IINKCUKACHA: ukulindela umvuzo kunye neyinto elungileyo incike kwiisekethe ezihlukeneyo ngaphakathi kwesekethe enkulu yokuvuza. Ukusebenza okudibeneyo kukhulisa iimpawu ezivuyisayo, kwaye kufaka amava kwiqondo. I-intanethi ye-intanethi = ukulindeleka kwezinto ezintsha.

Abstract
Umvuzo kunye nozuko luyimpawu zokufunda ezinamandla ezithembela ngokuthe ngqo kwiimpendulo ze-dopaminergic midbrain.
Iziphumo ezikhoyo zifumanisa ukuba nangona umvuzo kunye novelwano luyakwazi ukusebenzisana, zombini imisebenzi ingabhalwa ngamacandelo e-neuronal.
Sasebenzisa ukucinga ngombono ophezulu osebenzayo ophezulu (fMRI) ukuhlukanisa iimpendulo ze-neural ukuvuza kunye nozuko ngaphakathi kwendawo yendawo yoluntu ye-nigra / ventral (SN / VTA) eyinkimbinkimbi ukuphanda ukuhlaziywa kwendawo kunye nokuhlanganiswa kwemisebenzi enxulumene nembuyekezo maqela.
Sibonisa ukuba amaqoqo ahlukileyo ngaphakathi kwinqanaba elikhuselekileyo le-SN / VTA ye-median kunye nesabelo esilandelayo se-SN esilungileyo sinomlinganiselo wokulindela umvuzo, wukuqesha inxalenye engaphezulu ye-rostral ye-SN / VTA ye-median yayisetyenzisiwe kuphela.
Ukongezelela, iqoqo le-SN / VTA eliphakathi kwe-Slide / VTA libandakanya intsebenziswano phakathi kokuvelisa kunye nomvuzo apho ubunqwenela bakhetha ukwandisa impendulo-ukulindela iimpendulo. Ukusebenzisana, ngokubhekiselele, kwafana nokungafani nakwiipateni zokuxhuma-nxaxheba kwezi ndawo ze-SN / VTA.
Ngokukodwa, inveli xa kuthelekiswa nokuqhelana nomvuzo wokuqhelisela umvuzo kwandisa ukuhlanganiswa komsebenzi we-SN / VTA emfutshane kunye nemimandla ye-mesolimbic, kubandakanywa i-nucleus accumbens kunye ne-hippocampus, kunye ne-cortex eyona mbonakalo.
Ulungelelwano olusebenzayo lunokugqamisa indlela ama-SN / VTA anxibelelana ngayo anikezela ngolwazi oludibeneyo malunga noveliso kunye nomvuzo, okanye, nokuba kunjalo, indlela yomsebenzi we-SN / VTA ophakathi ungenza ngayo imimiselo yeememori kwiziganeko zorhwebo ezihambelana nemivuzo.
