electric nerve impulse that travels through a neuron's axon when it is set off by.

Brain and spinal cord. peripheral nervous system (pns) the sensory and motor neurons that connect the cns to the rest of the body. sympathetic nervous system. fight or flight response. parasympathetic nervous system. a set of nerves that helps the body return to a normal resting state (rest and digest) somatic nervous system. Law of perceptual organization that states that every stimulus pattern is seen in such a way that the resulting structure is as simple as possible. also called the law of good figure and the law of simplicity. cognitive psychology (goldstein, 4th edition) learn with flashcards, games, and more — for free. The thalamus is a sensory relay for the brain. all of our senses, with the exception of smell, are routed through the thalamus before being directed to other areas of the brain for processing ( figure 3.22 ). figure 3.22 the thalamus serves as the relay center of the brain where most senses are routed for processing. The goal of this chapter is to become familiar with the anatomical structure of neurons and to understand how neurons communicate by electrochemical signals to process sensory information and produce complex behaviors. a basic knowledge of the structure and function of neurons is a necessary foundation as you move forward in the field of.
