Question 16

Associate the brain structure or system below with the letter corresponding to the function for which it is most likely and primarily responsible.
a.regulates expression of basic drive states, e.g., hunger, thirst, sex, and mediates CNS control over endocrine system
b.coordinates balance and the body's movements; potentially involved in reactions to pleasurable stimulation, e.g., orgasm, heroin "rush"
c.regulates emotions and the formation of certain memories; most drugs of abuse enhance dopaminergic activity in this structure/system
d.contain the primary receiving area for auditory information and visual recognition.
e.regulation of slow voluntary movements modified by sensory feedback; loss of dopaminergic input into this area produces symptoms of Parkinson's disease
f.relay station in the brain
g.peripheral nervous system controlling smooth muscle and several glands
h.allows the two cerebral hemispheres to communicate with each other
i.essential for working memory, judging the values of rewards and punishments and predicting future events
j.regulates essential life reflexes, e.g., heart rate, blood pressure
1.____ temporal lobes
2.____ limbic system
3.____ cerebellum
