The buildup of depolarization when EPSPs arrive in rapid succession is called ________ summation.
A)temporal
B)spatial
C)electrical
D)chemical
E)perforal

Question

Quizplus · Accepted Answer

Temporal summation occurs when EPSPs arrive at a synapse in rapid succession, causing depolarization to build up over time. Spatial summation, on the other hand, occurs when EPSPs arrive at different synapses simultaneously and their effects are added together. Electrical and chemical summation are not valid terms. "Perforal" is not a recognized term in physiology.
