Calcium entering nerve terminals triggers the release of GABA, glutamate, and acetylcholine, and these neurotransmitters directly regulate transitions between sleep and wakefulness.
See the technical phrasing
Calcium influx into presynaptic terminals is required for the release of GABA, glutamate, and acetylcholine, which regulate sleep-wake states.
When a nerve cell fires, calcium rushes into the tip of its output branch through special channels. This calcium builds up in a tiny space right where the nerve connects to the next cell. The high calcium concentration grabs onto sensors on tiny vesicles filled with neurotransmitters, causing them to burst open and dump their chemicals into the gap between cells. This process happens the same way whether the neurotransmitter is GABA, glutamate, or acetylcholine.
