key term - Threshold potential

Definition

The threshold potential refers to the minimum level of stimulation that a neuron must receive in order to generate an action potential. It is the point at which the neuron's membrane potential becomes depolarized enough to initiate an electrical impulse.

Resting Potential:

The resting potential is the normal, stable state of polarization of a neuron when it is not receiving any signals or stimuli. It represents the baseline electrical charge of the neuron.

Excitatory Threshold: The excitatory threshold refers to the specific level of stimulation required for a neuron to become excited and reach its threshold potential, triggering an action potential.

Subthreshold Stimulation: Subthreshold stimulation refers to levels of stimulation that are below the threshold potential and do not trigger an action potential. The neuron remains in its resting state without generating an electrical impulse.
