WebResting membrane potential = difference in voltage (electrical charge) across the membrane of a neuron at rest In the absence of disturbance, there is slightly more negative electrical potential inside the neuron vs. outside. **Membrane is “POLARIZED” -- Created by a selective separation of ions across the cell membrane In mammals ~ -70 ... WebWhen the neuron is at rest, there is a baseline level of ion flow through leak channels. However, the ability of neurons to function properly and communicate with other neurons and cells relies on ion flow through channels other than the non-gated leak channels. We will cover how these channels open in a later lesson.
