A new study suggests that lab mice display innate behaviors aimed at reviving unconscious cagemates. When researchers anesthetized mice, their active cagemates engaged in social interactions, escalating from gentle sniffing to more assertive actions like tongue biting and pulling. These behaviors were effective in helping the unconscious mice regain consciousness, as they expanded airways and dislodged foreign objects placed in their mouths. Notably, familiar mice were more likely to assist each other, indicating that familiarity plays an essential role in these revival efforts.
Then we noticed, OK, its cagemate has shown very strong social interaction with this anesthetized partner.
So it seems that the mouse can perform deliberately this whole set of behaviors, escalating from sniffing, grooming, to more forceful actions.
When mice pulled out the tongues of their cagemates, that actually expanded the airways of the unconscious mouse.
Familiarity is a very important factor, so it plays the major role.
