Temporal summation on a postsynaptic membrane
A)Refers to the effect on the membrane of one (or more) synaptic event before the effects of a previous synaptic event have died away
B)Refers only to addition of EPSPs
C)Refers only to the effect of stimulating different synapses repeatedly
D)Inevitably leads to action potentials in the axon
E)Is described by none of these choices

Question

Temporal summation refers to the cumulative effect of multiple synaptic events that occur in rapid succession before the effects of previous events have dissipated. This can result in the generation of an action potential if the summation exceeds the threshold for firing. It can involve both EPSPs and IPSPs and can occur at a single synapse or multiple synapses.
