Definitions:

Absolute Refractory Period

The period immediately following an action potential during which a neuron is completely unable to fire another action potential, regardless of the strength of the stimulus.

Action Potential

A temporary inversion of the electrical potential across the membrane of a nerve or muscle cell, allowing for the transmission of signals.

Hebbian Learning

Hebbian learning is a theory in neuroscience that proposes an increase in synaptic efficacy arises from the presynaptic cell's repeated and persistent stimulation of the postsynaptic cell, foundational for understanding the adaptation of the brain during learning.

Depolarizing

A process in which a cell's membrane potential becomes less negative, often leading to the initiation of an action potential in neurons.
