Spatial summation is characterized by:
A) several presynaptic neurons releasing neurotransmitters simultaneously.
B) several presynaptic neurons releasing neurotransmitters in a sequential pattern.
C) several postsynaptic neurons receiving 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 to a single postsynaptic neuron, leading to a stronger cumulative effect.
