NR 546 FINAL EXAM
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
Rationale: The mesolimbic dopamine pathway, projecting from the ventral tegmental
area (VTA) to the nucleus accumbens, is the brain’s primary reward and pleasure
circuit. It is critically involved in reinforcement, motivation, and addiction.
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
Rationale: Chronic nicotine exposure causes desensitization of nicotinic acetylcholine
receptors (nAChRs). Upon cessation, these receptors resensitize and upregulate,
leading to withdrawal symptoms and intense 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
Rationale: The reactive reward system (mesolimbic pathway) responds to immediate
cues predicting reward or punishment, driving motivated behaviors including drug-
seeking.
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
Rationale: The amygdala processes emotional memories and conditioned cues
associated with drug use. It communicates with the VTA to trigger dopamine release in
response to drug-associated cues, driving craving.
5. A 45-year-old patient has tried unsuccessfully to quit smoking several times
over the past ten 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
, Rationale: Nicotine’s reinforcing effects are primarily mediated by activation of α4β2
nicotinic acetylcholine receptors on postsynaptic dopamine neurons in the VTA, leading
to increased dopamine release in the nucleus accumbens.
6. 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
Rationale: Chronic nicotine causes desensitization of nicotinic receptors; cessation
leads to resensitization/upregulation, producing withdrawal craving. (See Q2.)
7. A 44-year-old patient has schizophrenia and comorbid alcohol abuse disorder.
Alcohol has what effect on GABA and glutamate in the ventral tegmental area?
A. Increases GABA and decreases glutamate
B. Increases both GABA and glutamate
C. Decreases GABA and increases glutamate
D. Decreases both GABA and glutamate
Correct Answer: A. Increases GABA and decreases glutamate
Rationale: Alcohol potentiates GABA-A receptors (increasing GABAergic inhibition) and
inhibits NMDA glutamate receptors (decreasing glutamate excitation). In the VTA, this
alters the balance of excitation/inhibition and can influence dopamine neuron firing.
8. A 26-year-old patient with ADHD has recently entered a drug rehabilitation
center following arrest for possession of cocaine. The cocaine use in this patient
may be an attempt at self-medication for ADHD symptoms because it inhibits the
dopamine transporter (but is not itself taken up into the neuron by the
transporter). Thus, cocaine has the same action at the dopamine transporter as:
A. Cocaine has the same actions at the dopamine transporter as amphetamine
B. Cocaine has the same actions at the dopamine transporter as methylphenidate
C. A and B
