Brain-com­puter In­ter­face

Technowize Magazine - - Futurist -

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.
