A itsva mhando phantom rokuyeuka?

Major zvinowanikwa nesayenzi mukwanisi anotungamirira dzidziso ndangariro, pashure vanotsvakurudza vakaona kuti uropi anogona "chinyararire" kuchengeta mashoko, kutanga ghostly ndangariro kuti vasina Neural zvisikwa.

Two Mhando ndangariro

Vakawanda vanobvuma kuti pane mhando mbiri ndangariro. Chokutanga izvi rinozivikanwa kushanda ndangariro. Zvinonzi kusashanda apo isu ironge mashoko matsva, chengeta mupfungwa dzako uye pfungwa, kwete kuti kukanganwa. Izvi dzinongoita raitungamirwa hippocampus, sezvamakaropafadzwa Tutsinga tunofambisa mashoko utwu ushande dzose. Isu tiine wevasungwa yedu nezvokuti kuedza kuyeuka.

Kunyange zvakadaro, nguva yakareba Ndangariro zvinochengeterwa mudura cortical kumatunhu uropi uye encrypted mune dzimwe nzira Neural, akadana engrams. Vanova unongoshanda kana isu kubvisa izvi yakananga ndangariro.

Chechitatu mhando ndangariro

Pakuongorora itsva nesayenzi yakabudiswa mumagazini inonzi Science, neuroscientists akashuma kuyeuka rechitatu mhando iri dzakaonekwa, yavanoti "Zvinokosha kuyeuka kwenguva refu." Musiyano mukuru pakati maonero ichi uye vaviri dzakaonekwa kwokutanga huru, ndechokuti Data nechokuita mutsva mhando, unogona chaizvoizvo kuchengetwa pose pfungwa uye zvinogona kunzi sezvinodiwa.

dzinonakidza ruzivo

The chikwata akashandisa dzichipfekeka rinobva resonance kuri kuongorora uropi vechikamu. The vanotongwa vaiona dzakatevedzana mashoko, vanhu uye marudzi. Nemhaka MRI algorithm, vatsvakurudzi vaikwanisa kuziva chaizvo mifananidzo muuropi cortex, chokuita nomumwe incentives izvi.

Zvino nyaya wawakaratidzwa yegwara zvinhu zviri panguva kunokonzera mhando mbiri dzakasiyana kwouropi basa. Apo vatori vechikamu vakakumbirwa kuti pfungwa chete imwe zvinhu izvi uye kusateerera mumwe, mumwe mapatani izvi vakanyangarika, izvo zvinoratidza kuti iye zvakabviswa kushanda ndangariro.

Masayendisiti anodavira kuti kushanda ndangariro inoda kuti akaramba kushanda Tutsinga tunofambisa mashoko utwu. Zvisinei, pasinei neizvi, bvunzo vachiri mudura kuyeuka kukanganwa nyaya iyi. Vanhu mhinduro dzemibvunzo pamusoro chii vaona, anoratidza kuti zvifananidzo zvinhu zvichiripo zvimwe chikamu pfungwa dzavo, apo pasina Tutsinga tunofambisa mashoko utwu vanoita sevasina kuratidza chokwadi ichi.

"Vanhu vanogara aifunga kuti Tutsinga tunofambisa mashoko utwu vanofanira kuramba kushanda kuitira kuti tigone kuramba chinhu mupfungwa, - akatsanangura yokudzidza co-munyori Bradley Postl. - Asi isu takaona kuti vanhu vanenge regai kurangarira chinhu, kwete kuratidza chero basa chokuita Tutsinga tunofambisa mashoko utwu ".

The mashandiro yechitatu mhando ndangariro haina aizvinzwisisa

Kudzidza Vanyori zvakare akawana kuti masero uropi pamwe rinobva pulses kuti vakasonganira idzi anyangarika, vakakwanisa ndimutsidzire basa mapatani kwakaitika panguva apo vechikamu pakutanga vaizoisa pfungwa dzavo panyaya iyi. Zvinoita kuti ufunge incentives izvi.

Kunyange zvazvo vaongorori havagoni kutsanangura chaizvo kwacho kunoitika muna Hemisférios Cerebrais, ivo vakafungidzira kuti phantom ndangariro kwakavakirwa "tichishingaira-quiescent" The mashandiro naro mashoko neimwe nzira ugoponeswa synapses pakati Tutsinga tunofambisa mashoko utwu, kunyange apo Tutsinga tunofambisa mashoko utwu izvi Haana basa .
