Scientists have discovered the unique ability of laboratory rats.
During a series of experiments, it was possible to find out that rats can play hide and seek and even enjoy it.
Neuroscientists at Humboldt University in Berlin are of the opinion that all living things have a tendency to play and that it is this entertaining process that maximally trains the brain.
In an experiment with laboratory rats, scientists found that rats made ultrasonic sounds, similar to "giggles," when they were tickled.
The experiment itself turned out to be unique, because a simple at first glance game of hide and seek is a rather complex game that requires an understanding of the rules and a clear understanding of the role of players in various situations.
