Definitions:

EPSP

Stands for Excitatory Postsynaptic Potential, a temporary increase in postsynaptic membrane potential caused by the flow of positively charged ions into the postsynaptic cell, making it more likely that the cell will fire an action potential.

Depolarization

A decrease in membrane potential that makes the interior of a cell less negative compared to the outside, crucial for nerve impulse transmission.

Voltage-Gated Channel

A type of protein channel in cell membranes that opens or closes in response to changes in electrical membrane potential.

Synaptic Vesicle

Secretory vesicle in the presynaptic terminal containing neurotransmitter substances.
