Comprehensive Practice Questions &
Study Guide
**1. The monoamine hypothesis of depression states that:**
A) Depression is caused by an excess of monoamine neurotransmission
B) Depression is caused by a deficiency in monoamine neurotransmission
C) Depression results from maladaptive cognitions and distorted thoughts
D) Depression is primarily a genetic disorder with no neurotransmitter involvement
,**Answer: B**
*Rationale: The monoamine hypothesis posits that depression is caused by a deficiency in monoamine
neurotransmission (serotonin, norepinephrine, dopamine), and mania is the opposite, resulting from an
excess. This hypothesis is foundational to understanding antidepressant mechanisms but has not been
definitively proven .*
---
**2. When voltage-sensitive sodium channels are open and activated, the flow of sodium is:**
A) Into the neuron
B) Out of the neuron
C) Stopped completely
D) Reversed direction
**Answer: A**
*Rationale: When voltage-sensitive sodium channels open, sodium flows into the neuron, causing
depolarization. This is a fundamental principle of neuronal signal transmission .*
---
**3. The alpha 2 delta subunit of voltage-sensitive calcium channels is believed to help regulate:**
A) Opening and closing of the voltage-sensitive calcium channel
B) The reuptake of serotonin
C) The release of GABA
D) The metabolism of dopamine
, **Answer: A**
*Rationale: The alpha 2 delta subunit of voltage-sensitive calcium channels is believed to help regulate
the opening and closing of the voltage-sensitive calcium channel. This mechanism is targeted by
medications like gabapentin for various psychiatric and pain conditions .*
---
**4. The orbitofrontal cortex (OFC) affects the amygdala by:**
A) Only inhibiting the amygdala
B) Only activating the amygdala
C) Both inhibiting and activating the amygdala
D) Having no effect on the amygdala
**Answer: C**
*Rationale: The orbitofrontal cortex (OFC) both inhibits and activates the amygdala, playing a crucial
role in emotional regulation and decision-making. This dual effect is important for understanding the
neurobiology of anxiety and impulse control disorders .*
---
**5. Wernicke's area is associated with which function?**
A) Speech production
B) Speech comprehension
C) Motor coordination
