Kodi mukufuna kukumbukira bwino? Mugone mokwanira! Kupatula apo, gawo la kugona kwa REM (gawo la REM, pomwe maloto amawonekera ndikuyenda kwamaso mwachangu) kumakhudzidwa ndikupanga kukumbukira. Asayansi anenapo izi kangapo, koma posachedwapa zakhala zikuchitika kuti zitsimikizire kuti ntchito za ma neuron omwe amachititsa kuti mudziwe zambiri kuchokera kwakanthawi kochepa mpaka kukumbukira kwakanthawi ndikofunikira kwambiri munthawi yogona ya REM. Asayansi ku Yunivesite ya Bern ndi Douglas Institute of Mental Health ku McGill University apeza izi, zomwe zikuwonetsanso kufunikira kwa kugona mokwanira. Zotsatira za kafukufuku wawo zidasindikizidwa mu nyuzipepala ya Science, portal Neurotechnology.rf imalemba mwatsatanetsatane za izi.
Chidziwitso chilichonse chongopezeka kumene chimasungidwa m'mitundu yosiyanasiyana ya kukumbukira, mwachitsanzo, malo okhalamo kapena malingaliro, ndipo pokhapokha chimaphatikizidwa kapena kuphatikizidwa, kuchoka kwakanthawi kochepa mpaka nthawi yayitali. “Momwe ubongo umagwirira ntchito imeneyi sikunadziwikebe mpaka pano. Kwa nthawi yoyamba, tidakwanitsa kutsimikizira kuti kugona kwa REM ndikofunikira kwambiri pakupanga kukumbukira kwa mbewa, "akufotokoza m'modzi mwa omwe adalemba kafukufukuyu, Sylvain Williams.
Kuti achite izi, asayansi adachita zoyeserera pa mbewa: makoswe omwe anali mgululi ankaloledwa kugona mwachizolowezi, ndipo mbewa pagulu loyeserera panthawi yogona ya REM "zimazimitsa" ma neuron omwe amachititsa kukumbukira, kuwachita ndi zikopa zopepuka. Pambuyo pakuwonekera kotere, mbewa izi sizinazindikire zinthu zomwe adaphunzira kale, ngati kuti kukumbukira kwawo kudachotsedwa.
Ndipo apa pali mfundo yofunika kwambiri, yomwe wolemba wamkulu wa kafukufukuyu, Richard Boyes anati: "Kuzimitsa ma neuron omwewo, koma kunja kwa zigawo za kugona kwa REM, sikunakhudze chilichonse pokumbukira. Izi zikutanthauza kuti zochitika za neuronal panthawi yogona REM ndizofunikira pakuphatikizika kwakumbukiro. ”
Kugona kwa REM kumawerengedwa kuti ndi gawo lofunikira kwambiri pakazungulira tulo ta nyama zonse, kuphatikiza anthu. Asayansi akuwonjeza kuti kusakhazikika kwake kumawoneka ndimatenda osiyanasiyana aubongo monga Alzheimer's kapena Parkinson. Makamaka, kugona kwa REM nthawi zambiri kumasokonekera kwambiri mu matenda a Alzheimer's, ndipo zotsatira za kafukufukuyu zikuwonetsa kuti kuwonongeka koteroko kumatha kukhudza kuwonongeka kwa kukumbukira kwa "Alzheimer's", ofufuzawo akuti.
Kuti thupi lizigwiritsa ntchito nthawi yomwe limafunikira mu gawo la REM, yesetsani kugona mosalekeza kwa maola 8: ngati kugona kumasokonezedwa pafupipafupi, ubongo umakhala nthawi yocheperako.
Mutha kuwerenga zambiri za kuyesa kosangalatsa kwa asayansi pansipa.

Mazana a maphunziro am'mbuyomu adayesapo kulephera kupatula zochitika za neural pogona atagwiritsa ntchito njira zoyeserera zachikhalidwe. Nthawi ino, asayansi adachita njira ina. Anagwiritsa ntchito njira yotsogola komanso yotchuka yotsogola pakati pa ma neurophysiologists, yomwe imawalola kudziwa molondola kuchuluka kwa ma neuron ndikuwongolera zochitika zawo mothandizidwa ndi kuwala.
Williams anati: "Tidasankha ma neuron omwe amayang'anira zochitika za hippocampus, kapangidwe kake kamene kamakumbukira pakudzuka, komanso makina a GPS aubongo," akutero Williams.
Poyesa kukumbukira kwakanthawi kwa mbewa, asayansi amaphunzitsa makoswe kuti azindikire chinthu chatsopano pamalo olamulidwa, pomwe panali kale chinthu chomwe adayesapo kale ndipo chimafanana ndi chatsopano chamtundu ndi voliyumu. Makoswe adakhala nthawi yayitali akufufuza "zachilendo", ndipo motero adawonetsa momwe kuphunzira kwawo ndi kukumbukira zomwe adaphunzira kale zikuchitika.
Mbewa izi zikagona mu REM, ofufuzawo amagwiritsa ntchito magetsi kuti azimitse ma neuron okhudzana ndi kukumbukira ndikuwona momwe izi zingakhudzire kuphatikiza kukumbukira. Tsiku lotsatira, makoswewa adalephera kwathunthu kugwiritsa ntchito kukumbukira kwa malo, osawonetsa ngakhale kachigawo kakang'ono kazomwe adalandira dzulo lake. Poyerekeza ndi gulu lolamulira, kukumbukira kwawo kumawoneka kuti kwachotsedwa.
