Neurotransmitter
A chemical substance released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.
EPSP
Excitatory Postsynaptic Potential; a temporary increase in postsynaptic membrane potential due to the flow of positively charged ions into the postsynaptic cell, making it more likely to fire an action potential.
Voltage Change
A change in the electrical potential difference across a membrane, which can initiate an electrical signal or action potential in neurons and other excitable cells.
