Temporal summation
A)occurs when a single neuron releases neurotransmitter rapidly.
B)occurs because of the convergence of many neurons on a single postsynaptic cell.
C)only involves excitatory postsynaptic potentials.
D)only involves inhibitory postsynaptic potentials.

Question

Quizplus · Accepted Answer

Temporal summation occurs when a single presynaptic neuron releases neurotransmitter rapidly, leading to a build-up of postsynaptic potentials that add together to reach the threshold for an action potential. It does not require the convergence of multiple neurons, and can involve both excitatory and inhibitory postsynaptic potentials.
