Definitions:

Electrical Polarization

The phenomenon where in a material, or in the particles of the material, there is a separation of charge leading to one part becoming more positively charged and another part more negatively charged.

Synaptic Vesicles

Membrane-bound sacs in the synapse that store neurotransmitters and release them into the synaptic cleft to transmit neural signals between neurons.

Action Potential

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

Threshold

The minimum level of stimulus intensity required to activate a sensory system or produce a response in a physiological or psychological system.
