Question

Quizplus · Accepted Answer

When a second EPSP arrives before the effects of the first have disappeared, it is called temporal summation. This occurs because the second EPSP adds onto the first, making the membrane potential more positive and making it more likely for an action potential to be generated. This is a form of synaptic integration that allows for the summation of different inputs to create a larger overall signal.
