Chii chichaitika kumunhu kana angosara nehafu yeuropi hwake? Tinofunga kuti mhinduro iri pachena. Iyo nhengo inobata maitiro akakosha ehupenyu yakaoma, uye kurasikirwa kwechikamu chakakosha chayo kunogona kutungamirira kumigumisiro inotyisa uye isingagadzirisiki. Nekudaro, kugona kwehuropi hwedu kuchiri kushamisa kunyangwe nyanzvi dzezveuropi. Biopsychologist Sebastian Ocklenburg anogovera zvakawanikwa patsvagiridzo zvinonzwika sechirongwa chebhaisikopo resci-fi.
Dzimwe nguva, vanachiremba vanofanirwa kuenda kumatanho akanyanya kuponesa hupenyu hwevanhu. Imwe yenzira dzakanyanyisa mukuita neurosurgery ndeye hemispherectomy, kubviswa kwakakwana kweimwe yehemispheres yecerebral. Maitiro aya anoitwa chete muzviitiko zvisingawanzoitiki zvepfari isingagoneki senzira yekupedzisira kana dzimwe sarudzo dzese dzatadza. Kana iyo yakakanganiswa hemisphere inobviswa, kuwanda kwepfari pfari, imwe neimwe iyo inoisa hupenyu hwemurwere, inoderedzwa zvakanyanya kana kunyangarika zvachose. Asi chii chinoitika kumurwere?
Biopsychologist Sebastian Ocklenburg anoziva zvakawanda pamusoro pekuti uropi nemaneurotransmitters zvinokanganisa sei maitiro evanhu, pfungwa, uye manzwiro avo. Anotaura nezvechidzidzo chechangobva kuitika chinobatsira kunzwisisa kuti uropi hunogona kushanda sei kana hafu chete yasara yasara.
Masayendisiti akaongorora hutano hwehuropi muvarwere vakati wandei, mumwe nemumwe wavo aive nehemisphere imwe yakabviswa muhudiki. Migumisiro yekuedza inoratidza kukwanisa kwehuropi kuronga patsva kunyange mushure mekukuvadza kwakanyanya, kana kukanganisa uku kukaitika pazera duku.
Kunyangwe pasina chero mabasa chaiwo, uropi hunoshanda zvakanyanya: semuenzaniso, mune ino mamiriro tinorota
Vanyori vakashandisa neurobiological nzira yekushanda magnetic resonance imaging (MRI) pakuzorora. Muchidzidzo ichi, pfungwa dzevatori vechikamu dzinoongororwa pachishandiswa MRI scanner, muchina une zvipatara zvakawanda mazuva ano. Iyo MRI scanner inoshandiswa kugadzira akatevedzana emifananidzo yenhengo dzemuviri zvichienderana neadzo magineti.
Inoshanda MRI inoshandiswa kugadzira mifananidzo yehuropi panguva yebasa chairo. Somuenzaniso, munhu wacho anotaura kana kufambisa zvigunwe zvake. Kugadzira mutsara wemifananidzo pakuzorora, muongorori anobvunza murwere kuti arare achiri mu scanner uye asaite chinhu.
Kunyange zvakadaro, kunyange pasina chero mabasa chaiwo, uropi hunoratidza basa rakawanda: somuenzaniso, mumamiriro ezvinhu aya tinorota, uye pfungwa dzedu "dzinodzungaira". Nekuona kuti ndedzipi nzvimbo dzehuropi dzinoshanda kana dzakarara, vaongorori vakakwanisa kuwana maitiro ayo anoshanda.
Masayendisiti akaongorora mambure ekuzorora muboka revarwere vakavhiyiwa kuti vabvise hafu yehuropi hwavo muhuduku hwepakutanga uye vakaenzanisa neboka rinodzora revatori vechikamu vaive nehafu yehuropi inoshanda.
Uropi hwedu hunoshamisa
Migumisiro yacho yaishamisa zvechokwadi. Mumwe angatarisira kuti kubviswa kwehafu yeuropi kunovhiringidza zvakanyanya sangano rayo. Nekudaro, network yevarwere vari kuvhiyiwa yakadai yaitaridzika zvinoshamisa yakafanana neiyo yeboka rekutonga revanhu vane hutano.
Vatsvaguri vakacherekedza nomwe dzakasiyana siyana dzinoshanda network, senge idzo dzakabatanidzwa nekutarisa, kuona uye mota kugona. Mune varwere vane hafu-uropi yakabviswa, kuwirirana pakati penharaunda dzehuropi mukati mehutano hwakafanana hwekushanda hwakanga hwakafanana neiyo yeboka rekutonga rine zvose hemispheres. Izvi zvinoreva kuti varwere vakaratidza kukura kwehuropi, kunyangwe kusavapo kwehafu yacho.
Kana kuvhiyiwa kwacho kuchiitwa achiri mudiki, murwere anowanzo chengetedza maitiro ekuziva uye njere.
Nekudaro, pakanga paine mutsauko mumwechete: varwere vaive nekuwedzera kwakajeka kwekubatana pakati pemambure akasiyana. Izvi zvakasimbiswa zvinongedzo zvinoita sezvinoratidza maitiro ekugadzirisa cortical mushure mekubviswa kwehafu yehuropi. Nekubatana kwakasimba pakati pehuropi hwose, vanhu ava vanoratidzika kuva vanokwanisa kurarama nekurasikirwa kweimwe nyika. Kana kuvhiyiwa kuchiitwa achiri mudiki, murwere anowanzo chengetedza maitiro ekuziva uye njere, uye anogona kurarama hupenyu hwakajairika.
Izvi zvinotonyanya kushamisa kana iwe uchifunga kuti kukuvadzwa kwehuropi gare gare muhupenyu-somuenzaniso, nesitiroko-kunogona kuva nemhedzisiro yakakomba yekugona kunzwisisa, kunyangwe nzvimbo diki dzehuropi dzakakuvadzwa.
Zviri pachena kuti muripo wakadaro hauitike nguva dzose uye kwete pazera ripi zvaro. Nekudaro, mhedzisiro yeongororo inoita mupiro wakakura pakudzidza kwehuropi. Pachine mikaha yakawanda munzvimbo ino yeruzivo, zvinoreva kuti neurophysiologists uye biopsychologists vane nzvimbo yakafara yebasa, uye vanyori nevanyori vezviratidziro vane nzvimbo yekufungidzira.
