Definition

The difference of electrical charge between the inside and outside of a neuron when it is not actively transmitting a signal.

Etymology

From the Latin 'rest' meaning 'repose' and the term 'potential', which refers to the stored energy.

Example

The resting potential of a neuron is typically around -60 mV, with the inside being more negative than the outside.
