Section 1: Week 1 — Neurobiology and Foundations of
Psychopharmacology
Competency 1: Neuroanatomy (limbic system, prefrontal cortex); neurotransmitter systems (serotonin, dopamine,
norepinephrine, GABA, glutamate); receptor subtypes (5-HT2A, D2, GABA-A); synaptic transmission; signal
transduction; neuroplasticity and the neurotrophic hypothesis.

Q1: A PMHNP explains to a patient that depression is associated with dysregulation in brain regions
governing mood and executive function. Which brain region is most directly involved in executive function,
working memory, and top-down regulation of limbic activity?
A. Hippocampus.
B. Prefrontal cortex. [CORRECT]
C. Cerebellum.
D. Medulla oblongata.
Correct Answer: B
Rationale: The prefrontal cortex (PFC) governs executive function, working memory, and top-down regulation of limbic
structures; hypoactivity of the PFC is implicated in depression and other disorders. The hippocampus governs memory
consolidation; the cerebellum coordinates motor activity; the medulla controls autonomic functions.
Q2: The amygdala, hippocampus, hypothalamus, and cingulate gyrus together form the:
A. Reticular activating system.
B. Limbic system, which regulates emotion, motivation, memory, and autonomic-endocrine responses.
[CORRECT]
C. Basal ganglia motor loop.
D. Corticospinal tract.
Correct Answer: B
Rationale: The limbic system (amygdala, hippocampus, hypothalamus, cingulate gyrus, and related structures) regulates
emotion, motivation, memory, and integrated autonomic-endocrine responses. Dysfunction is implicated in mood and anxiety
disorders. The reticular activating system governs arousal; basal ganglia regulate motor loops; the corticospinal tract controls
voluntary movement.
Q3: Which neurotransmitter is primarily implicated in the positive symptoms of schizophrenia
(hallucinations, delusions) and is the principal target of first-generation antipsychotics?
A. Serotonin.
B. Dopamine, particularly overactivity in the mesolimbic pathway. [CORRECT]
C. GABA.
D. Glutamate.
Correct Answer: B
Rationale: Excess dopaminergic activity in the mesolimbic pathway is linked to positive symptoms of schizophrenia.
First-generation antipsychotics block D2 receptors in this pathway. Mesocortical dopamine deficits relate to negative/cognitive
symptoms; nigrostriatal dopamine affects motor control (EPS); tuberoinfundibular dopamine regulates prolactin.

Q4: Which dopaminergic pathway is most directly associated with antipsychotic-induced
hyperprolactinemia?
A. Mesolimbic.
B. Mesocortical.
C. Tuberoinfundibular, where D2 blockade removes dopamine's inhibitory effect on prolactin release.
[CORRECT]
D. Nigrostriatal.
Correct Answer: C
Rationale: Dopamine in the tuberoinfundibular pathway inhibits prolactin release. D2 blockade (especially by risperidone and
FGAs) removes this inhibition, causing hyperprolactinemia (galactorrhea, gynecomastia, amenorrhea). Nigrostriatal blockade
causes EPS; mesolimbic blockade treats positive symptoms; mesocortical blockade may worsen negative symptoms.
Q5: Which of the following correctly pairs a neurotransmitter with its primary clinical implication?
A. Serotonin — motor control only.
B. Norepinephrine — arousal, vigilance, and energy; deficiency linked to depressive symptoms with fatigue
and anhedonia. [CORRECT]
C. GABA — excitatory drive in cortex.
D. Glutamate — primary inhibitory neurotransmitter.
Correct Answer: B
Rationale: Norepinephrine regulates arousal, vigilance, energy; deficits are linked to fatigue, anhedonia, and depressive
symptoms. Serotonin regulates mood, sleep, appetite, impulse control. GABA is the primary inhibitory neurotransmitter.
Glutamate is the primary excitatory neurotransmitter.
Q6: GABA-A receptor activation produces fast inhibitory transmission by:
A. Opening chloride channels, hyperpolarizing the neuron. [CORRECT]
B. Opening sodium channels, depolarizing the neuron.
C. Blocking calcium channels.
D. Activating adenylate cyclase.
Correct Answer: A
Rationale: GABA-A is a ligand-gated chloride channel. Binding of GABA (or benzodiazepines/barbiturates as positive
allosteric modulators) opens the channel, allowing Cl- influx, hyperpolarizing the neuron and reducing excitability. This
explains the anxiolytic, sedative, and anticonvulsant effects of benzodiazepines and barbiturates.

Q7: The NMDA receptor, implicated in schizophrenia and depression, is a glutamate receptor that:
A. Is a G-protein-coupled receptor activating cAMP.
B. Is a ligand-gated calcium channel requiring glycine co-activation; dysfunction contributes to glutamatergic
hypofunction hypotheses of schizophrenia. [CORRECT]
C. Is a chloride channel.
D. Is a serotonin receptor subtype.
Correct Answer: B
Rationale: The NMDA receptor is a ligand-gated calcium channel requiring glutamate and glycine co-activation. NMDA
hypofunction is implicated in schizophrenia (ketamine, an NMDA antagonist, produces psychotic and negative-like
symptoms) and depression (ketamine produces rapid antidepressant effects via AMPA and downstream BDNF/mTOR
signaling).
Q8: Second-generation antipsychotics like clozapine and olanzapine have a higher affinity for which receptor,
contributing to their atypical profile?
A. D2 receptor only.
B. 5-HT2A receptor antagonism combined with relatively weaker D2 blockade, contributing to lower EPS risk
and broader efficacy. [CORRECT]
C. Muscarinic antagonist effect alone.
D. Alpha-1 antagonist effect alone.
Correct Answer: B
Rationale: Atypical (second-generation) antipsychotics combine 5-HT2A antagonism with relatively weaker D2 blockade,
contributing to lower EPS risk and efficacy against negative/cognitive symptoms. They also have variable affinity for H1,
alpha-1, and muscarinic receptors, driving sedation, weight gain, and orthostasis.
Q9: The monoamine hypothesis of depression proposes that:
A. Excess serotonin causes depression.
B. Deficiencies in monoamines (serotonin, norepinephrine, dopamine) contribute to depressive symptoms,
supporting the use of agents that increase monoaminergic tone. [CORRECT]
C. Glutamate deficiency is the sole cause.
D. GABA excess causes depression.
Correct Answer: B
Rationale: The monoamine hypothesis posits that deficiencies in serotonin, norepinephrine, and/or dopamine underlie
depressive symptoms. Antidepressants increase monoaminergic neurotransmission (SSRIs, SNRIs, TCAs, MAOIs). The
hypothesis is incomplete; downstream neuroplastic changes (BDNF) and glutamate modulation are now recognized as
important.
