the key structural components of neurons are (Ans- cell body, dendrites, axon Paul Broca's and Carl Wernicke's research provided early evidence for what? (Ans- localization of function a synapse is (Ans- space between neurons action potentials occur in the (Ans- axon When recording from a single neuron, stimulus intensity is represented in a single neuron by the (Ans- firing rate of the action potentials. Which of the following statements best describes how neurons com...

The behavior of organisms can be divided into three distinct categories. What are they? -Fixed action pattern: (also known as instincts) A stereotyped pattern of behavior elicited by a particular environmental stimuli -Reflexes: inevitable, involuntary response to a stimulus -Learned Behavior: (learning:) a relatively permanent change in behavior or the capacity for behavior due to experience. Be able to define reflex and give an example -reflex: an involuntary response to a stimu...
