How does temporal summation create an action potential?
A) Potentials are generated on several dendrites at the same time to trigger threshold and the production of an action potential.
B) It is frequency modulated and of the same amplitude for intensity.
C) The temporal lobe in the brain stimulates EPSPs to trigger an action potential.
D) Two or more postsynaptic potentials are generated in rapid succession at the same synapse before they can dissipate, thereby exceeding threshold.
E) Generator potentials are at the same tempo on adjacent neurons.

Question

Quizplus · Accepted Answer

Temporal summation occurs when two or more postsynaptic potentials are generated in quick succession at the same synapse before they can dissipate. This can lead to the combined potentials exceeding the threshold needed to trigger an action potential.
