The buildup of depolarization when EPSPs arrive at several places on the neuron is called ________ summation.
A)threshold
B)spatial
C)temporal
D)chemical
E)electrical

Question

Quizplus · Accepted Answer

Spatial summation refers to the addition of EPSPs arriving at multiple places on the neuron, which can lead to depolarization reaching the threshold for an action potential. Temporal summation refers to the addition of EPSPs arriving in rapid succession at a single location on the neuron, while chemical and electrical summation are not relevant terms in this context. The threshold refers to the minimum level of depolarization required to trigger an action potential, rather than the buildup of depolarization itself.
