When a single synaptic input fires repeatedly, generating a cumulative effect on the postsynaptic membrane potential, that phenomenon is known as summation.

Question

Quizplus · Accepted Answer

Temporal summation occurs when a single presynaptic neuron fires action potentials so rapidly that the postsynaptic neuron does not have time to return to its resting potential between signals, resulting in a cumulative effect on the membrane potential.
