Ubuchopho bunezindawo ezihlukene ezinemisebenzi ehlukene. Incane futhi inamandla kakhulu, kodwa ngokuhamba kweminyaka silahlekelwa amandla futhi "isitshalo samandla" sivame ukwehla ekusebenzeni. I-hippocampus yindawo enemisebenzi ehlobene nokulawula imizwa nenkumbulo, kanye ucwaningo lwakamuva kuqinisekisa ukuthi ukuvivinya umzimba kungasiza ekugcineni ukusebenza kahle.
Kungakanani ukuvivinya umzimba esikudingayo ukuze sigcine i-hippocampus isebenza njengoba kufanele?
Olunye uphenyo Ucwaningo lwangaphambilini luthole ukuthi ezinye izindlela zokuziphatha zingenza umehluko, ikakhulukazi imikhawulo yekhalori kanye nokuzivocavoca umzimba. Ocwaningweni olushiwo ngenhla, abacwaningi basikisela ukuthi akukuningi njengoba ungacabanga. Eqinisweni, esimisweni esisodwa sokuzivocavoca ungawubona umehluko.
Ucwaningo, olwanyatheliswa kuyi-Journal of the International Neuropsychological Society, lugxile ku inkumbulo semántica, okuyikhono esinalo lokukhumbula amagama, imiqondo nezinombolo, kanye nemiphumela yokuzivocavoca ku- ukusebenza kwe-hippocampal.
Kulokhu, babe nabahlanganyeli abangu-26, abaphakathi kweminyaka engu-55 nengu-85 ubudala, futhi babanikeza imijikelezo yokuphumula noma imizuzu engu-30 yokuzivocavoca umzimba ngezinsuku ezimbili ezihlukene. Ngemva kwalokho, banikezwa i-MRI futhi bacelwa ukuba bakhumbule amagama abantu abadumile nabangewona odumile.
Ekuhlolweni kwangemva kokuzivocavoca, bathole amaholo ephakeme kakhulu ngokwemibandela inkumbulo, uma kuqhathaniswa nalapho amavolontiya azinikezela kuphela ukuphumula isigamu sehora. Babengenayo nje eyodwa ukwanda kokusebenza ku-hippocampus, kodwa ezinye izingxenye zobuchopho nazo zasebenza.
«Kusukela ezifundweni zangaphambilini, siyazi ukuthi ukuvivinya umzimba okuvamile kungakhuphula inani eliphelele le-hippocampus, futhi isifundo sethu sibonisa ukuthi ngisho nasesikhathini esisodwa sokuzivocavoca singaba nomthelela omkhulu.kusho umbhali oholayo uJ. Carson Smith.
Kungani ukuzivocavoca kudala le nzuzo?
Kunzima ukwazi indlela ubuchopho obusebenza ngayo. Kunamathuba amaningi okuthi kungani ukuzivocavoca kwenza ubuchopho busebenze kangcono. Umbhali wocwaningo uphakamisa ukuthi kungase kuhlobane a ukwanda kwama-neurotransmitters, njenge-norepinephrine ne-dopamine, okwandisa "isilinganiso somsindo wesignali." Lokhu kusho ukuthi amanethiwekhi e-neural angenziwa asebenze ngokuphumelelayo.
Umthelela wokuthuthukisa inkumbulo kubahlanganyeli bocwaningo uthathe cishe ihora elilodwa ngemva kweseshini ngayinye yokujima. Kodwa noma ngabe imiphumela ivame ukuguga kancane ngemva kwaleso sikhathi, ukuqeqeshwa okuvamile kungazuzisa amanethiwekhi e-neural kanye ne-hippocampus. Ake sithi kufana “nokuqeqesha” ubuchopho, njengoba nje siqeqesha imisipha.
«Asinakho ukulandelela isikhathi eside ukuze siqinisekise lokho, kodwa ngokusekelwe kulolu cwaningo nolunye ucwaningo, kungenzeka ukuthi ngokuhamba kwesikhathi, ubuchopho buzivumelanisa nokuzivivinya ngendlela efanayo nomzimba.. Ubuchopho buqina«. Ngalesi siphetho, ubeka isiphetho senganekwane engamanga yokuthi abantu abaya ejimini abanawo ama-neurons amaningi (nakuba besesikwazi lokho).
