Definitions:

Depolarization

The process by which a neuron's membrane potential becomes less negative, making the neuron more likely to fire an action potential.

Hyperpolarization

A change in a cell's membrane potential that makes it more negative, moving further away from zero, which decreases the likelihood of generating an action potential.

Sodium

A chemical element, represented by the symbol Na, that plays critical roles in the body, including maintaining fluid balance and conducting nerve impulses.

Synaptic Cleft

The tiny gap between neurons at a synapse, through which neurotransmitters are released to transmit signals from one neuron to another.
