Brain - computer interface

Brain -computer interface - the interface that implements the connection between the human brain and the computer. The main idea is that when you think about action and do it, the same part of the brain is activated.In the middle of the XIX century, Emil Du Bois- Reymond showed the relationship between electric current and nerve impulses; in 1875. Richard ketone managed to register the electrical activity of the brain of animals. The psychiatrist Hans Berger in 1924 invented a method to record the electrical activity of the human brain. In 1967, psychiatrist Edmond Dewan published a paper in which he described the experiment where a man was trying to send a message to electroencephalogram by means of dot-and-dash,using brain activity.One of the first practically implemented IMC is considered a virtual keyboard made by Farwell and Donchyn which was created in 1988
