The combined effects of inhibitory and excitatory effects on a postsynaptic cell will decide whether that cell generates an action potential. This principle is called ________.
A) threshold
B) internalization
C) summation
D) potentiation

Question

Quizplus · Accepted Answer

Summation refers to the combined effects of inhibitory and excitatory inputs on a postsynaptic cell. If the sum of these inputs exceeds a certain threshold, the cell will generate an action potential. Internalization and potentiation are not relevant to this process, and threshold is a general concept that refers to the minimum level of stimulation necessary for a neuron to fire.
