,1. Question 1 : Which brain structure is primarily associated
with the formation of declarative memory?
- A) Amygdala
- B) Hippocampus
- C) Cerebellum
- D) Thalamus
Correct Answer : B) Hippocampus
Rationale : The hippocampus is critical for the formation of
new declarative memories, which include facts and events.
2. Question 2 : Which of the following neurotransmitters is
most involved in synaptic plasticity, especially long-term
potentiation (LTP)?
- A) Dopamine
- B) Serotonin
- C) Glutamate
- D) GABA
, Correct Answer : C) Glutamate
Rationale : Glutamate is the main excitatory neurotransmitter
involved in synaptic plasticity, particularly in LTP, a mechanism
for strengthening synapses.
3. Question 3 : Which process best describes the mechanism of
synaptic strengthening during learning?
- A) Habituation
- B) Sensitization
- C) Long-term depression (LTD)
- D) Long-term potentiation (LTP)
Correct Answer : D) Long-term potentiation (LTP)
Rationale : LTP is a long-lasting enhancement in signal
transmission between two neurons that results from stimulating
them synchronously.
4. Question 4 : What is the role of NMDA receptors in synaptic
plasticity?
- A) Inhibit calcium influx
- B) Facilitate sodium outflux
- C) Allow calcium entry
Correct Answer : C) Allow calcium entry
Rationale : NMDA receptors are crucial for synaptic plasticity
and memory function as they allow calcium ions to enter the cell,
triggering signaling pathways involved in LTP.
5. Question 5 : During memory consolidation, the transfer of
information to long-term storage primarily occurs between which
brain structures?
- A) Cortex and thalamus
- B) Hippocampus and cortex
- C) Amygdala and basal ganglia
- D) Cerebellum and spinal cord
Correct Answer : B) Hippocampus and cortex
Rationale : The hippocampus initially encodes memories, and
then the information is gradually transferred to the cortex for
long-term storage.
