ZVINOTAURWA: kutarisira kwemubairo uye ruzivo runotenderera pamakwikwi akasiyana mukati memubhadharo mukuru wedunhu. Kusanganiswa kwekushanda kunowedzera humwe hunonakidza, uye hunowedzera ruzivo muuropi. Inzenza yepaIndaneti = kutarisirwa kwemaitiro.

Mubairo uye ruzivo ndiwo magwaro ekudzidza anobudirira anonyatsovimba nedopaminergic midbrain mhinduro.
Zvakawanikwa zvitsva zvinoratidza kuti kunyange mubairo uye ruzivo zvingangodaro zvakabatana, zvose zvinoshanda zvinogona kubhadharwa nemasumbu akasiyana neuronal.
Takashandisa zvakagadziriswa kushanda magnetic resonance imaging (fMRI) kuti iparadzanise mhinduro dzeveururu dzekupa mubairo uye ruzivo mukati mevanhu makurua nigra / ventral tegmental area (SN / VTA) yakaoma kuti iongorore kuderedza nzvimbo uye kubatana kwebasa- masango.
Tinoratidzira kuti masango akaparadzana mukati mechikamu chechipiri cheSN / VTA yemukati uye chikamu chinotevera chekodzero yeSN inonyanya kugadziriswa nekutarisira kwemubairo, wkuunganidza imwe nhengo dzeSN / VTA yepamutemo yakanyatsorongedzwa nemutsva.
Pamusoro pezvo, musangano weSN / VTA wekuchengetedza wakabatana unobatana nekubatana pakati pechizvarwa nemubairo apo ruzivo rwakasarudza kuwedzera mubairo-kutarisira mhinduro. Uku kuwirirana, zvakare, kwakaenzana nekusiyana kwemaitiro ekubatanidza-maitiro ematunhu aya eSN / VTA.
zvakananga, inoverengeka kana ichienzaniswa nemidziyo yakawanda-inofanirwa kubhadharwa inowedzera kuwedzera kwehutano hweS medial SN / VTA neye mesolimbic nzvimbo, kusanganisira nucleus accumbens uye hippocampus, pamwe chete neyokutanga inoona cortex.
Izvi zvinogona kuratidzira kushandiswa kwehutano hweS medial SN / VTA kunopa ruzivo rwekubatanidza pamusoro pechizvarwa uye mubairo, kana, zvakare, kuti basa reSN / VTA remukati rinogona kuenzanisa sei zvirongwa zvezviitiko zvenhau zvine chokuita nemipiro.
