Akatswiri azachipembedzo apeza umboni wamphamvu kuti kukumbukira momveka bwino komanso kuwonekera mwachindunji panthawi yeniyeniyo kumatha kuyambitsa zochitika zofananira za ubongo.
Kafukufukuyu, motsogozedwa ndi Rotman Research Institute (RRI) ya Baycrest, mogwirizana ndi University of Texas ku Dallas, ndi amodzi mwamphamvu kwambiri komanso ovuta kwambiri kuwunikira kuthekera kwaubongo kutulutsa chikumbukiro poyambiranso magawo aubongo omwe anali wochita nawo chidziwitso choyambirira. Ofufuzawo adapeza kuti kukumbukira bwino komanso chidziwitso chenicheni chimafanana "modabwitsa" pamlingo wa neural, ngakhale sizofanana ndi "pixel-perfect" zaubongo.
Kafukufukuyu akuwoneka pa intaneti mwezi uno mu Journal of Cognitive Neuroscience, asanafike osindikiza.
Dr. Brad Buchsbaum, wofufuza wamkulu komanso wasayansi wa RRI ya Baycrest adati: "Tikamakumbukiranso zomwe tidakumana nazo, zitha kumva kuti tabwerera m'mbuyo ndikukhalanso ndi moyo nthawi yomweyo." "Kafukufuku wathu watsimikizira kuti kukumbukira kovuta, kosiyanasiyana komwe kumakhudzana ndikubwezeretsa pang'ono gawo lonse la zochitika zaubongo zomwe zimatulutsidwa pakuwona koyambirira kwa zomwe zidachitikazo. Izi zimathandiza kumvetsetsa chifukwa chake kukumbukira bwino kungakhale kwenikweni. ”
Koma kukumbukira bwino sikumatipusitsa kukhulupirira kuti tili mdziko lenileni, lakunja - ndipo izi zokha zimapereka chidziwitso champhamvu kuti magwiridwe antchito awiriwa sagwira ntchito chimodzimodzi muubongo, adalongosola.
Phunziroli, gulu la Dr. Buchsbaum lidagwiritsa ntchito maginito opanga maginito (fMRI), ukadaulo wamphamvu wopanga maubongo womwe umapanga zithunzi zapa kompyuta za madera aubongo omwe amagwira ntchito munthu akamachita zinazake zanzeru. Gulu la achikulire athanzi 20 (azaka zapakati pa 18 mpaka 36) adasanthulidwa pomwe amawonera makanema 12, masekondi aliwonse asanu ndi anayi kutalika kwake, ochokera ku YouTube.com ndi Vimeo.com. Zithunzizo zinali ndizosiyanasiyana - monga nyimbo, nkhope, malingaliro amunthu, nyama, ndi mawonekedwe akunja. Ophunzira adalangizidwa kuti azisamala kwambiri ndi makanema aliwonse (omwe amabwerezedwa kangapo 27) ndikudziwitsidwa kuti ayesedwa pazomwe zili m'mavidiyo pambuyo pa sikani.
Gulu laling'ono la anthu asanu ndi anayi ochokera ku gulu loyambalo adasankhidwa kuti amalize kulimbitsa kwakanthawi ndikulinganiza sabata zingapo zomwe zimafuna kuti azichita mobwerezabwereza makanema obwereza omwe adawonera kuchokera gawo loyamba. Maphunzirowa atatha, gululi linasungidwanso pamene anali kulowetsa video iliyonse. Kuti apangitse kukumbukira kwawo kanema, iwo anaphunzitsidwa kuphatikiza chifanizo chilichonse. Kutsatira kubwereza kwamaganizidwe kulikonse, ophunzira amatenga batani lakuwonetsa pa 1 mpaka 4 (1 = kukumbukira kusakhala bwino, 4 = kukumbukira bwino) momwe adaganizira kuti adakumbukira chidutswa china.
Gulu la a Dr. Buchsbaum lidapeza "umboni wowoneka bwino" wosonyeza kuti magawidwe ogwiritsira ntchito ubongo mwa kukumbukira bwino amatsanzira zomwe zimachitika pakuwona kwamakanema pomwe makanemawo amawonedwa - ndi makalata a 91% pambuyo pofufuza zonse zomwe zachitika pa fMRI.
Zomwe zimatchedwa "malo otentha", kapena kufanana kwakukulu kwambiri, zidachitika m'malo ophatikizira komanso oyanjana ndi magalimoto a cerebral cortex - dera lomwe limachita gawo lalikulu pakukumbukira, chidwi, kuzindikira, kulingalira, chilankhulo komanso kuzindikira.
Dr. Buchsbaum adanenanso kuti kusanthula kulingalira komwe kwagwiritsidwa ntchito mu kafukufuku wake kumatha kuwonjezera pazida zamakono zowunikira kukumbukira zomwe madokotala amatha. Njira zogwiritsa ntchito ubongo kuchokera ku fMRI zitha kupereka njira yodziwira ngati lipoti la wodwalayo la kukumbukira kwawo kuti "kukhala wabwino kapena wowoneka bwino" ndilolondola kapena ayi.
