Kungakhathaliseki ukuthi uzivocavoca ejimini noma ugibele ibhayisikili lakho ngaphandle, leso sikhathi esisabekayo sokukhathala, lapho ubonakala ungakwazi ukudlula kuso, uzizwa ngendlela efanayo. Kuvela ukuthi ingxenye yalokho kukhathala ingase ibe sekhanda lakho. Futhi ukwazi kahle ukuthi kwenzeka kuphi ebuchosheni kungadala izindlela zokwelapha ezithuthukisa ukusebenza esikhathini esizayo, ngokusho kocwaningo. ucwaningo lwakamuva ku-Nature Communications.
Abacwaningi bafake abahlanganyeli bocwaningo abangu-20 futhi babacela ukuthi babambe ngokuphindaphindiwe futhi bacindezele inzwa, beshintsha izinga labo lomzamo ukusuka emandleni amancane ukuya kwamakhulu. Besebenzisa idatha evela kuma-MRIs namamodeli wekhompyutha, bathole lokho imizwa yokukhathala ibonakala ivela ku-motor cortex, indawo yobuchopho enesibopho sokulawula ukunyakaza, ngokusho kocwaningo lombhali uVikram Chib.
Njengesinyathelo esengeziwe sokunquma ukuthi lokhu kuthinta kanjani ukusebenza kobuchopho, abacwaningi banikeze ababambiqhaza izinketho ezimbili zokuthi baqhubeke. Okukodwa kwakubhekwa "njengengozi," kusetha inani lomzamo ngokusekelwe ekuphonseni uhlamvu lwemali olunikeza ithuba lokungenzi mzamo noma izinga lomzamo elinqunywe kusengaphambili. Inketho "ephephile" bekuyizinga elizenzakalelayo.
Ngokwethula ukungaqiniseki, abacwaningi bakwazi ukubona ukuthi umhlanganyeli ngamunye uwazisa kangakanani umzamo wabo. Lokho kwanikeza ukuqonda kokuthi abantu bangakhetha ukuqhubeka, noma bekhathele.
Ukukhathala kuzithinta kanjani izinqumo zethu?
Ngokungangabazeki, abacwaningi bathola ukuthi abantu bavame ukuba sengozini enkulu yokugwema ukuzikhandla. Bonke ngaphandle koyedwa wabahlanganyeli bakhethe inketho ephephile, futhi izikena zabonisa ukuthi kubo bonke, i-motor cortex yayivaliwe ngesikhathi sokuthatha izinqumo.
Lokhu kuhambisana nezifundo zangaphambilini ezikhombisa ukuthi uma abantu bekhathala, umsebenzi we-motor cortex uyancipha, okungaholela ekuthumeleni amasignali ambalwa emisipha, okuholela ekunciphiseni kwamandla ngesikhathi sokugijima kanzima, isibonelo.
Ngabe le miphumela izoholela kulokhu likaHack yilelo elaligqokwe i-motor cortex ukuze ukungqongqoza kube yinto yesikhathi esidlule? Hhayi okwamanje, kodwa akunakwenzeka futhi.
Ososayensi bakholelwa ukuthi singasebenzisa ubuchopho obungahlanyisi ukuqondisa umsebenzi we-motor cortex nokulindelwe ukusebenza komuntu ngamunye. Okunye esingakwenza ukwethula amasu okuqonda angakwazi ukuwenza abantu bashintsha indlela ababona ngayo umzamo, futhi lokhu kungaba nomthelela ekusebenzeni kwe-motor cortical futhi kwenze imizamo izizwe ingakhathali.
