Neuroscientist Luc Miller from the University of Lyon in France, in the course of a recent study, proved that the human body has a developed ability to supersensorize. In particular, he demonstrated that we can not only feel the touch of objects on our skin, but also react to the contact of these objects with other people.
This phenomenon in various forms has been known for a long time, but Miller's merit is that he studied the course of the process in the human brain. During 400 experiments, the subjects held wooden sticks and tried, without looking, to determine where the laboratory assistant touches their sticks with another stick. And although the difference in contact points was only a few mm, the accuracy of the answers reached 96%.
The data from the electroencephalogram showed amazing things - the brains of the subjects worked in a normal mode, the same processes took place in it as when they touched the skin. That is, the nervous system, as it were, made the rod an extension of itself, its additional sensor. Computer simulations have shown that it takes only 20 milliseconds for the brain to respond to vibrations generated in the stick when it comes into contact with another object.
Analyzing the results of the study, Miller's team concluded that they had found some important evolutionary tool. A person can not only use objects as an extension of the sense organs, he also has adapted to hold and use them so that it is more convenient to read signals. Now scientists hope that their development will serve the development of prostheses. Thanks to them, artificial limbs will receive the functions of sensors and will be able to transmit information about the environment as well as living parts of the body.
