A) more postsynaptic GABA contacts.
B) more postsynaptic AMPA receptors.
C) fewer synaptic connections.
D) more postsynaptic NMDA receptors.
E) fewer presynaptic GABA contacts.

Question

Quizplus · Accepted Answer

Long-term potentiation (LTP) is a process by which synaptic connections between neurons become stronger with frequent activation. This strengthening is largely due to an increase in the number of AMPA receptors on the postsynaptic neuron's membrane, which enhances its responsiveness to glutamate, the primary excitatory neurotransmitter in the brain.
