Research suggests that LTP increases synaptic effectiveness by:
A) increasing the size of axons.
B) increasing the firing rate of presynaptic neurons.
C) increasing the number of synapses on postsynaptic dendrites.
D) decreasing the amount of glutamate released by presynaptic neurons.

Question

Quizplus · Accepted Answer

LTP increases the number of synapses on postsynaptic dendrites, allowing for more efficient communication between neurons. This is often accompanied by an increase in the strength of existing synapses, but not by increasing the size of axons or decreasing the amount of glutamate released by presynaptic neurons. Increasing the firing rate of presynaptic neurons may contribute to LTP, but is not the primary mechanism by which it occurs.
