Ingqondo ineendawo ezahlukeneyo ezinemisebenzi eyahlukeneyo. Incinci kwaye inamandla kakhulu, kodwa ngokuhamba kweminyaka siphulukana namandla kwaye "isityalo samandla" sithande ukuncipha ekusebenzeni. I-hippocampus yindawo enemisebenzi enxulumene nolawulo lweemvakalelo kunye nenkumbulo, kunye uphononongo lwakutsha nje iqinisekisa ukuba ukuzivocavoca umzimba kunokunceda ukugcina ukusebenza kakuhle.
Ungakanani umthambo esiwudingayo ukuze sigcine ihippocampus isebenza njengoko kufanele?
Olunye uphando Izifundo zangaphambili zafumanisa ukuba ezinye iindlela zokuziphatha zinokwenza umahluko, ngakumbi uthintelo lwekhalori kunye nokuzilolonga. Kuphononongo olukhankanywe ngasentla, abaphandi bacebisa ukuba akukho nto ingako njengoko unokucinga. Enyanisweni, kwiseshoni yokuzivocavoca enye ungawubona umahluko.
Uphononongo, olupapashwe kwiJenali ye-International Neuropsychological Society, igxile kwi inkumbulo semántica, nto leyo sinako ukukhumbula amagama, iikhonsepthi kunye namanani, kunye neziphumo umthambo kwi ukusebenza kwehippocampal.
Ngokwenza oku, babenabathathi-nxaxheba abangama-26, abaphakathi kweminyaka engama-55 nama-85 ubudala, kwaye babafaka imijikelo yokuphumla okanye imizuzu engama-30 yomthambo ngeentsuku ezimbini ezahlukeneyo. Kanye emva koko, banikwa iMRI kwaye bacelwa ukuba bakhumbule amagama abantu abadumileyo nabangengabo.
Kuvavanyo lwasemva kokuzivocavoca, bafumana ngeniso phezulu kakhulu ngokwemiqathango imemori, xa kuthelekiswa naxa amavolontiya azinikele kuphela ukuphumla isiqingatha seyure. Babengenayo nje enye ukwandisa ukusebenza kwi-hippocampus, kodwa ezinye iinxalenye zengqondo ziye zasebenza.
«Ukususela kwizifundo zangaphambili, siyazi ukuba ukuzivocavoca rhoqo kunokunyusa umthamo opheleleyo we-hippocampus, kwaye isifundo sethu sibonisa ukuba nakwiseshoni yokuzivocavoca enye sinokuba nefuthe elibalulekileyo.watsho umbhali ophambili uJ. Carson Smith.
Kutheni le nto umthambo uvelisa olu ncedo?
Kunzima ukwazi indlela ingqondo esebenza ngayo. Kukho inani lamathuba okuba kutheni umthambo wenza ukuba ingqondo isebenze ngcono. Umbhali wophononongo ucebisa ukuba inokuthanani ne ukwanda kwee-neurotransmitters, njenge-norepinephrine kunye ne-dopamine, eyandisa "isignali kwisandi somsindo." Oku kuthetha ukuba uthungelwano lwe-neural lunokwenziwa lusebenze ngokufanelekileyo.
Impembelelo yokuphucula inkumbulo kubathathi-nxaxheba bophononongo ithathe malunga neyure enye emva kweseshoni yomthambo nganye. Kodwa nokuba iziphumo zidla ngokuphela kancinane emva kwelo xesha, uqeqesho oluqhelekileyo lunokuxhamla kwiinethiwekhi ze-neural kunye nehippocampus. Masithi iyafana "nokuqeqesha" ingqondo, njengoko siqeqesha izihlunu.
«Asinalo ixesha elide lokulandela ukuqinisekisa ukuba, kodwa ngokusekwe kolu phononongo kunye nolunye uphando, kunokwenzeka ukuba ngokuhamba kwexesha, ingqondo iqhelana nokuzilolonga ngendlela efanayo nomzimba.. Ingqondo iyomelela«. Ngesi sigqibo, ubeka ukugqiba kwinkolelo yobuxoki yokuba abantu abaya kwi-gym abanayo i-neurons eninzi (nangona sele sisazi ukuba).
