1. Which of the following is considered the pleasure center of the brain?
A. Cortico-striatal-thalamic-cortical loop
B. Mesolimbic dopamine pathway
C. Mesocortical dopamine pathway
D. None of the above
CORRECT ANSWER: B. Mesolimbic dopamine pathway
,Explanation: The mesolimbic dopamine pathway, which projects primarily from
the ventral tegmental area (VTA) to the nucleus accumbens and related limbic
structures, is strongly involved in reward, reinforcement, motivation, and the
pleasurable aspects of many drugs of abuse.
2. A 35-year-old cigarette smoker would like to quit but is nervous because
she typically craves a cigarette approximately every 2 hours. The craving and
withdrawal are due to:
A. Desensitization of nicotinic receptors
B. Resensitization of nicotinic receptors
C. Desensitization of muscarinic receptors
D. Resensitization of muscarinic receptors
CORRECT ANSWER: B. Resensitization of nicotinic receptors
Explanation: Chronic nicotine exposure causes nicotinic acetylcholine receptor
adaptations, including desensitization followed by receptor upregulation. As
nicotine levels fall, previously desensitized receptors become resensitized,
contributing to withdrawal symptoms and renewed craving.
3. The reactive reward system signals the immediate prospect of pleasure or
pain and triggers drug-seeking behavior.
,A. True
B. False
CORRECT ANSWER: A. True
Explanation: Reward circuitry evaluates salient stimuli and helps generate
motivated behaviors. In substance use disorders, drug-associated cues can activate
these circuits and promote craving and drug-seeking behavior.
4. What role does the amygdala play in substance abuse?
A. Releases phasic bursts of dopamine to the nucleus accumbens when drugs of
abuse are present
B. Communicates to the ventral tegmental area when cues related to drugs of
abuse are present
C. Site of binding for most drugs of abuse
D. A and B
E. A, B, and C
CORRECT ANSWER: B. Communicates to the ventral tegmental area when
cues related to drugs of abuse are present
Explanation: The amygdala is important in emotional learning and the
association of environmental cues with drug effects. Drug-related cues can
, activate amygdala circuitry and influence the VTA and other reward structures,
contributing to conditioned craving and drug-seeking.
5. A 45-year-old patient has tried unsuccessfully to quit smoking several
times over the past 10 years. Nicotine's actions at which receptors are
considered primarily responsible for its reinforcing effects?
A. Alpha-4-beta-2 postsynaptic receptors in the ventral tegmental area
B. Alpha-7 postsynaptic receptors in the prefrontal cortex
C. A and B
D. Neither A nor B
CORRECT ANSWER: A. Alpha-4-beta-2 postsynaptic receptors in the
ventral tegmental area
Explanation: Nicotine produces much of its reinforcing effect through
stimulation of neuronal nicotinic acetylcholine receptors, particularly α4β2-
containing receptors. Activation of these receptors in the VTA facilitates
dopamine signaling within the mesolimbic reward pathway.

she typically craves a cigarette approximately every 2 hours. The craving and
withdrawal are due to:
