Ho lumeloa hore mokhoa oa dopamine o ama boitšoaro ba papali ea chelete papaling ea papali ea chelete. Haholo-holo, ho lokolloa ha dopamine ka har'a ventral striatum ho bonahala ho ama ho etsa liqeto bothateng bona. Phuputso ena e fuputse ho lokolloa ha dopamine kahare ho terri striatum mabapi le ts'ebetso ea papali ea chelete ho Iowa Gossip Task (IGT) ho 16 Pathological Gamblers (PG) le 14 Healthy Controls (HC). Re sebelisitse Positron Emission Tomography (PET) ho lekanya bokhoni bo kopanyang ba [(11) C] raclopride ho dopamine D2 / 3 receptors nakong ea boemo ba motheo le papali ea chelete. Re ile ra nahana ka hore ho fokotse matla a kopanyang a raclopride maemong a potral striatum nakong ea papali ea chelete (ho bonts'a ho lokolloa ha dopamine) ho ka amahanngoa le ts'ebetso e phahameng ea IGT ho Litaelo tsa Bophelo, empa ts'ebetso ea IGT e tlase ho Pathological Gamblers. Liphetho li bonts'itse hore Pathological Gamblers e nang le dopamine e lokolloang ka har'a "ventral striatum" e ne e fokolitse ts'ebetso ea IGT haholo ho feta Controls ea Healthy. Ho feta moo, ho lokolloa ha dopamine ho ne ho amahanngoa le ts'ebetso e phahameng haholo ea IGT ho li-Controls tse phetseng hantle le ts'ebetso e tlase haholo ea IGT ho li-Pathological Gambler. Liphetho li fana ka maikutlo a hore ho lokolloa ha dopamine ho ameha ka bobeli ha ho etsoa liqeto tse hlakileng le tse fosahetseng. Liphumano tsena li ka tlatsetsa kutloisisong e ntle ea dysamine ea dopaminergic papaling ea papali ea chelete le lithethefatsi tse amanang le lithethefatsi.
