Having received messages from hundreds or thousands of other neurons, a postsynaptic neuron will fire if
A) all of its incoming messages are inhibitory in nature.
B) it is being stimulated by neuromodulators rather than simple neurotransmitters.
C) the combined incoming excitatory and inhibitory signals produce a large enough depolarization.
D) the combined incoming excitatory and inhibitory signals produce a large enough hyperpolarization.

Question

Quizplus · Accepted Answer

The firing of a postsynaptic neuron is determined by the net effect of all incoming signals. If the sum of excitatory and inhibitory inputs leads to sufficient depolarization, reaching the threshold, the neuron will fire an action potential. This process is known as the integration of synaptic inputs.
