The brain-computer interface (bci) is a computer based system used in the field of medicine in order to correctly acquire brain signals so that the experts can analyze as well as translate them in the form of commands to perform a given action. Therefore bci doesn’t analyze on the basis of the normal output pathways of the brain which are peripheral nerves and muscles. it is a system which measures and uses the signals that are produced by the central nervous system. There is a common misconception among laymen that bci is capable of reading minds. The device will not extract information in an unwilling manner from the user. On the other hand, the bci enables users to perform desired actions by using brain signals instead of their muscles. Hence the bci and user tend to work in synchronization. After receiving training, the user is able to generate brain signals which encode intention. The bci later decodes these signals and translates into commands for an output device to fulfill the user’s intention.
in a research study led by Charles Lieber, a professor of Chemistry, the group presented a demonstration in which syringe-injectable mesh electronics could record neural activity in a stable manner among mice for the span of more than eight months. Lieber stated that if humans develop the ability to follow a set of individual neurons in a circuit chronically, it could open up an array of options.
