________ occurs when several excitatory postsynaptic potentials (EPSPs)arrive at the axon hillock from different dendritic locations and then depolarize the postsynaptic cell to threshold for an action potential
A)Temporal summation
B)Spatial summation
C)A normal action potential

Question

Quizplus · Accepted Answer

Spatial summation occurs when EPSPs arrive at different dendritic locations and depolarize the postsynaptic cell to threshold for an action potential. Temporal summation occurs when EPSPs arrive at the axon hillock at different times and accumulate to reach threshold for an action potential. Choice C is not relevant to this question as it is a general term for the firing of an action potential.
