Ngakhale maphunzirowa anali makoswe oti azigwiritsa ntchito popanga shuga, kafukufuku watsopano wa asayansi ku Yunivesite ya Briteni akuwonetsa kuwunikira kowala ndi nyimbo kumbuyo kumalimbikitsa kupanga zisankho zowopsa.
Wolemba mu Journal of Neuroscience, ofufuza a UBC anali kuyesera kuti amvetsetse chikhalidwe chamakhalidwe oluluzika komanso zomwe zili zokhudza kutchova juga zomwe zimabweretsa kufunikira kokakamira kwa kutchova njuga kwa anthu ena, zomwe zikufanana kwambiri ndi mankhwala osokoneza bongo.
Pakafukufuku wawo, adapeza kuti makoswe amakhala ngati otchova njuga pomwe mawu omveka komanso opepuka adawonjezeredwa pamachitidwe awo otchova juga kapena mtundu wa "rat kasino". Kafukufuku wowonjezeranso adapeza kuti asayansi adatha kusintha khalidweli poletsa munthu wina kulandira dopamine. Ndizotsatira zomwe zitha kuyala maziko azithandizo zamankhwala osokoneza bongo mwa anthu.
Mu ubongo, dopamine imagwira ntchito ngati neurotransmitter, ndipo ndi mankhwala omwe amamasulidwa ndi ma neurons kapena ma cell amitsempha omwe amatumiza ma cell ku ma cell ena amitsempha. Ubongo umaphatikizapo njira zingapo zophatikizana ndi dopamine, imodzi mwanjira yomwe imathandizira kwambiri pakulimbikitsidwa kuchita zabwino.
"Zinkawoneka, panthawiyo, ngati chinthu chopusa, chifukwa zimawoneka ngati kuwonjezera magetsi ndipo kumveka kungawakhudze. Koma titayendetsa kafukufuku, zotsatira zake zinali zazikulu, "atero Catharine Winstanley, pulofesa wothandizira wa UBC ndi Djavad Mowafaghian Center for Brain Health.
"Aliyense amene adapanga masewera a kasino kapena kusewera njuga adzakuwuzani kuti njira zabwino komanso zabwino zingakupangitseni kuti mukhale otanganidwa kwambiri, koma tsopano titha kuzionetsa zasayansi."
Makasitomala awo "makoswe" amagwiritsa ntchito zotsekemera ngati ndalama ndipo pomwe makoswe amaphunzira momwe angapewere zosankha zowopsa pakuyesera, zonse zidasintha asayansi atabweretsa nyimbo, magetsi oyatsira komanso malankhulidwe. Ngakhale asayansi sanadabwe ndi njira yomwe imagwirira ntchito makoswe, adadabwitsidwa ndi momwe imagwirira ntchito.
Gawo lotsatira poyesa liperekanso kuwunikira. Ofufuzawo atapatsa makoswewo mankhwala omwe adatseketsa chinthu china cholumikizira dopamine chomwe chimalumikizidwa ndi vuto, makoswewo sanakhale ngati otchova njuga. Ndipo ma dopamine blockers anali ndi mphamvu zochepa kwa makoswe omwe amatchova juga popanda magetsi owala ndi nyimbo zachinyamata.
Winstanley adati sakuganiza kuti ndi "ngozi kuti makasino adzazidwe ndi kuwala komanso phokoso," koma amakhulupirira kuti kafukufuku wawo wasonyeza lonjezo lambiri pothana ndi vuto la kutchova juga.
"Tikuganiza kuti tayipanga njira yabwino yogwiritsira ntchito mankhwala osokoneza bongo ndipo tikukhulupirira kuti pophunzira zomwe zimapangitsa nyama kusankha njira zowopsa tidzapatsa chidziwitso chatsopano chamankhwala omwe angadzetse mavuto amtundu wa juga," adatero.
VANCOUVER, British Columbia, Jan. 20 (UPI) - Magetsi oyatsa komanso nyimbo zimalimbikitsa makoswe kuti apange zisankho zowopsa mu "kasino yamakoswe" m'njira zofanana ndi zomwe zimakhudza anthu, zomwe asayansi amati zitha kupereka tanthauzo pakumva kutchova juga.
Asayansi ku Yunivesite ya British Columbia adapeza kuti makoswe amakhala pachiwopsezo, kutchova juga ngati magetsi owala komanso phokoso lalikulu - ndipo anali ocheperako pomwe cholandilira china cha dopamine chimatsekedwa muubongo wawo.
Recopor ya dopamine D3 imayikiridwa kale kuti ndiyofunikira pakukonda mankhwala osokoneza bongo, kutanthauza kuti kafukufuku watsopanoyu amathandizira malingaliro omwe amayamba kugwiritsa ntchito bongo kuti ali ndi chifukwa chachilengedwe.
"Aliyense amene adapangapo masewera a kasino kapena kusewera masewera akutchova njuga angakuwuzeni kuti zomwe mumamva ndizosavuta zimakupangitsani kuchita zambiri, koma tsopano titha kuwonetsa mwasayansi," atero Dr. Catharine Winstanley, pulofesa wothandizana naye ku Dipatimenti ya Psychology ku Yunivesite ya British Columbia, mu cholengeza munkhani. “Nthawi zambiri ndimaona kuti asayansi atengera zaka zam'nyumba zotchovera juga kwazaka zambiri. Sindikuganiza kuti ndi ngozi kuti juga zadzala ndi magetsi komanso phokoso. ”
Mu phunziroli, lofalitsidwa mu magazini ya Neuroscience, ofufuza amaphunzitsa makoswe kusewera masewera ngati njuga. Makoswe ndiye amayenera kusankha pakati pa mphotho zinayi za mphotho ndi njira zamtundu wa juga ndipo adayesedwa poyankha kwawo popanda magetsi ndi mawu akulu.
Pomwe asayansi akuti makoswe amaphunzira kupewa zikhalidwe zoopsa zomwe zimabweretsa chilango, kuwunika ndi kuwamveka zidawapangitsa kuti apitilize kutenga zoopsa zazikulu. Asayansi atapereka mankhwala omwe amaletsa dopamine D3 receptor, kupanga makoswe koopsa kunachepa.
"Izi zolandirira ubongo ndizofunikiranso pakumwa mankhwala osokoneza bongo, chifukwa chake zomwe tapeza zimathandizira lingaliro loti machitidwe owopsa pazochitika zosiyanasiyana atha kukhala ndi vuto limodzi," atero a Michael Barrus, yemwe ndi dokotala pa University of British Columbia.
