Omwe ali ndi vuto la kutchova juga amakonda kulandila mphotho zazikulu ngakhale atayika kwakanthawi pa Iowa Gossip Task (IGT), ndipo zovuta izi zimayenderana ndi dopamine dysfunctions.
Dopamine ndi neurotransmitter yolumikizidwa ndi kusakhalitsa kwakanthawi ndi kapangidwe ka zinthu zosokoneza bongo, zomwe zathandizira lingaliro lakusankha bwino komanso dopamine kukanika mu vuto la njuga.
Komabe, umboni wochokera pamavuto ogwiritsa ntchito mankhwala osokoneza bongo sungasamutsidwe mwachindunji ku vuto la kutchova juga.
TNkhani yake ikuyang'ana pamalingaliro atatu a zovuta za dopamine mu vuto la kutchova juga, zomwe zimawoneka ngati "zolakwika", mwachitsanzo, sizinathandizidwe mu maphunziro angapo a positron emission tomography (PET).
- "Kugwa" koyambirira kukusonyeza kuti vuto la kutchova juga lili ndi vuto lofanana ndi kugwiritsa ntchito mankhwala osokoneza bongo, limakhala ndi dopamine receptor. Palibe umboni womwe ukugwirizana ndi izi.
- “Chabodza” chachiwiri chikusonyeza kuti kusankha koipa pakubwera kwa juga kumayenderana ndi kutulutsidwa kwapaderaka nthawi yayitali. Palibe umboni womwe umathandizira chidwi, ndipo zolemba zokhudzana ndi kugwiritsa ntchito mankhwala osokoneza bongo zimapereka chithandizo chochepa pa lingaliro ili.
- "Chabodza" chachitatu chikuwonetsa kuti kusankha koyipa pakubwera kwa juga kumayenderana ndi kutulutsidwa kwa dopamine panthawi yopambana. Umboni sunathandizire izi.
M'malo mwake, kulembera dopaminergic kwa kulosera kwa mphotho ndi kusatsimikizika kungakhale bwino chifukwa cha kusokoneza kwa dopamine muvuto la kutchova njuga. Kafukufuku wolosera za mphotho ndi kusatsimikizika kwa mphotho kumawonetsa kuyankha kosadukiza kwa dopamine poyang'ana kukhudzika kwakukulu, komwe kungafotokoze kumasulidwa kwa dopamine ndi kutchova njuga ngakhale kutayika mu vuto la kutchova njuga. Zomwe zapezedwa kuchokera ku maphunziro omwe aperekedwa pano ndizogwirizana ndi lingaliro la kusokonekera kwa dopaminergic pakulosera kwa mphotho ndikulipira chizindikiro chosatsimikizika muvuto la kutchova juga.
