When multiple presynaptic neurons release neurotransmitter at various locations onto the postsynaptic neuron at the same time, this results in
A) suprathreshold hyperpolarization.
B) temporal summation.
C) spatial summation.
D) several action potentials.

Question

Quizplus · Accepted Answer

Spatial summation occurs when multiple presynaptic neurons release neurotransmitters at different locations on the postsynaptic neuron simultaneously, leading to a combined effect that can trigger an action potential if the threshold is reached.
