Pafupi munthu aliyense ali ndi zaka 50 akudwala mtundu wina wa kukumbukira. Nthawi zina kumakhala kosaiwalika, pamene mwadzidzidzi dzina la wotchuka wotchuka kapena dzina la filimu liiwalika. Koma izi zili kutali ndi matenda. Mitundu yotereyi ikumapezeka pafupifupi anthu onse. Matenda enieni okhudzana ndi kutaya kwa kukumbukira, monga lamulo, amabwera pambuyo pake. Ndipo amatchedwa matenda a Alzheimer's.
Imperceptible, kukalamba kwa ubongo kumayamba ndi kupanga mapangidwe ang'onoang'ono ndi makoswe kwa zaka makumi angapo isanayambe matendawa. Ntchito yokumbukila mwachizolowezi imaphatikizapo kuphunzira ndi kuloweza. Izi zimafuna ntchito yosadodometsedwa ya malo angapo a ubongo ndi maselo a ubongo mkati mwake. Selo iliyonse ya ubongo wathu imakhala ndi axon yomwe imakhala ngati foni yomwe imachititsa kuti mitsempha yazing'ono ikhale yovuta kwambiri kwa zinyama zapafupi. Neurons amatenga zofuna zambirimbiri kupyolera mu dendrites - zofiira zochepa zomwe zimachoka mosiyana. Mphepete mwa ubongo kusinthanitsa mauthenga ndi zikwi za nthambi zomwe zimakhala ndi axons ndi abambo, pamapeto a aliyense wa iwo pali synapse yomwe imadziwa zambiri. Neuron iliyonse ili ndi synapses zikwi zana.
Kuchotsa chidziwitso ichi ndi kubwezeretsa kumatchedwa kukumbukira. Izi zimachitika mothandizidwa ndi mapuloteni apadera, omwe ali mu chiberekero cha khungu - mbali yake yowonjezera ili ndi mutu wakuda. Kwa kanthawi, chidziwitsochi chimasungidwa ku hippocampus - malo apadera monga mawonekedwe a m'nyanja yam'mlengalenga yomwe ili m'kati mwa ubongo. Zimakhala ngati RAM ya kompyuta, komanso njira yosuntha zidziwitso ku chikumbukiro chosatha, pomwe hippocampus ikugwirizanitsa ndi ubongo wa ubongo, zikufanana ndi kulemba deta ku hard drive.
Mulimonsemo, maganizo athu amakhudzidwa ndi mafano, zithunzi zomwe zimadutsa m'maganizo mwathu, ndikukumana ndi chikumbumtima. Ndondomeko yaing'ono chabe ya chidziwitso kuchokera kukumbukira kwa nthawi yayitali, tikukumbukira. Njira yabwino yosunga chidziwitso kwa nthawi yayitali ndi kubwereza, ndikuyisunthira kumalo a kukumbukira nthawi yaitali. Ngati chidziwitsochi chimasinthidwa nthawi yayitali, chidzakhala chosasinthasintha ndipo chingagwiritsidwe ntchito kwa zaka zambiri.
Ndili ndi zaka, kukumbukira kukukulirakulira. Pokhala ndi zovuta za kukumbukira zaka, zimakhala zovuta kwa munthu kukumbukira zochitika zatsopano kusiyana ndi zochitika zakale zakutali. Kulephera kukumbukira kumakhala koonekera patapita zaka makumi asanu. Ngati nthawi isayambe kukhala ndi thanzi la ubongo, ndiye kuti kuwonongeka kwa msinkhu kumatha kukhala kukula kwa maganizo. Kusintha kwa ubongo wathu ndi kuchepa kwa kukumbukira kumachitika pang'onopang'ono ndipo kumayamba mofulumira. Anthu omwe ali ndi nzeru zochepa amatha kudwala matenda a Alzheimer's. Ngakhale kafukufuku waposachedwapa akutsimikizira kuti ichi si chifukwa chokha. Zindikirani kuti kupweteka maganizo ndi kupsinjika maganizo kumakhudza kwambiri ubongo ukalamba. Zosafunikira kwenikweni ndi chibadwa cha chibadwa. Pa ukalamba wa ubongo, zokolola zimakula, ubongo umagwira pang'onopang'ono ndi atrophies.
Ubongo wa munthu umakhala wolemera makilogalamu 1.3. Ubongo wa mayiyo ndi woposa 1.2 makilogalamu. Zimakhulupirira kuti ngakhale ubongo wa mkazi ndi zochepa, zimagwira ntchito bwino kwambiri. Chotsatira chake, luso la alangizi a osiyana amuna ndi akazi ndilofanana. Ubongo wazimayi ndi 55% wakuda, ndi wamwamuna - 50% okha. Izi zikulongosola luso lapamwamba la chilankhulidwe ndi kulankhula mwa amayi, komanso kutha kuyendayenda mu danga ndikudziwunikira zowona - mwa amuna.
Masiku ano, madokotala ali ndi chidziwitso ndi teknoloji yomwe imawathandiza kuti azindikire kusintha kwa ubongo kumayambiriro. Koma aliyense wa ife ayenera nthawi yomweyo kulingalira za mavuto athu ndi kukumbukira kuyambira ali wamng'ono, osati kuti asamangokhalira kuiwala. Imodzi mwa njira zabwino zogwiritsira ntchito ubongo wa ubongo ndi kupititsa patsogolo ntchito yokumbukila ndi ya wotchuka wotchuka wa zamagulu a California, Gary Small. Kwa iwo amene akufuna kukhala oganiza bwino ndi kukumbukira bwino, Dr. Small amapereka njira yake, yomwe ili ndi mfundo zitatu.
- Choyamba ndizowonetseratu, zomwe munthu ayenera kuzindikira mwatsatanetsatane.
- Yachiwiri ikujambula zithunzi, zomwe muyenera kupanga zithunzi zooneka bwino.
- Lachitatu ndi kugwirizana, ndiko kuti, kumangirira mafano a maganizo m'modzi.
