Neurotransmitters are chemicals released from the axon terminal of a sending neuron into the synaptic cleft where they then bind to a receiving neuron instructing the cell to fire or not fire. Neurotransmitters are excitatory or inhibitory.

There are many neurotransmitters involved with higher-level brain functions such as euphoria, sleep initiation, and social behavior. Here are some that fall under the monoamine classification:

acetylcholine - learning, movement, memory

norepinephrine - social behavior, eating, learning, memory

dopamine - emotional behavior, attention, learning, addiction, pleasure, euphoria

serotonin - sleep, arousal, depression

endorphins - pain reduction, learning, emotional behavior

glutamate - learning
