Question

Temporal summation refers to:
summation of action potentials in the temporal cortex.
summation of postsynaptic potentials on a neuron occurring closely together in
time.
summation of postsynaptic potentials at different places on a neuron at the
same time.
summation of postsynaptic potentials in the temporal cortex.

Expert Solution

Step 1

Introduction

The process of summing, which encompasses both spatial and temporal summation, decides whether or not an action potential will be produced by the cumulative effects of excitatory and inhibitory signals from both many simultaneous inputs (spatial summation) and from repeated inputs (temporal summation). Summation may or may not reach the threshold voltage to initiate an action potential depending on the sum of many different individual inputs.
