Abstract
KUQALA:
Njengomlutha weziyobisi, iimpawu ezinxulumene nokutya okunencasa zinokubangela ukufuna ukutya, nokuba kuhluthi. Nangona kunjalo, nokuba ukuchaphazeleka kwimpembelelo ekhuthazayo yezinto ezinxulumene nokutya yinto ephambi kokutya kakhulu okanye isiphumo sokutya okungalunganga kunzima ukugqiba ebantwini. Sisebenzisa imodeli ye-rodent, siye saphonononga ukuba ukutya okunencasa kakhulu 'kukutya okungenamsoco' kunempembelelo kwiimpendulo kumanqaku abhangqiwe ngomvuzo kuvavanyo lokudluliselwa kwePavlovian ukuya kwisixhobo, kusetyenziswa ubisi oluncindisiweyo oluswiti (SCM) njengomvuzo. Impembelelo ye-hedonic yokusetyenziswa kwe-SCM nayo yavavanywa ngokuhlalutya i-microstructure yokukhotha.
IINDLELA:
Ukuphonononga iziphumo zepateni kunye nobude bexesha lokuvezwa kokutya okungenamsoco, sinikeze iimpuku nge-chow ad libitum rhoqo (ulawulo) okanye i-chow kunye nokufikelela ekutyeni okungenamsoco nokuba yi-2 okanye i-24 h ngosuku kwi-1, 3, okanye i-6 iiveki. Siphinde savavanya indlela ukuchaphazeleka komntu ngamnye ekufumaneni ubunzima obunxulumene nale milinganiselo.
IINKCUKACHA:
Iigundane zibonelele nge-24 h ukufikelela kwi-junk yokutya okungenamdla kwiimpembelelo ezikhuthazayo ze-SCM-paired cue xa zivavanywa zihluthiwe nangona amava abo e-hedonic ekusetyenzisweni komvuzo ayefana nolawulo. Ngokwahlukileyo, iimpuku zibonelele ngothintelo, ukufikelela kwe-2 h ekutyeni okungenamsoco kubonise i-cue generalization phenotype phantsi kweemeko ezigcweleyo, ukucinezela i-lever ngamandla akhulayo ekuphenduleni zombini i-SCM-paired cue, kunye ne-cue engazange idityaniswe nomvuzo ngaphambili. Impendulo ye-Hedonic nayo yayiphezulu kakhulu kwezi zilwanyana ngokubhekiselele kulawulo.
IMISEBENZI:
Ezi datha zibonisa ukuba ipateni yokuvezwa kokutya okungenamsoco iguqula ngokwahlukileyo ifuthe le-hedonic lokutya okunencasa kunye nokuchaphazeleka kwimpembelelo ekhuthazayo yeempawu kwindawo ukukhuthaza iintshukumo zokukhangela ukutya xa kuhluthi, okunokuba yimfuneko ekuqondeni ukutya kakhulu kunye nokukhuluphala.
