key term - Resting Potential

Definition

Resting potential refers to the state of a neuron when it's not being stimulated or sending signals. It's the difference in electric charge between the inside and outside of a neuron's cell membrane.

Related terms

Action Potential:

This is an electrical impulse that travels down the axon triggering the release of neurotransmitters. It occurs when a neuron sends information down an axon, away from the cell body.

Threshold:

The level of stimulation required to trigger an action potential in neurons.

Hyperpolarization: An increase in the membrane potential of a cell relative to its normal resting potential, making it less likely for an action potential to occur.
