Sleeping kwicala okulungileyo ukuba ubuchopho

Asinto iindaba ukuba imeko apho umntu ulele, zingachaphazela ukuma kunye ukwetyisa, kodwa ujika ube negalelo elikhulu sengqondo kunye nempilo yengqondo. Izifundo zakutshanje aye abonisa uxhulumaniso yalo ubuchule ingqondo ukuba baphumeze ukutya olufanelekileyo, kubandakanywa ukususwa amalaphu iikhemikhali eziyingozi. Ngoko ke, kukho ukuma olele ngakumbi ikhethwayo kangako.

Kutheni kungcono ukuba ndilale kwicala lakhe?

Izazinzulu ziye zafumanisa ukuba elele ngecala lakho kunokuba ngomqolo okanye isisu sakho. Esi sikhundla spatial kuvumela umzimba ukuba ngempumelelo ngakumbi balahle inkunkuma yemichiza ebuchotsheni. Bemi University of Rochester (New York) Maiken Nedergard, ochithe iqela leekheyisitadi, ithi ulwazi olunomdla: kweso sikhundla kudla nozintyintya ebhedini ezininzi izilwanyana, kuquka nabemi zasendle, yaye abantu bakhetha ukuphumla enkulu yalo pose ethile . Le Isazinzulu ukholelwa ukuba kule meko ingqondo kakhulu ngempumelelo wahlambuluka inkunkuma pathways okongezeleke uphaphama.

Ekuhloleni zabo, abaphengululi basebenzisa indlela yidityaniso olutshintshatshintshayo umahluko livakale magnetic umfanekiso (MRI), nto leyo ukuba imbono olungcono utshintsho kwemichiza kulo izakhiwo zangaphakathi izicwili ezahlukeneyo ingqondo, ingakumbi, ebizwa njalo-glimfatichesky umendo (inkqubo apho utywala filter, oko kukuthi, ulwelo lwe-cerebrospinal kwaye kwaneso kunye ulwelo Embi ezingqonge ezinye zonke iiseli zomzimba). Lo msebenzi kubalulekile ukusebenza komzimba ikuvumela ukuba balahle inkunkuma kunye namanye amachiza ukuba yande ingqondo kwaye isuswe (umz, beta-amyloid neprotheyini tau). nako ngokugqithiseleyo yabo kunokubangela Alzheimer kunye Parkinson wakhe.

Njengoko amalinge kunye yolingo lwezonyango, inkqubo yokususwa beta-amyloid luvuliwe ngexesha ubuthongo. Kodwa loo nto bonke. Ukuyicoca ngamandla ichaphazela pose apho umntu okanye isilwanyana ilele.

Kakuhle eli wokulinga

Yemifuniselo zenziwa abadala yeempuku laboratory elintyumpantyumpeka ubuthongo eyenziweyo (anesthetized) kunye mboleko zipakishwe omnye kwizikhundla ezithathu (ecaleni, ngomhla esiswini okanye umva). Emva koko, isifundo ubuze glimfatichesky indlela ingqondo izilwanyana belele.

Njengoko kuchaziwe nguGqirha Helene Benveniste, intsebenziswano umbhali zesifundo, ogama iziphumo yapapashwa magazini "Neyrosayns", uhlalutyo wabonisa ukuba ukutya waphumelela xa ubuthongo iqatshelwe sikhundla lateral. Njengokuba wathi, ezi zinto zifunyanisiweyo isicelo ngombandela nabantu. Buza ngokulala kwicala ngokucacileyo kuluncedo ngaphezu imigaqo ngasemva okanye isisu.

Noba oku kuyinyaniso ngokuphathelele ebantwini?

Umzekelo "Abazalwana ezincinane" libonisa ukuba ezanyisayo (izinja, iikati, kwaye nkqu iindlovu) bakhetha ukulala ngaloo ndlela, nangona ababhali ayikwazanga mazingasileli ukuqaphela ukuba ukuziphatha wendlela isilwanyana sasendle nayo kwasekwa phantsi kwempembelelo kweemeko ukusinda yaye, ke ngoko, ukuze azifani kwabantu. Olu phando lwenziwa kwi iimpuku hayi unika kodwa ngokupheleleyo izizathu ukutshintshela iziphumo ebantwini, nangona akukho umbono omhle.

iintlobo ezininzi dementia anxulunyaniswa ukuphazamiseka kokulala, kuquka ubunzima yokulala. Kubonakele ubungqina obukhulayo ukuba ezi ukuphazamiseka ukuze ukukhawulezisa memory ilahleko isifo i-Alzheimer. "Iziphumo zethu zinika umbono omtsha ngalo mba, ebonisa ukubaluleka kokuma xa ulele," - wathi esiphelweni Nedergard.
