Sei vanhu vose vasingadi kuteerera mutinhi?

Mimhanzi ine simba rekutiita kuti tinzwe takanaka uye tifare, asi kune vamwe vanhu hazvina maturo akadaro. Kwete, izvi zvisingagoni kupomerwa nekushaiwa kwemweya, asi vanyori vekudzidza kutsva vanoti panzvimbo pezvo vanhu ava vanoona izvo zvinonzi mimhanzi anhedonia. Izvi zvinoreva kuti uropi hwavo hahukwanise kupindura mimhanzi.

Kusiyanana kwakavanzwa mupfungwa dzedu

Kunyora uropi hwezvidzidzo gumi nemitambo ye anhedonia uye kuenzanisa nhamba yavo nedhizinesi dzevanhu vasingatambudziki nechishamiso ichi, vatsvakurudzi vakakwanisa kuziva kuti basa re neuronal mumapoka maviri aya rakasiyana sei. Nokudaro, masayendisiti akakwanisa kutsanangura kuti sei vamwe vanhu vasingadi kuteerera mimhanzi.

Kushandisa magnetic resonance imaging (fMRI), vatsvakurudzi vakawana kuti kana vanhu vane anhedonia yemimhanzi vari kuteerera mimhanzi, vane zvikamu zvakaderera zvebasa munharaunda yeuropi iyo inonzi nucleus yenucleus kune vanhu vasina izvi.

Chikonzero nei mubhadharo wekubhadhara usashanda

Tichifunga kuti chinonyanya kukosha chikamu chepurogiramu yehuropi, izvi zvingaita sokutsanangura kuti sei vanhu ava vasingagoni kuve vakafuridzirwa nekunzwika kwemimhanzi. Kunyange zvakadaro, pavakatora chikamu mubasa rekusetsa, mhinduro yechekisi yakatarisana yakanga yakasimba seyomunhu asina anhedonia yemimhanzi. Izvi zvinoratidza kuti chirongwa chavo chemaropafadzo chinoshanda zvakakwana, uye nyaya iyi inonyatsoenderana nemimhanzi.

Zvadaro vatsvakurudzi vakafunga nezvehutano hwekubatanidza pakati pekugadzirisa mupiro, iyo inonzi "ventral striatum" (inosanganisira nucleus inogadzikana) uye cortex yekuongorora yeuropi, apo manzwiro anotorwa. Varwere vane anhedonia yemimhanzi vane yepamusoro yehutano kune vanhu vane tsika dzakanaka kumimhanzi.

Rimwe boka revanhu gumi nemashanu vaine ruzivo rwakanyanya rwemimhanzi rwakaratidza kushamwaridzana kukuru pakati pe ventral striatum uye cortex yokuongorora.

Mhedziso yevasayendisiti

Mukudhinda zvitsva muPuritatimende ye National Academy of Sciences, vatsvakurudzi vanonyora kuti: "Rwiyo rwe anedonia runogona kuwirirana nekuderera kwekubatana pakati pekuongorora cortex uye subcortical network ye mubhadharo. Izvi zvinoratidza basa rinokosha rekubatana kwakadaro mukufungidzira kwemimhanzi. " Zvisinei, chii chinokonzera kusiyana uku, masayendisiti asati avepo.
