Intermittent Vibration Induces Sleep via an Allatostatin A‐GABA Signaling Pathway and Provides Broad Benefits in Alzheimer's Disease Models

While animals across species typically experience suppressed consciousness and an increased arousal threshold during sleep, the responsiveness to specific sensory inputs persists. Previous studies have demonstrated that rhythmic and continuous vibration can enhance sleep in both animals and humans. However, the neural circuits underlying vibration-induced sleep (VIS) and its potential therapeutic benefits on neuropathological processes in disease models remain unclear. Here, it is shown that intermittent vibration, such as cycles of 30 s on followed by 30 s off, is more effective in inducing sleep compared to continuous vibration. A clear evidence is further provided that allatostatin A (AstA)-GABA signaling mediates short-term intermittent vibration-induced sleep (iVIS) by inhibiting octopaminergic arousal neurons through activating GABA
