Iyo peri-aqueductal grey iri mu brain brain, chikamu chakachengetedzwa panguva yekushanduka kweiyo inonzi "reptilian brain" iri kure pasi pegrey nyaya ye cerebral cortex, inonzi colloquially inonzi "thinking hood". Mufananidzo uyu unoratidza pfungwa yese.

Zvemweya uye zvekunamata zvinogona kunge zvine hukama nemasekete e-neural munharaunda yeperiaqueductal grey (PAG) yehuropi stem, maererano nechidzidzo chitsva (Ferguson et al., 2021).
"Zvatinowana zvinoratidza kuti zvekunamata uye zvekunamata zvakadzika midzi mune zvakakosha neurobiological dynamics uye zvakadzika midzi muuropi hwedu," akadaro munyori anotungamira Michael Ferguson mune yaChikunguru 1 kuburitswa kwenhau. "Takashamiswa kuona kuti iyi dunhu rehuropi rekunamata rinotarisa pane imwe yenzvimbo dzakachengetedzwa dzehuropi mukushanduka-shanduka."
Ferguson et al. vakashandisa nzira inonzi "injury network mapping" kuti vaone kana vangakwanisa kuona kana kuti kwete neural circuit yekunamata uye yekunamata mune 193 varwere vakakuvadzwa uropi. Iyi nzira yakashandiswa kumaseti maviri ekukuvara kwehuropi (N1 = 88; N2 = 105) "kuedza kana nzvimbo dzekukuvadzwa dzine chokuita nezvitendero zvemweya uye zvechitendero dzinoenderana nedunhu rehuropi hwevanhu."
"Takaona kuti kukuvadzwa kwehuropi kwakabatana nemweya wekuzvizivisa kunoenderana nedunhu rehuropi rakanangana neperiaqueductal grey," vanyori vanotsanangura mune yavo abstract. "Mharadzano yenzvimbo dzekukuvara nedunhu rimwechete rinoenderana nekuzvizivisa kwechinamato mune yakaparadzana data set, pamwe nemishumo yapfuura pamusoro pekukuvara kwakabatana nechitendero. «
Kubva pane izvi zvawanikwa, Ferguson et al. kupedzisa: "[Yedu] Migumisiro inoratidza kuti zvekunamata uye zvekunamata zvinowirirana nedunhu rehuropi rakafanana rinotarisa periaqueductal grey, nharaunda yebrainstem yaimbove yakabatanidzwa mukutya, kugadzirisa marwadzo uye maitiro ekuzvipira. «
Hyperreligiousness kana kushayikwa kwemweya kunopihwa akasiyana PAG node
Yekutanga data set yaisanganisira 88 neurosurgery varwere vakavhiyiwa uropi kuti vabvise maronda akaparadzirwa zvakanyanya muhuropi. Vakapindurawo mibvunzo pamusoro pe "kugamuchirwa kwemweya" vasati vavhiyiwa uye mushure mekuvhiyiwa.
Yechipiri data set yaisanganisira 105 veterans vane kukuvara kwehuropi kubva muHondo yeVietnam. Ava varwere vakapindura kuongororo nemibvunzo pamusoro pechitendero chavo (semuenzaniso, "Unozviona uri munhu wechitendero here? Hongu kana kwete?").
Ichishandisa mepu yekukuvara kwetiweki, timu yeBWH yakaona kuti kuzvitaura zvekunamata kana chitendero chakanangana nemasekete ehuropi akatarisana nePAG. Sezvineiwo, iyi PAG yedunhu inosanganisira "yakanaka" uye "negative" node. Zvinenge senge "on / off" switch, kukuvara kwehuropi kwakavhiringidza dzimwe nodes kwakaratidzika kuwedzera kana kuderedza kuzvitaura kwezvitendero nezvemweya.
Ongororo yezvinyorwa zviripo nevatsvakurudzi zvakafumurawo "mishumo yakawanda yevarwere vakava hyperreligious mushure mekutambudzika kwehuropi hunokanganisa node dzisina kunaka muuropi." [P] dunhu. Kusiyana neizvi, mauto akavhiringidza dzimwe node munharaunda yePAG yebrainstem yakaratidzika kuderedza mweya uye chitendero.
Pane yakasarudzika uye yakasarudzika "nzvimbo yehumwari" muhuropi hwemunhu? Zvimwe kwete.
Chidzidzo chekare (Johnstone et al., 2012) muvarwere vakakuvadzwa muuropi nevatsvakurudzi veYunivhesiti yeMissouri-Columbia vakakwanisa kudzokorora zvidzidzo zvekare kubva panguva ino zvakaratidza "kuti dunhu reparietal rinobatanidzwa mune zvemweya uye zvechitendero. ." . Vanyori vakafungidzirawo kuti 'kudzikisira kutarisisa kune wega (kureva, kuzvida), pamwe nekudzikira kwekurudyi parietal lobe (RPL) basa, inoshanda sehwaro huru hwekukosha neuropsychological kune yemweya.
Anenge makore gumi apfuura, Johnstone et al. akanyora kuti: "Kuwedzera kwemberi kwerobe basa kunoratidzika kunge kwakabatana nemaitiro echitendero anowanzoitika (uye zviitiko zvemweya zvishoma)." Zvisinei, vakacherechedzawo kuti "iyo chaiyo neuropsychological process / mechanism [yekupfuura kwemweya] inoramba isina chokwadi."
"Takawana hwaro hwepfungwa dzezvemweya, asi haisi yega kune imwe nzvimbo yeuropi," akadaro munyori wekutanga Brick Johnstone mupepanhau reKubvumbi 2012. "Kunamata ipfungwa ine simba zvakanyanya inoshandiswa nevakawanda. zvikamu zveuropi. Dzimwe nzvimbo dzehuropi dzinotamba mabasa makuru, asi ose anoshanda pamwechete kufambisa zviitiko zvevanhu zvepamweya.
Mune yaNyamavhuvhu 2012 PsychologyBlog blog post, Nigel Barber akataura nezvechidzidzo ichi. Akagumisa kuti "zviitiko zvemweya zvinoshandisa zvikamu zvakasiyana-siyana zveuropi: pfungwa yehumwari inoshanda panzvimbo yeanatomical."
Iyo "nzvimbo yehumwari" inogona kunge iine midzi inoshanda yakabatana nehuropi hwedu hwezvino reptilian
Kuunganidza humbowo hunoratidza kuti kubatana kunoshanda pakati penzvimbo dzecortical dzehuropi uye subcortical nzvimbo dziri pazasi pecerebral cortex inoita basa raimbove risingatarisirwe mukuziva kwehuropi hwese. (Ona, "Kushuvira kwangu kwemakumi emakore-kurebesa decode yekutanga 'Super 8′ mepu yeuropi").
Zvichienderana nekuenderera kwangu kufarira muuropi uye kusiri kwehuropi kushanda kwekubatana, chinhu chinonakidza chechangobva kuitika (2021) tsvagiridzo yezvemweya uye chinamato paHarvard Medical School ndiyo mukana wekuti hyper-religious zvitendero kana kushomeka kwemweya kungave kwakabatana neuronal. zvirwere. masekete akadzika mu subcortical "asiri-kufunga" zvikamu zvehuropi hwedu hwereptilian. Ehe, kutsvagisa kwakawanda kunodiwa kuti unzwisise zviri nani kuti ese aya neural network akabatana sei.
Mukuburitswa kwenhau yeBWH ichangoburwa, Ferguson anoyambira nezve 'kududzira zvakanyanya' zvakawanikwa nechikwata chake, achicherekedza kuti data seti mbiri dzakashandiswa pakuongorora kwake hadzina kupa ruzivo rwakawanda pamusoro peudiki uye dzidzo yeudiki yevarwere vakasiyana, izvo zvakapesvedzera mune zvekunamata uye zvekunamata. kukura.
Uyezve, ese ese e data seti aingosanganisira varwere vanobva kuzhinji tsika dzechiKristu. Tichifambira mberi, mukuedza kunzwisisa zviri nani kuwanda kwezvavachangobva kuwana, vatsvakurudzi veBrigham vanobvuma kuti "vanofanira kudzokorora chidzidzo chavo muzvirongwa zvakawanda."
Nenguva isipi, Ferguson anofarirawo kuongorora kana zvaakawana munguva pfupi yapfuura zvine chekuita nePAG neural circuits zvine chekuita nezvekunamata uye zvekunamata zvingave nemakiriniki ekushandisa.
“Nguva pfupi yapfuura ndipo apo mishonga nemweya zvakaparadzana. Zvinoita senge paine chinongedzo chisingaperi pakati pekuporeswa nekunamata mutsika nemagariro ese, ”akagumisa Ferguson. "Ndiri kufarira kusvika pakunzwisisa kwedu matunhu ehuropi kunogona kubatsira kubvunza mibvunzo ine ruzivo rwesainzi uye yekiriniki inoturikira pamusoro pekuti kuporesa uye zvekunamata zvinogona kuzivisana sei."
