Qaphela abafundi kuba into eza kuxelwa kweli nqaku inomdla kuwe!
Ukuqhuma okufutshane kokuzivocavoca umzimba kuphucula ukudityaniswa kwememori kubantu abadala abasempilweni nakwabo banengxaki yokuphazamiseka kwengqondo. Ezi ibe ziziphetho zesifundo esenziwe ngoososayensi kwiYunivesithi yaseCalifornia eIrvine (UCI).
Uphando lujolise kwizibonelelo zenkqubo yokusebenza ixesha elide kwimpilo ngokubanzi kunye nokusebenza kwengqondo. Nangona kunjalo, umsebenzi we-UCI ngowokuqala ukuvavanya Iziphumo ezikhawulezileyo zokuzilolonga kwimemori.
Uphononongo lubandakanya ukuthatha abantu phakathi kweminyaka engama-50 ukuya kuma-85 ubudala, kunye nangaphandle kwempazamo yememori. Bababonisa iifoto zendalo nezilwanyana. Kamva Babekwa kwibhayisekile emileyo imizuzu emi-6 kwaye bahamba ngeenyawo kwi-70% yamandla aphezulu.
Emva kweyure, abathathi-nxaxheba banikwa imibuzo yepop ukuze babone ukuba bayayikhumbula na imifanekiso ababeyibonisile ngaphambili. Iziphumo zibonise ukuphucuka okuphawulekayo kwimemori yemifanekiso ebonwayo. emva kokwenza elo xesha lifutshane lokuzilolonga ngokomzimba, kokubini kubantu abadala abasempilweni nakwabo baneengxaki zokuqonda. Iqela elingakhwelanga bhayisekile laqhuba kakubi.
Ngoku abaphandi bajolise ekuqondeni okungcono indlela yokwenza umthambo kuphucula inkumbulo, oko kukuthi, zeziphi izinto ezinokubangela isiseko sebhayoloji.
Abaphandi bakholelwa ukuba Ukuphuculwa kwememori kunokuhambelana nokukhululwa kwe-norepinephrine emva kokuzilolonga. INorepinephrine ngumthunywa weekhemikhali owaziwayo ukuba udlala indima ebaluleke kakhulu kwimodyuli yememori.
Abaphandi bafumanise ukuba amanqanaba e-alpha-amylase ye-salivary, i-biomarker ebonisa umsebenzi we-norepinephrine kwingqondo, inyuke kakhulu kubathathi-nxaxheba emva kokuzivocavoca. Olu nxibelelaniso lwalomelele ngakumbi kubantu abaneengxaki zememori.
Iziphumo ezitsha zibonelela ngendalo kunye nekhuselekileyo engenelelo ngongenelelo kunyango ukuphucula imemori. Ngoluntu olwandayo lokuguga, isidingo sokuphucula umgangatho wobomi kunye nokuthintela ukuhla kwengqondo kubaluleke ngakumbi kunangaphambili.
