rats are pretty smart. You can recognize items, specific press and overcome obstacles. In 2005, a rat caused a stir, because she managed to hide for more than four months before the biologists on a new Zealand island. The scientists exposed the animals there and wanted to catch it after experiments with a tracker again. However, the animal escaped from the biologists and even swam 400 meters to the neighboring island. Now American neuro-scientists have taught several lab rats driving the car, as they report in the journal Behavioural Brain Research.
a Team led by Kelly Lambert of the University of Richmond got 17 Long-Evans rats to a purpose-built vehicle and they left it to a Liquid at the other end of a training square. The black-and-were animals white pulled in a cage with employment opportunities, such as pine cones, or plastic balls, large, mastered this complex task without any problems.
rats with and without employment opportunities
rats, who grew up in a normal laboratory cage, deeds heavier; in addition, they showed significantly less interest in it, to learn how to Drive at all. Lambert and her colleagues were practicing three times a week with their protégés for five minutes. They motivated the rats to cover longer distances, by increased the distance between the Start point and the end point piece by piece. After eight weeks of Training the animals were able to travel a distance of up to 1.40 meters, with the car – and not only straight ahead, but included more complex maneuvers.
The vehicle consisted of a transparent plastic box on a robot with four wheels. In the Box, which served as the driver’s cottage, cut the researchers a window and clamped with copper wires. In addition, they placed an aluminum plate on the bottom of the cab. The rats were on the plate and touched one of the copper wires with their paws, los castle a circuit and the car drove. Depending on the position at which the animals touched the wires, moving it to the left, right or straight ahead.
on the Basis of the animal excreta, the neuro-scientists were able to investigate the hormonal balance of the moving rats. Obviously, the animals are by regular jaunts to be more relaxed – but only if you pay yourself the car sat the rats in a remote-controlled car, not the effect. Therefore, Lambert and her Team suspect that the driving training makes the animals more resistant to Stress.
