layers of cells on the outer surface of the cerebral hemisphere of the forebrain

Question 4

central sulcus

Answer 4

one of the deepest grooves in the surface of the cerebral cortex

Question 5

columns

posterior section of the cerebral cortex

Question 8

Klüver-Bucy syndrome

a behavioral disorder caused by temporal lobe damage

Question 9

frontal lobe

Answer 9

section of cerebral cortex that extends from the central sulcus to the anterior limit of the brain

Question 10

laminae

Answer 10

layer of cell bodies that are parallel to the surface of the cerebral cortex and separated from each other by layers of fibers

Question 11

postcentral gyrus

Answer 11

area just posterior to the central gyrus; primary receptor site for touch and other body sensations

Question 12

parietal lobe

Answer 12

section of the cerebral cortex between the occipital lobe and the central sulcus

Question 13

delayed-response task

Answer 13

assignment in which an animal must respond on the basis of a signal that it remembers but that is no longer present

Question 14

precentral gyrus

Answer 14

the posterior portion of the frontal lobe of the cortex, specialized for control of movement

Question 16

prefrontal lobotomy

Answer 16

surgical disconnection of the prefrontal cortex from the rest of the brain

Question 17

prefrontal cortex

Question 18

temporal lobe

Answer 18

the lateral portion of each hemisphere, near the temples
