The increase in synaptic strength that occurs in long-term potentiation is due to a physical modification of the synapse to include
A) more postsynaptic NMDA receptors.
B) more postsynaptic AMPA receptors.
C) fewer synaptic connections.
D) more postsynaptic GABA contacts.
E) fewer presynaptic GABA contacts.

Question

Quizplus · Accepted Answer

The physical modification in long-term potentiation includes an increase in the number of postsynaptic AMPA receptors, which leads to a greater response to neurotransmitter release and thus an increased synaptic strength.
