Mechanistic description

40 Hz stimulation triggers G-protein-coupled receptor (P2Y1) signaling in astrocytes, normalizing intracellular Ca2+ dynamics and opening Cx43 hemichannels to release lactate and D-serine. This supports neuronal energy demands and NMDA receptor co-agonism during synchrony events. This is the most nascent mechanism with the least direct causal evidence. Astrocyte calcium events are phase-locked to gamma (Caccavano 2020) but whether this is a driver vs. a consequence of entrainment is unclear.
