Iwe unoda kuve neyakanaka ndangariro? Rara zvakanaka! Mushure mezvose, chikamu cheREM kurara (REM-chikamu, apo zviroto zvinoonekwa uye nekukurumidza kufamba kweziso kunotanga) inobatanidzwa zvakananga mukuumbwa kwendangariro. Masayendisiti akataura izvi kanopfuura kamwe chete, asi nguva pfupi yadarika ndipo pakakwanisa kuratidza kuti chiitiko cheeuroni chinotungamira kuchinjisa ruzivo kubva pfupi-pfupi kuenda kune refu-ndangariro chakakosha zvakanyanya muchikamu chekurara cheREM. Masayendisiti kuYunivhesiti yeBern uye neDouglas Institute yeMental Health paMcGill University vakaita izvi zvakawanikwa, izvo zvinoratidzira kukosha kwekurara kwakanaka zvine hutano. Mhedzisiro yekutsvagurudza kwavo yakaburitswa mumagazini Sayenzi, iyo portal Neurotechnology.rf inonyora zvakadzama nezvayo.
Chero ruzivo rwuchangobva kuwanikwa rwunotanga kuchengetwa mumhando dzakasiyana dzeyeuchidzo, semuenzaniso, nzvimbo kana manzwiro, uye ipapo chete ndipo paunosunganidzwa kana kusimbiswa, uchibva kune pfupi-pfupi kuenda kune refu-temu. “Maitiro anoita huropi maitiro aya anoramba asina kujeka kusvika parizvino. Kekutanga, takakwanisa kuratidza kuti kurara kweREM kwakakosha zvakanyanya pakuumbwa kwenzvimbo yekurangarira mumakonzo, "anotsanangura mumwe wevanyori vechidzidzo ichi, Sylvain Williams.
Kuti uite izvi, vesaenzi vakaita ongororo pamakonzo: makonzo ari muchikwata chekutonga aibvumidzwa kurara senguva dzose, uye mbeva muboka rekuyedza panguva yeREM yekurara chikamu "chakadzima" mauroni anoitisa ndangariro, achiaita iwo nemwenje. Mushure mekuratidzwa kwakadai, mbeva idzi hadzina kuziva izvo zvinhu zvavakange vambodzidza, sekunge ndangariro yavo yakanga yadzimwa.
Uye hechino chakakosha zvakanyanya, icho chinoonekwa nemunyori anotungamira wedzidzo, Richard Boyes: “Kudzima maeuron iwaya, asi kunze kwezvikamu zvekurara zveREM, hakuna zvazvakabatsira mundangariro. Izvi zvinoreva kuti chiitiko cheeuronal panguva yekurara kweREM chakakosha kune yakasarudzika ndangariro yekusimbisa. ”
Kurara kweREM kunoonekwa sechinhu chakakosha pakurara kutenderera mune zvese zvipenyu, kusanganisira vanhu. Masayendisiti anowedzera kubatanidza hunhu hwayo husina kunaka nechitarisiko chehuropi hwakasiyana senge Alzheimer's kana Parkinson. Kunyanya, kurara kweREM kunowanzo shatiswa zvakanyanya muchirwere cheAlzheimer, uye mhedzisiro yechidzidzo ichi inoratidza kuti kukanganisa kwakadaro kunogona kukanganisa zvakananga kukanganisika kwekurangarira mu "Alzheimer's" pathology, vanotsvaga vanoti.
Kuti muviri ushandise iyo nguva yaunoda muchikamu cheREM, edza kurara uchienderera kwenguva inokwana maawa masere: kana kurara kuchikanganiswa kazhinji, huropi hunoshandisa nguva shoma muchikamu chino.
Iwe unogona kuverenga zvishoma zvishoma nezve ichi chinonakidza kuyedza kwemasayendisiti pazasi.

Mazana ezvidzidzo zvakapfuura akaedza zvisina kubudirira kupatsanura neural chiitiko panguva yekurara uchishandisa echinyakare nzira dzekuyedza. Panguva ino, vesaenzi vakatora imwe nzira. Ivo vakashandisa ichangobva kugadzirwa uye yatove yakakurumbira optogenetic imaging nzira pakati peeurophysiologists, iyo yakavabvumidza kunyatso tsanangudza tarisiro yehuwandu hwehuwandu hweeuron uye kudzora zviitiko zvavo pasi pesimba rechiedza.
"Isu takasarudza iwo mauroni anodzora mashandiro emukoko, chimiro chinoumba ndangariro panguva yekumuka, uye nehurongwa hweGPS yehuropi," anodaro Williams.
Kuti vaedze ndangariro yenguva refu yepakati mumakonzo, vesaenzi vakadzidzisa makonzo kuona chinhu chitsva munzvimbo inodzorwa, uko kwaitove nechimwe chinhu chavakamboongorora uye chakafanana neicho chitsva muchimiro uye huwandu. Mbeva dzakapedza nguva yakawanda dzichiongorora "zvitsva", uye nekudaro dzakaratidza maitiro avo kudzidza uye kurangarira izvo zvakambodzidziswa zvaiitika.
Kana mbeva idzi dzaive muhope dzeREM, vaongorori vakashandisa pulses yechiedza kudzima ma-neurone ane chekuita nendangariro uye kuona kuti izvi zvingakanganisa sei kubatanidzwa kwendangariro. Zuva rakatevera, aya makonzo akakundikana zvachose basa rekushandisa spatial memory, isingaratidze kana chidimbu chidiki chechiitiko chavaive vagamuchira nezuro wacho. Kuenzaniswa neboka rinodzora, ndangariro yavo yaiita kunge yakadzimwa.
