The net effect of excitatory and inhibitory signals is known as ___.
A) depolarization
B) hyperpolarization
C) threshold of excitation
D) summation

Question

Quizplus · Accepted Answer

The net effect of excitatory and inhibitory signals is known as summation. This is because the synaptic inputs are added together at the postsynaptic neuron and their net effect determines whether the neuron depolarizes or hyperpolarizes. The threshold of excitation refers to the minimum amount of depolarization needed to generate an action potential, which is not directly related to the balance of excitatory and inhibitory signals.
