A group of scientists from Germany found that rats are able to play group games for fun. The study is published in the journal Science.
Experts have managed to teach them to play hide and seek six rats at the age from 5 to 23 weeks. First, they were motivated by treats, but when the researchers stopped giving the treats rodents, they continued to play. All this time, the researchers observed the processes occurring in the head of animals.
In the result, the rats have mastered the rules of the game for two weeks — every time they were hiding in a new place and quickly found people.
In may last year, the Indiana University neuroscientists in the US have shown that rats are capable of higher nervous activity, characteristic to humans. It was noted that rodents can remember the past events in chronological order.
In the course of the study, we used 13 rats, which were trained to memorize a list of 12 different odors. On average, animals were successfully 87 percent of the tests, which confirmed that they have episodic memory, which contains information about events that are in a specific order.
