Cholinergic Neurons and Receptors
Acetylcholine is a neurotransmitter in the central and peripheral nervous systems that affects plasticity, arousal, and reward.

Adrenergic Neurons and Receptors
Adrenergic receptors are molecules that bind catecholamines. Their activation leads to overall stimulatory and sympathomimetic responses.

Agonists, Antagonists, and Drugs
Drugs effecting cholinergic neurotransmission may block, hinder, or mimic the action of acetylcholine and alter post-synaptic transmission.
