Belgian cov kws tshawb fawb tau ua ib txoj kev tshawb fawb, thaum lub ntsiab lus ntawm cov txheej txheem ntawm kev cim cov ntaub ntawv ntawm qib tsis nco qab tau kawm. Nws muab tawm tias nyob rau hauv cov kev mob ntawd, cov kev them nyiaj sab hauv yuav pab kom cim cov ntaub ntawv.
Nws sim, cov kws tshawb fawb, sawv cev rau Löwensky Catholic University (Belgium), ua nrog kev koom tes ntawm primates - cov tsiaj uas nws cov neeg txheeb ze yog poj niam niaj hnub. Nyob rau hauv cov txheej txheem tshawb fawb, cov liab thauj khoom nyob rau hauv txhua txoj haujlwm nyuaj, thaum, thaum lub sijhawm kuaj, lawv tau pom cov duab ntawm daim duab uas yog qhov muag plooj lossis ib tus neeg lub ntsej muag. Nws yog tsim nyog sau tseg tias txoj haujlwm tau xaiv kom tau tias nws tsis tau sib txuas lus nrog kev paub ntawm cov tib neeg thiab cov nuj nqis, uas tau ua tiav qee qhov "cuam tshuam" ntawm cov tsiaj. Thaum lub sijhawm ua haujlwm tau nqa tawm, cov kws tshawb nrhiav tau ua rau thaj chaw ventral ntawm lub log ntawm primates. Qhov chaw kuaj mob hlwb no yog cov khoom siv tseem ceeb ntawm dopamine thiab nws yog nyob rau hauv nws cov saw hlau uas siv cov tshuaj hormones txog kev thauj cov teeb liab pib. Raws li qhov tshwm sim, nws tau muab tawm uas nrog rau kev ua yeeb yam zoo rau cov duab thiab kev tsim tawm ntawm lub log tsheb, ib qho kev nco zoo ntawm liab ntawm cov duab tau coj. Tab sis tsis muaj kev tsim txiaj, cov ntsiab lus xws li hauv "cov duab tsis nco qab" eluded los ntawm liab.
Ntxiv mus, cov kws tshaj lij scanned lub hlwb ntawm primates los txheeb xyuas ntau dua lossis ua kom muaj kev ua haujlwm ntau dua hauv kev ua haujlwm ntawm cov chaw ua haujlwm thiab lub cim xeeb chaw. Raws li cov kws tshawb fawb ntseeg, lub network ntawm dopamine cim ntawm lub zog hluav taws xob yog qhov kev ua tiav thiab nco tau ntawm cov duab pom. Yog li, cov duab "tau sau" hauv kev nco txawm tias tsis muaj daim ntawv thov rau kev siv zog no paub qab hau no.
Raws li cov kws tshawb nrhiav, lub suab tuaj yeem hais tau nyob rau hauv tib txoj kev, tab sis qhov tseem ceeb - ntawm ib qho xwm txheej zoo sib xws yog tsis tsuas yog lub cev ntawm tus liab, tab sis kuj yog ib tus neeg. Ntxiv mus, txawm tias lawv tus kheej kev xav uas yog Incentives sab hauv muaj peev xwm daws tau hauv tib neeg lub hlwb. Txawm li cas los xij, cov kws tshawb fawb tau tso tawm cov kev xav ua haujlwm zoo li cov kev tshawb fawb hauv qab no. Cov ntaub ntawv ntawm kev ua haujlwm scientific tau luam tawm nyob rau hauv Neuron magazine.
