Mice perform first-aid on unconscious companions, study finds

Researchers have found that mice exhibit first-aid behaviors towards unconscious companions. They lick faces and pull at tongues, with more vigorous actions leading to quicker recovery. This behavior is more intense among familiar mice. The study, published in Science, shows that mice can recognize when a partner is unconscious, even in the dark. They spend significant time interacting with the unconscious mouse, and the intensity of grooming increases over time. The grooming behavior is linked to the release of oxytocin, a hormone associated with social bonding. Future research will explore the specific brain circuits involved in this instinctive response.
