Mice is identical to the image of the beast disgusting and should be avoided. However, in terms of social behavior, these rodents have empathy like humans.
Neuroscience researcher from Netherlands Institute for Neuroscience, Amsterdam, Christian Keysers, preparing experiments to test this. Every day for an hour, he was locked in a cage a rat in a transparent and release the other rats in the vicinity. Through experiments, the response of mice Keysers can find out when he saw his friend suffer.
Initially, the rats chose to run around the cage, then tried to bite and make a breach. After seven days, the business exemption has increased. Free mice started to learn to open the cage door.
"It was clear that the effort is intentional," said Ben-Ami Bartal, a psychologist from the University of Chicago who participated in this study. "Rats are free to approach the door and opened it."
This release step is terminated full sprint action as the flood of happy madness.
In experiments that involved dozens of pairs of mice was also known that 5 of 40 mice also opened the cage empty. If the cage containing the mice, as many as 23 of 30 mice could open the door. Meanwhile, if the cage contains other animals, the tendency of mice to open the door no better than the empty cage.
Researchers also made two cages, each containing a rat and a bar of chocolate, so the mice are free to choose. The results were surprising. Mice have the same desire in terms of freeing a friend or eat chocolate. Thus, for mice, freeing your friends to enjoy the delights as sweet a bar of chocolate.
Surprises do not end there. "It turns leaves brown mice to other mice," Bartal said. This case occurs in about half of the release events. *** [SCIENCENEWS | ANTON WILLIAM | KORAN TEMPO 3773]
