Definitions:

Resting Potential

The state of a neuron when it is not being stimulated or activated, characterized by a negative charge inside the cell relative to the outside.

Action Potential

A temporary reversal in the electrical polarization of the membrane of a nerve cell, allowing for the transmission of nerve impulses.

Neuroplasticity

The brain's ability to reorganize itself by forming new neural connections throughout life, allowing the neurons (nerve cells) in the brain to compensate for injury and disease and to adjust their activities in response to new situations or changes in their environment.

Brain Cells

Cells that make up the brain, including neurons which transmit information, and glial cells that provide support and protection.
