Brain-Computer Interfaces: From Past to Future | Biomed grid

More than 100 years ago, scientists were interested in the capabilities of the brain and tried to understand whether it is possible to somehow influence it. In 1875, English doctor Richard Caton managed to register a weak electric field on the surface of the brain of rabbits and monkeys. Then there was a lot of discovery and research, but only in 1950, José Manuel Rodríguez Delgado, a professor of physiology at Yale University, invented the device, which could be implanted in the brain and controlled by radio signals. Thus, began the era of neural interfaces and technologies capable of enhancing human biological capabilities. Already in 1972, a cochlear implant went on sale, which converted the sound into an electrical signal, transmitted it to the brain and actually allowed people with severe hearing impairments to hear. Moreover, in 1973, for the first time, the term “brain-computer interface” was used - a computer-based neuro interface
