Temporal summation on a postsynaptic neuron takes place when
A) a single presynaptic input causes two EPSPs to develop in rapid succession
B) an EPSP and an IPSP occur simultaneously and cancel each other out
C) two EPSPs develop simultaneously from different presynaptic inputs
D) two action potentials from two presynaptic inputs causes two action potentials to develop
E) none of these

Question

Quizplus · Accepted Answer

Temporal summation occurs when multiple EPSPs from a single presynaptic input occur in rapid succession, potentially reaching the threshold for the postsynaptic neuron to fire an action potential. The other choices (B-D) do not accurately describe temporal summation.
