15. Tongue-to-Brain Circuit: The Fast Track
A companion study in Science Advances unveiled a direct tongue-to-brain neural circuit responsible for the rapid arousal seen in rescued mice.
When the tongue is stimulated—by a fellow mouse’s pulling, for instance—this circuit sends immediate signals to the brain’s arousal centers, jumpstarting the recovery process from anesthesia.
This elegant biological shortcut explains how such targeted, physical rescue efforts can deliver almost instant results, turning the tongue into a lifeline for unconscious animals.
