Learning & Memory
FINAL ASSESSMENT GUIDE

,1. Which brain structure is primarily involved in the
consolidation of long-term memories?
- A) Amygdala
- B) Hippocampus
- C) Cerebellum
- D) Thalamus
- Correct Answer: B) Hippocampus
- Rationale: The hippocampus is crucial for the
consolidation and retrieval of long-term declarative memories.
2. What type of memory is most likely to be affected by damage
to the medial temporal lobe?
- A) Procedural memory
- B) Sensory memory
- C) Short-term memory
- D) Episodic memory
- Correct Answer: D) Episodic memory
- Rationale: The medial temporal lobe, including the
hippocampus, is heavily involved in the formation and recall of
episodic memories.

,3. Which neurotransmitter is most closely associated with the
synaptic plasticity underlying learning and memory?
- A) Dopamine
- B) GABA
- C) Serotonin
- D) Glutamate
- Correct Answer: D) Glutamate
- Rationale: Glutamate is the primary excitatory
neurotransmitter involved in synaptic plasticity mechanisms such as
long-term potentiation (LTP).
4. Long-term potentiation (LTP) is believed to involve which of
the following cellular changes?
- A) Reduced postsynaptic receptor density
- B) Increased presynaptic neurotransmitter release
- C) Decreased synaptic strength
- D) Reduced dendritic spine density
- Correct Answer: B) Increased presynaptic
neurotransmitter release
- Rationale: LTP involves enhanced presynaptic
neurotransmitter release along with postsynaptic receptor changes,
leading to increased synaptic strength.

, 5. The NMDA receptor is unique because it acts as a coincidence
detector, requiring which two conditions to be met?
- A) Simultaneous presynaptic calcium influx and postsynaptic
magnesium unblock
- B) Simultaneous presynaptic neurotransmitter release and
postsynaptic depolarization
- C) Simultaneous inhibition of GABA and activation of
acetylcholine receptors
- D) Simultaneous action potential back-propagation and
neurotransmitter release
- Correct Answer: B) Simultaneous presynaptic
neurotransmitter release and postsynaptic depolarization
- Rationale: The NMDA receptor requires both glutamate
binding (neurotransmitter release) and postsynaptic membrane
depolarization to remove the magnesium block for ion flow.
6. In the context of Hebbian learning, the phrase "cells that fire
together, wire together" refers to which concept?
- A) Neural synchronization
- B) Spike-timing-dependent plasticity
- C) Retrograde signaling
- D) Synaptic vesicle recycling
- Correct Answer: B) Spike-timing-dependent plasticity
