Abstract
Uhlalutyo lwangoku lujolise kwi-hypothesis eyenziwa yi-norepinephrine (NE) kunye ne-dopamine (DA) njengeempawu zokufunda. Zombini i-NE kunye ne-DA zisasazwe ngokubanzi kwiindawo ezichaphazelekayo nokumelwa kwehlabathi kunye nokudityaniswa kwezinto ezifakelwayo kunye nokuphuma kweemoto. Zombini zikhutshwa ngamaxesha obutsha kunye nokungaqiniseki, ukubonelela ngeziganeko ezibonakalayo ezifanelekileyo zokuhlaziya umelo kunye nemibutho. Ezi catecholamines zisebenza ngoomatshini be-intracellular eziphathwayo ukuze zisebenze njengemidlalo eyakha imemori. Nangona kunjalo, ngaphandle kokubonakaliswa kwendima ye-NE ne-DA kwimfundo yokufunda kunye nememori yangaphakathi, uninzi lobungqina bokuba zinikezela umqondiso wokufunda buye kwimeko. Obu buthathaka bukhulu bedatha efumanekayo kukusilela kwenkcazo ethile yendlela i-neural circ mod modated ye-NE okanye i-DA ethatha inxaxheba ngayo ekufundeni kuhlalutywa. Ukuchonga imbonakalo enesimo esiphambili (CS) senkuthazo kuya kuququzelela ukuchongwa kwendima yokufunda ye-NE okanye ye-DA. Ukuchaza indlela ummeli we-CS oza kuthi ngayo ukunxibelelana nokuziphatha okufundileyo, nokuba kukwimibutho ehambelana nemvakalelo yokuzivavanya, apho i-CS ifumana ukubaluleka kwenzuzo yomvuzo okanye isohlwayo, ngaloo ndlela kuqhutywa indlela yokuziphatha efanelekileyo, okanye ngokudibana ngqo nemibutho eneemvakalelo zemoto eyimfuneko ukuze ichaze indlela iN kunye ne-DA zithathe inxaxheba ekudaleni imemori. Njengoko kuchaziwe apha, ubungqina obuhambelana nendima yokufunda ngqo ye-NE kunye ne-DA ibonwa kutshintsho lweesekethe zenzululwazi kwimfundo yokuthanda ukuthanda izinto (i-NE), imeko yokuzikhusela (NE), kunye nokuphinda kulungiswe kwi-cortex kwiigundane zabantu abadala (DA). Ubungqina bokuba i-NE kunye ne-DA banegalelo kwimfundo yesiqhelo ngeendlela ezingachazwanga banzi, kodwa iinkcukacha zendima yenkxaso azisekho.
