\nFor over 100 years, scientists have been interested in the capabilities of the brain and have attempted to understand whether it is possible to influence it in any way. In 1875, English doctor Richard Caton managed to record a weak electric field on the surface of the brains of rabbits and monkeys. There were many discoveries and studies afterward, but it was not until 1950 that Yale University physiology professor Jos\u00e9 Manuel Rodr\u00edguez Delgado invented a device called the 'Stimosiver', which could be implanted in the brain and controlled by radio signals.

\nThe experiments were conducted on monkeys and cats. For instance, stimulating a specific area of the brain through an implanted electrode made the cat lift its hind leg. According to Delgado, the animal showed no signs of discomfort during such experiments.<\/p>\n

\nThirteen years later, the scientist conducted a famous experiment<\/a><\/noindex> \u2014 he implanted stimosivers in the brain of a bull and controlled it via a portable transmitter.<\/p>\n

Thus began the era of neurointerfaces and technologies capable of enhancing human biological potential. As early as 1972, a cochlear implant was put on the market that converted sound into an electric signal, transmitting it to the brain and essentially allowing people with severe hearing impairments to hear. In 1973, the term 'brain-computer interface' was officially used for the first time. In 1998, scientist Philip Kennedy implanted the first neurointerface in a patient\u2014a musician named Johnny Ray. After a stroke, Johnny lost the ability to move. However, thanks to the implant, he learned to move the cursor by merely imagining the movement of his hands.<\/p>\n

Following the scientists, large business corporations and startups picked up the idea of creating neurointerfaces. Facebook and Elon Musk have already announced plans to develop a system that will help control objects through thought. Some harbor hopes for neurointerfaces\u2014these technologies will allow people with disabilities to regain lost functions and improve rehabilitation after a stroke or traumatic brain injury. Others are skeptical about such developments, believing that their use carries legal and ethical issues.<\/p>\n

Regardless, there are enough major players in the market. If we are to believe Wikipedia<\/a><\/noindex>, nogle udviklinger er allerede blevet taget af produktionen, men de andre er ret popul\u00e6re og tilg\u00e6ngelige.<\/p>\n

Hvad er et neurointerface, og hvordan kan det v\u00e6re nyttigt?<\/h2>\n

Neurointerface er et system til informationsudveksling mellem menneskets hjerne og en elektronisk enhed. Det er en teknologi, der muligg\u00f8r, at mennesket interagerer med omverdenen baseret p\u00e5 registrering af hjerneaktivitet \u2014 elektroencefalografi (EEG). Menneskets \u00f8nske om at udf\u00f8re en handling afspejles i \u00e6ndringer i EEG, som computeren derefter dekoder.
\nNeurointerfaces kan v\u00e6re ensrettede og tovejs. De f\u00f8rste modtager enten signaler fra hjernen eller sender dem til den. De sidstn\u00e6vnte kan b\u00e5de sende og modtage signaler samtidigt.
\nDer findes flere metoder til at m\u00e5le hjernesignaler. De opdeles i tre typer.<\/p>\n
