The mouse tends to pull the tongue to an unconscious colleague.
Wenjian Sun et al. 2025
When they discover another unconscious mouse, some mice seem to be trying to revive their companions by crouching and biting them, pulling their tongs to the side to clean the prayer. Discovery is a hint that treatment behavior can be more common in the animal kingdom than we thought.
There is a rare report on the following large social mammals. The harsh chimpanzy touches and licks an injured colleague,,, Dolphin tries to breathe by pushing the podmate worrying to the surface. and The elephant helps relatives.
now, Li Zhang At the University of Southern California (USC), his colleagues filmed what happened when he presented a familiar cage mate that was activated or anesthesized and reacted in the laboratory mouse.
In a series of tests, on average, animals have dedicated about 47 %of the 13 -minute observation window to interact with unconscious partners, showing three kinds of actions.
Zhang said, “They sniff and start with trimming, then start with very intensive or physical interactions. “They really open this animal’s mouth and take out the tongue.”
This more physical interaction was licking my eyes and biting my mouth. After focusing on the mouth, the mouse pulled the tongue of a partner that did not respond in more than 50 % of cases.
In a separate test, the researchers gently placed non -toxic plastic balls in the unconscious mouse’s mouth. In the case of 80 %, the helping mouse successfully removed the object.
Team members say, “If you extend the observation window, the success rate can be much higher.” Huizhong TAOEven in USC.
The mouse that attended woke up and began to walk faster than the endless thing about the mouse, and once he reacted with movement, the caregiver mouse slowed down and stopped caring behavior.
The caring mouse also spent more time on unconscious mouse if he was familiar than he had never met before.
Zhang said that recovery behavior is not an analog of CPR and not a CPR that requires expert training. It is similar to using salt or slabs with strong smells to wake someone or perform basic first aid so that unconscious people can breathe. He said that it is important not to block the prayer during surgery by placing the anesthetic tongue, he said.
Zhang and his colleagues found that behavior was led by oxytocin release neurons in the brain’s amygdala and hypothalamic areas. Hormone oxytocin is involved in other caring behaviors across extensive vertebrates.
Similar actions are reported in the laboratory mouse. Combined Research Thesis It was also explained by other teams By the third team of last month.
“I have never observed this type of behavior when I executed the experiment in the laboratory, but I did not have an animal that restores until the partner is completely awake.” Christina Marakez At the Neuroscience and Cell Biology Center of Portugal Coembra. “The fact that three independent laboratorys observed similar behaviors indicates that this is a powerful discovery. However, we must be really careful about observing or observing or more than observed in non -human species. ”
Zhang and his colleagues think that behavior is more natural than learning. All of the animals tested partially were two to three months, and they did not see this behavior or anesthetic cage mate.
He suggests that such instinct behavior plays an important role in improving group cohesion and can be more widely among social animals than ever before.
Márquesz says that it can be difficult to see these actions in wild mice. “Mouse is often a food animal that doesn’t live in a big group, so we usually hide it from our human beings. but [the fact] Just because we don’t see it doesn’t mean they don’t do it. ”
