Revival with mouse mouse: rodents try to revive unconscious friends
Three studies show that a mouse will try to solve conscious consciousness
A mouse tries to get out of the language of a conortified social partner, perhaps to revive the air in an effort.

Mice in animated films and short movies make the oddest things Cooking Starred Plates to Steamboats piloting. But sometimes, real life imagines disney-esque. Consider the latest research that highlights the CPR mouse version. This study found that when the mice see a conscious conscious, it seems, aimed at rescuing friends, not all experts are convinced.
“Everything started from the unexpected observatory,” says Li Zhang, at the Keck School of University at the University of Southern California (USC). As they were doing laboratory experiments, Zhang and his colleagues noticed when a mouse encountered with a congestive partner, suddenly began to interact intensively.
“This put our attention because he has not reported before, in general, the animals respond to unconsciously unconscious,” Zhangek said. While the anecdotes of wild animals such as elephants, chimpanzees and dolphins, to help others with their need, to rescue behavior “never carefully examined.”

More probe, Zhang and his colleagues designed different experiments when he met the mouse with anesthesia with another mouse.
High resolution camera shot videos revealed that the first mouse had made a set of behavior with his unanswered partner. First, he sniffed the body of the unconscious mouse and then began to decorate the animal. Then he took a more vigorous action: biting his or her partner’s real estate mouth and pulled his tongue, cleaning the air opening. These actions are those who do human beings in first aid proceduresThe Group reports on a study published in February 21. When researchers put an object in the mouth of an unanswered mouse, the savior removed most of the time.
Then the team designed additional experiments to discourage whether this behavior was motivated by the unconscious desire, with unconscious mouse or curiosity. The results “We are really surprised,” Zhangek says. “We realized,” that is, this is it. “”
Mice are likely to disclose the behavior of the rescue rather than with strangers. On their part, women’s savings sometimes went along with strangers, compared to men, suggesting that they can have a higher level of empathy, researchers say. Savior of the mice did not experience any experience with an unconscious experience, suggesting that behavior is inherent.
The recipients of first aid behavior revived faster from the unconscious states, whether the researchers continue to be prudent to resignation. It is likely to evolve rescuer’s actions to improve the chances of animal survival, the author of Huizhong Tao’s studies, physiology and neuroscience teacher says USC medicine medicine in Keck School.
A closer look at the brains of these mice showed that the neuron in the hypothalamium that the hormone liberates the neuron in the expression of this first aid-like behavior, as Taok says.
Another study investigating the first mouse relief published in the same subject Science created similar results. Researchers found that The brain structure called Amygdala Medial is involved in the declaration of unconscious animals And when regulating the behavior of rescue. “These two different discoveries can complete each other,” suggesting that they can be necessary to support behaviors with unanswered assistants, “Taok said.
Another study published on January 22 in the advances in science, achieved similar effects He could participate in this behavior while highlighting another brain region.
“The behavior is very surprising,” says Ben-Ami Bartal, the Neuroscience of the University of Tel Aviv, helps to play in rats and not participating in new research. “For a long time, we wanted to explain that other behaviors are automatic or something that is achieved”. For example, human beings, Bartal says that many prosocial behaviors are culturally based on the skills of others.
This result, Bartal says, is another approach proposed by some scientists. In addition, we have an automatic circuit “Prosozially intended to play prosociary for others.”
“I think it’s important for humans,” it adds. “I think it realizes that it realizes that something is automatic in our promotment in our way.”
But not all scientists are convinced. “I totally agree with the interpretation,” says Peggy Mason, Professor of Neurobiology at the University of Chicago, also attended new research. While Okay, “rescue” indicates that mice are disturbed by their unanswered classmates, Mason believes that they are not really trying to rescue animals, but they are curious about them. “I think the behavior is okay,” he explained. “I think you’ve named it differently.”
In general, findings can be able to better understand the brain circuits that control new questions and more examinations. The brain paths that control these behaviors are clean, the authors say that the deficits of certain neurological disorders from Alzheimer’s author may appear.
