Definition

Stimulation refers to the activation or excitation of a neuron caused by incoming signals from other neurons or sensory receptors. It is necessary for generating an action potential in a neuron.

Related terms

Action Potential:

A brief electrical impulse that travels down the axon of a neuron, resulting from stimulation exceeding the threshold.

Threshold:

The minimum level of stimulation required to trigger an action potential in a neuron.

Excitatory Signals:

Incoming signals that increase the chances of a neuron reaching its threshold and firing an action potential.
