C) New synapses are built.
D) Postsynaptic neurons release more neurotransmitters.

Question

Quizplus · Accepted Answer

Long-term potentiation (LTP) is a process by which synaptic connections between neurons become stronger with frequent activation. The mechanisms proposed for LTP include postsynaptic receptors becoming more responsive, changes in presynaptic neurons via retrograde messengers, and the building of new synapses. However, the release of more neurotransmitters by postsynaptic neurons is not a mechanism of LTP; typically, changes in neurotransmitter release are associated with presynaptic mechanisms.
