When a second excitatory postsynaptic potential (EPSP)arrives at a single synapse before the effects of the first have disappeared,what results?
A)hyperpolarization
B)spatial summation
C)temporal summation
D)inhibition of the impulse

Question

Quizplus · Accepted Answer

When a second EPSP arrives before the effects of the first have disappeared, temporal summation occurs. This means that the two EPSPs are added together, resulting in a larger depolarization of the postsynaptic membrane and a greater likelihood of the neuron firing an action potential.
