Spatial summation is characterized by:
A) several presynaptic neurons releasing neurotransmitter simultaneously.
B) several presynaptic neurons releasing neurotransmitter in a sequential pattern.
C) several postsynaptic neurons receive sequential inputs from several presynaptic neurons.
D) a single presynaptic neuron firing multiple times in rapid succession.
E) a single presynaptic neuron directly contacting several postsynaptic neurons.

Question

Quizplus · Accepted Answer

Spatial summation occurs when multiple presynaptic neurons release neurotransmitters at the same time, affecting a single postsynaptic neuron and potentially triggering an action potential if the combined effect is sufficient.
