In ________, activity at an axoaxonic synapse increases the amount of neurotransmitter released when anaction potential arrives at the axon terminus.
A) presynaptic inhibition
B) presynaptic facilitation
C) spatial summation
D) temporal summation
E) spatial facilitation

Question

Quizplus · Accepted Answer

The statement describes presynaptic facilitation, which is when activity at an axoaxonic synapse increases the amount of neurotransmitter released when an action potential arrives at the axon terminus. Presynaptic inhibition, on the other hand, decreases the amount of neurotransmitter released. Spatial and temporal summation refer to the integration of postsynaptic potentials, and spatial facilitation is not a recognized term in neuroscience.
