Neurotransmitter

Chemical substances released at the end of a nerve fiber by the arrival of a nerve impulse, which, by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.

Memory Formation

The process by which experiences are encoded, stored, and retrieved in the brain.

Acetylcholine

A neurotransmitter in both the peripheral and central nervous systems that is involved in muscle activation, memory formation, and learning.

Neurotransmitter
