Kuika Ubongo Kungathandize ndi ALS Paralysis

Chipangizo chofufuzira chomwe chimatchedwa mawonekedwe a ubongo-kompyuta chapezeka kuti chili chotetezeka mu kafukufuku wochepa wa anthu olumala kuchokera ku ALS, ndipo walola ophunzira kugwiritsa ntchito kompyuta kuti azilankhulana ndi malemba ndikuchita ntchito za tsiku ndi tsiku monga kugula pa intaneti ndi kubanki, malinga ndi a Phunziro loyambirira lomwe latulutsidwa lero, Marichi 29, 2022, lomwe lidzakambidwe pa Msonkhano Wapachaka wa American Academy of Neurology womwe ukuchitikira panokha ku Seattle, Epulo 74 mpaka 2, 7 ndipo pafupifupi, Epulo 2022 mpaka 24, 26.

ALS ndi matenda opita patsogolo okhudza ubongo omwe amakhudza ma cell a mitsempha muubongo ndi msana. Anthu omwe ali ndi ALS amalephera kuyambitsa ndi kulamulira kayendedwe ka minofu, zomwe nthawi zambiri zimabweretsa kufa ziwalo zonse.

"Anthu omwe ali ndi ALS pamapeto pake amatha kusuntha miyendo yawo, zomwe zimawapangitsa kuti azilephera kugwiritsa ntchito zipangizo monga foni kapena kompyuta," anatero wolemba kafukufuku Bruce Campbell, MD, MS, wa pa yunivesite ya Melbourne ku Australia komanso membala wa American Academy. mu Neurology. “Kafukufuku wathu ndi wosangalatsa chifukwa ngakhale zida zina zimafunikira opaleshoni yomwe imaphatikizapo kutsegula chigaza, chipangizochi cholumikizira ubongo ndi kompyuta sichimasokoneza. Imalandira mauthenga amagetsi kuchokera ku ubongo, zomwe zimathandiza anthu kulamulira kompyuta ndi maganizo. "

Pa kafukufukuyu, anthu anayi omwe ali ndi ALS adachitapo kanthu kuti chipangizocho chiyike mu ubongo. Mawonekedwe a ubongo ndi makompyuta amadyetsedwa kudzera m'mitsempha iwiri ya jugular m'khosi kupita mumtsempha waukulu wamagazi muubongo. Chipangizocho, chopangidwa ndi zinthu ngati ukonde chokhala ndi masensa 16 olumikizidwa, chimakula kuti chigwirizane ndi khoma la chotengeracho. Chipangizocho chimalumikizidwa ndi chipangizo chamagetsi chomwe chili pachifuwa chomwe chimatumiza mauthenga a muubongo kuchokera ku motor cortex, mbali ya ubongo yomwe imatulutsa zidziwitso zakuyenda, kukhala malamulo a laputopu.

Ochita kafukufuku adayang'anitsitsa ochita nawo kwa chaka chimodzi ndipo adapeza kuti chipangizocho chinali chotetezeka. Panalibe zochitika zowopsa zomwe zinapangitsa kulumala kapena imfa. Chipangizocho chinakhalanso m’malo mwa anthu onse anayi ndipo mtsempha wa magazi umene anaikamo chipangizocho unakhalabe wotsegula.

Ochita kafukufuku adawonanso ngati otenga nawo mbali angagwiritse ntchito mawonekedwe aubongo-kompyuta kuti achite ntchito zama digito. Onse omwe adatenga nawo mbali adaphunzira kugwiritsa ntchito chipangizocho poyang'anira maso pogwiritsa ntchito kompyuta. Ukatswiri wofufuza ndi maso umathandizira kompyuta kudziwa zomwe munthu akuyang'ana. 

Ofufuza anenanso kuti decoder yomwe idapangidwa panthawi ya kafukufukuyu idalola wophunzira m'modzi kuti aziwongolera kompyuta popanda cholondera chamaso. Decoder yophunzirira makina idakonzedwa motere: wophunzitsa atapempha ophunzira kuti ayese mayendedwe ena, monga kugunda phazi lawo kapena kukulitsa bondo, decoder idasanthula ma cell a mitsempha kuchokera kumayendedwe awo. Decoder idatha kumasulira ma signature mumayendedwe apakompyuta.

"Kafukufuku wathu akadali watsopano, koma ali ndi lonjezo lalikulu kwa anthu olumala omwe akufuna kukhala ndi ufulu wodzilamulira," adatero Campbell. "Tikupitiriza kafukufukuyu ku Australia komanso ku United States m'magulu akuluakulu a anthu."
