A unique experiment rats restored their sense of orientation in space.
Researchers Hiroaki Norimoto and Yuji Ikegaya at the University of Tokyo used a geomagnetic prosthesis to restore some order rats. The device sends information about the surrounding area directly in rodent brain.
Researchers aim was to restore order to orient blind rats by stimulating the visual cortex of the brain. To achieve this, they built a sensor connected to a digital compass microsimulator two electrodes.
Once the device is connected to the visual cortex that detects geomagnetic head position and sends signals that tell which way is north rat or south, for example.
Blind Mice were taught by the device to look for food in different mazes and after a few attempts the animals have learned to use information from the device to exit the maze. Navigation strategies and performance of the blind mice were similar to those of healthy mice.
"The most remarkable thing of this study is that it shows potential or latent abilities of the brain. Specifically, we have shown that, in mammals, the brain is flexible even in adulthood - enough to acquire a new experience that was not inherited, the sources of background ", noted Ikegaya.
The play could sense orientation and blind people.
"You can not use your full brain. This limitation is caused by a lack of effort, but the weakness of the sense organs of the body. True sensory world must be more colorful << >> than what we experience now, "says Japanese researcher.
