Mphindi makumi atatu zimateteza ubongo wanu kwa moyo wonse

Kafukufukuyu adachitidwa ndi ofufuza a ku American University of Maryland, ndipo zotsatira zawo zidasindikizidwa m'magazini yaposachedwa ya Scientific Journal of the International Neuropsychological Society.

Kuti afikire zomwe adapeza, ofufuzawo anayeza zomwe zimachitika muubongo pogwiritsa ntchito fMRI ya omwe adatenga nawo gawo athanzi azaka zapakati pa 55 mpaka 85.

Gululi linapemphanso ophunzira kuti azichita ntchito zokumbukira zomwe zimaphatikizapo kuzindikira mayina otchuka komanso osadziwika.

Malinga ndi kafukufukuyu, njira yokumbukira mayina otchuka imayambitsa neural network yokhudzana ndi kukumbukira kwa semantic, yomwe imadziwika kuti imawonongeka pakapita nthawi chifukwa cha kuchepa kwa kukumbukira kwa okalamba.

Mayeserowa anachitidwa maminiti a 30 pambuyo pochita masewera olimbitsa thupi kwambiri pa bicycle yochita masewera olimbitsa thupi, ndiyeno adathamanga mayesero omwewo koma pa tsiku lopuma pamene ophunzira sanachite masewera olimbitsa thupi.

Ofufuzawa adapeza kuti masewera olimbitsa thupi adayambitsa ubongo m'magawo a 4 cortical omwe amakumbukira kukumbukira, omwe amadziwika kwambiri ndi "hippocampus" - omwe amagwira ntchito kuti aphatikizire ndikupeza zambiri zikafunika - poyerekeza ndi kupuma.

Ofufuzawo adawonetsa kuti hippocampus imachepa ndi zaka ndipo dera laubongo limakhala ndi mapuloteni owopsa omwe amatsogolera ku matenda a Alzheimer's.

"Kafukufuku wam'mbuyomu wasonyeza kuti kuchita masewera olimbitsa thupi nthawi zonse kungapangitse kuchuluka kwa hippocampus, koma phunziro lathu limapereka chidziwitso chatsopano chakuti kuchita masewera olimbitsa thupi kwambiri kumatha kukhudza mbali yofunika kwambiri ya ubongo," anatero wofufuza wamkulu Carson Smith.

"Monga momwe minofu imathandizira kuchita masewera olimbitsa thupi mobwerezabwereza, masewera olimbitsa thupi amodzi amatha kupititsa patsogolo maukonde a ubongo m'njira zomwe zimapangitsa kuti azitha kukalamba, kuwonjezera kukhulupirika kwa maukonde ndi ntchito, komanso kulola kuti azitha kukumbukira bwino."

Matenda a Alzheimer's ndi mtundu wofala kwambiri wa dementia, ndipo umabweretsa kufooka kosalekeza kwa luso la kulingalira ndi kugwira ntchito kwa ubongo, ndi kuiwala kukumbukira. Matendawa akupita patsogolo pang'onopang'ono mpaka kutaya mphamvu zogwirira ntchito za tsiku ndi tsiku, komanso kulankhulana ndi chilengedwe, ndipo vutoli likhoza kuwonongeka mpaka kusowa kwa ntchito.
