Domino Effect

A chain reaction where a small change causes a similar change nearby, leading to a sequence of events with potentially large impacts.

Absolutely Refractory Period

A phase immediately following the firing of a nerve in which the neuron is unable to fire again, ensuring the unidirectional flow of nerve impulses.

Resting Membrane Potential

The electrical potential difference across the membrane of a neuron at rest, typically around -70mV.

Refractory Periods

The period immediately following an action potential during which a neuron is incapable of firing another action potential, ensuring the unidirectional flow of nerve impulses.
