Nokuba usebenza kwindawo yokuzivocavoca okanye ukhwele ibhayisekile yakho ngaphandle, loo mzuzu woyikekayo wokudinwa, xa ungabonakali udlula kuwo, uziva ngokufanayo. Kuvela ukuba inxalenye yoko kukhathala ingaba entlokweni yakho. Kwaye ukwazi ngqo apho yenzeka khona kwingqondo kunokukhuthaza unyango oluphucula ukusebenza kwixesha elizayo, ngokutsho uphononongo lwakutsha nje kuNxibelelwano lweNdalo.
Abaphandi babhalise abathathi-nxaxheba be-20 kwaye babacela ukuba babambe ngokuphindaphindiweyo kwaye bacinezele inzwa, betshintsha inqanaba labo lomgudu ukusuka kumncinci ukuya kumandla amakhulu. Ukusebenzisa idatha evela kwi-MRIs kunye neemodeli zekhompyutheni, bafumene ukuba iimvakalelo zokudinwa zibonakala zivela kwi-motor cortex, indawo yengqondo enoxanduva lokulawula intshukumo, ngokutsho kombhali-mbhali uVikram Chib.
Njengomlinganiselo owongezelelweyo wokufumanisa ukuba oku kuchaphazela njani ukusebenza kwengqondo, abaphandi banikezela abathathi-nxaxheba ngeendlela ezimbini zokuqhubeka. Enye yayithathwa ngokuba "yingozi," ukubeka ubungakanani bomzamo osekelwe kwimali ephosayo enika ithuba lokungabi nanzame okanye inqanaba lokuzinza kwangaphambili. Ukhetho "olukhuselekileyo" yayilinqanaba elimiselweyo.
Ngokuzisa ukungaqiniseki, abaphandi baye bakwazi ukubona ukuba umthathi-nxaxheba ngamnye wawuxabisa kangakanani umzamo wabo. Oko kwanika ukuqonda malunga nokuba abantu banokukhetha ukuqhubeka, nokuba badiniwe.
Ukudinwa kuzichaphazela njani izigqibo zethu?
Ngokungathandabuzekiyo, abaphandi bafumanisa ukuba abantu bathambekele ekubeni sengozini ngakumbi ukuphepha ukuzibhokoxa. Bonke ngaphandle komnye wabathathi-nxaxheba bakhetha ukhetho olukhuselekileyo, kwaye izikena zabonisa ukuba kubo bonke, i-motor cortex yacinywa ngexesha lenkqubo yokwenza izigqibo.
Oku kuhambelana nezifundo zangaphambili ezibonisa ukuba xa abantu bedinwa, Umsebenzi we-motor cortex uyancipha, enokukhokelela ekuthumeleni imiqondiso embalwa kwizihlunu, ekhokelela ekunciphiseni amandla ngexesha lokuhamba nzima, umzekelo.
Ngaba ezi ziphumo ziya kukhokelela uqhekezo i-motor cortex ukuze ukunkqonkqoza kube yinto yexesha elidlulileyo? Hayi okwangoku, kodwa akunakwenzeka.
Izazinzulu zikholelwa ukuba sinokusebenzisa ukuvuselela kwengqondo okungaphazamisiyo ukulungelelanisa umsebenzi we-motor cortex kunye nolindelo lomsebenzi womntu. Enye into esinokuyenza kukwazisa amacebo okuqonda anokwenza abantu bayayitshintsha indlela abawubona ngayo umgudu, kwaye oku kunokuphembelela umsebenzi we-motor cortical kwaye yenze iinzame zizive zidiniwe.
