Forming memories in the brain generally involves strengthening existing synaptic connections and:
A) short-term potentiation.
B) decreasing the amount of neurotransmitters released.
C) increasing the number of synaptic connections.
D) decreasing the number of synaptic connections.

Question

Quizplus · Accepted Answer

Forming memories generally involves the strengthening of existing synaptic connections, but it may also involve the creation of new synaptic connections. Thus, the increasing number of synaptic connections is the best choice. Short-term potentiation can occur as a result of enhanced synaptic activity, but it is not a necessary part of forming memories. Decreasing the amount of neurotransmitters released and decreasing the number of synaptic connections would both be counterproductive for memory formation.
