Odwala ALS amatha kulankhulana ndi maganizo awo

Amyotrophic lateral sclerosis (ALS) ndi matenda omwe amadziwika ndi kuwonongeka kwa maselo a minyewa, zomwe zimapangitsa kuti munthu alephere kulamulira thupi. Izi zimapangitsa odwala ambiri kukhala olumala komanso osalankhula. Odwala ambiri a ALS amadalira zida zotsata maso kuti azilankhulana ndi ena. Komabe, machitidwewa siwothandiza kwambiri chifukwa amafunikira kukonzanso tsiku ndi tsiku ndi mainjiniya. Pamwamba pa izi, 1 kuchokera 3 Odwala a ALS pamapeto pake amalephera kuwongolera kayendetsedwe ka maso, kupangitsa zida zamtunduwu kukhala zopanda ntchito ndikusiya odwala "otsekeredwa".

Ukadaulo wopita patsogolo

Izi zonse zidasintha ndi Hanneke De Bruijne, mayi wazaka 58 yemwe kale anali dokotala wamankhwala amkati ku Netherlands. Adapezeka ndi ALS mu 2008, monga ena ambiri omwe ali ndi matendawa, De Bruijne m'mbuyomu adadalira zida zolondolera maso izi koma makina ake atsopano adakulitsa moyo wake. Patapita zaka ziwiri, De Bruijne anali “pafupifupi kutsekeredwa mkati” malinga ndi a Nick Ramsey ku Brain Center ya University Medical Center Utrecht ku Netherlands, ngakhale kudalira makina olowera mpweya kuti azitha kupuma. 

Anakhala wodwala woyamba kugwiritsa ntchito chipangizo chapanyumba chatsopano chomwe chimamuthandiza kuwongolera chida chakompyuta ndi malingaliro ake. Ma electrode awiri adachitidwa opaleshoni kuikidwa mu ubongo wa De Bruijne m'dera la motor cortex. Ma implants atsopano muubongo amawerenga ma siginecha amagetsi kuchokera muubongo ndipo amatha kumaliza ntchito za De Bruijne kudzera polumikizana ndi electrode ina yomwe idayikidwa pachifuwa cha De Bruijne. Izi zimachitika kudzera m'miyendo ya robotic, kapena kompyuta. Pa tabuleti yolumikizidwa pampando wake akhoza kulamulira kusankha kalata pazenera ndi maganizo ake ndipo akhoza kutchula mawu kulankhula ndi amene ali pafupi naye.

Pakali pano ndondomeko pang'onopang'ono, za 2-3 mawu miniti, koma Ramsey akulosera kuti powonjezera maelekitirodi ambiri akhoza kufulumizitsa ndondomekoyi. Powonjezera ma electrode 30-60, amatha kuphatikizira mtundu wina wa chilankhulo chamanja, chomwe chingakhale njira yachangu komanso yosavuta yomasulira malingaliro a De Bruijne.
