Question

Quizplus · Accepted Answer

Temporal summation refers to the phenomenon where a synapse is stimulated a second time before the effect of a first stimulus at the synapse has terminated. This can result in the combining of multiple EPSPs, potentially bringing a postsynaptic cell to threshold and triggering an action potential.
