Ts'ebetso ea mofuta o le mong oa neuron kahara cortex ea pele e ka tsosa toeba ho ja ho feta - ts'ibollo e ka bonts'ang mochine o bobebe oo boko ba motho bo bo sebelisang ho laola lijo.
Qeto ea ho ja ke ea bohlokoa bophelong ba phoofolo mme e laoloa ka karolo ke mekhoa ea khale ea metabolism e arolelanoang ke mefuta e mengata ea liphoofolo. Bo-rasaense ba belaelletse hore cortex ea pele, eo bathong ba amehang ho etsa liqeto tse hlophisehileng, e kanna ea ba le karolo ho laoleng boits'oaro ba ho ja, empa ba sa tsebe hantle hore na joang.
Khatisong ea Jan. 19 ea koranta ea Natural Neuroscience, Bafuputsi ba Yale ba tlaleha ho eketseha ha lijo tsa litoeba ka ho kenya tšebetsong li-D1 dopamine-receptor neurons ka pele ho cortex ea litoeba. Ho thibela li-neuron ho ile ha lebisa litoeba ho fepa hanyane.
Se fumanoeng se boetse se fana ka maikutlo a ho kopanya tsela ea dopamine e amanang le libaka tse ling tsa boko tse kang amygdala, eo nalaneng e neng e hokahane le karabelo ea maikutlo le tšabo. Se fumanoeng se fana ka maikutlo a hore boikoetliso ba ho ja bo ka ba karolo pakeng tsa karohano e lipakeng tsa libaka tse etsang liqeto tsa bokong le libaka tsa pele.
"Bafuputsi ba tloaetse ho ba kampong e lumelang hore taolo ea ho ja e laoloa kaofela ho tloha holimo ho ea holimo, kapa ho tloha tlase," ho boletse Ralph DiLeone, moprofesa ea amanang le mafu a kelello le neurobiology ebile e le sengoli se phahameng sa pampiri. "Ka bobeli li bohlokoa mme pampiri ena e tlisa tlhaloso e eketsehileng ea methapo ea kutlo potsong."
