Ubudlelwane boluntu bunceda ukugcina ingqondo

Ukuzivocavoca umzimba kuhambelana neenkalo ezahlukeneyo zempilo.

Izifundo ezininzi ziye zabonisa ukuba ukwenza umthambo rhoqo kunempembelelo yokukhusela kwisifo senhliziyo, isifo seswekile, umhlaza, uxinzelelo lwegazi oluphezulu, kunye nokutyeba, ngokutsho kweNeuroscience News.

Ngokweenkcukacha, iqela labaphandi, kwiYunivesithi yoPhando oluPhambili lweNkqubo yeDynamics yokuguga okunempilo kunye neZiko lokuPhila ixesha elide kwiYunivesithi yaseZurich, banquma ukuphanda intsimi yokuphuhliswa kwengqondo kunye nokuziphatha ebudaleni.

Imisebenzi yenkumbulo kunye nokuzonwabisa

Ukuza kuthi ga ngoku, baphonononge idatha evela kuphononongo olubanzi olwaqalwa kwiminyaka eyi-12 eyadlulayo nguLutz Janke, isazi ngengqondo kunye nonjingalwazi ophumayo kwiYunivesithi yaseZurich, oqhubeka nokulawula iprojekthi kunye noSuzanne Merillat, umphandi oyintloko wophononongo.

Injongo yophando lwangoku kukufunda ubudlelwane phakathi kobunzima be-entorhinal cortex, ukusebenza kwememori, kunye nemisebenzi yokuzonwabisa kubantu abadala abanempilo enengqondo ngaphezu kweminyaka engama-65, ixesha le-7 iminyaka.

Imidlalo kunye nomsebenzi wentlalo

I-entorhinal cortex, emalunga ne-3.5 mm ubukhulu, iyingxenye ye-cerebral cortex kwindawo yangaphakathi ye-lobe yesikhashana kwaye idlala indima ebalulekileyo ekufundeni nasekukhumbuleni. Ikwangomnye wemimandla yobuchopho echatshazelwa kwangoko ekuphuhlisweni kwesifo i-Alzheimer's.

"Iziphumo zethu zibonise ukuba ubukhulu be-entorhinal cortex kubantu abakhutheleyo ngokomzimba nangokwentlalontle ekuqaleni kwesifundo behla ngaphantsi kwexesha lesixhenxe," kusho uJanke.

Abaphandi baye bafumanisa ukuba ubukhulu be-entorhinal cortex bunxulumene ngokusondeleyo nokusebenza kwememori. Njengoko esi sakhiwo sobuchopho sincipha ngexesha lokufunda, ukusebenza kwememori kwehlile.

Qeqesha ingqondo yakho njengesihlunu

"Ukuzivocavoca umzimba kunye nobomi obusebenzayo bentlalontle kunye nabahlobo kunye nosapho kubalulekile kwimpilo yengqondo kwaye kunokuthintela ukuguqulwa kwe-neurodegeneration kamva ebomini," wongezelela uJahnke.

Kuye kwavela ukuba imemori yokusebenza ephezulu ekuqaleni yayinxulumene nokuncipha okuncinci ekusebenzeni kwememori ngexesha lokufunda.

U-Isabelle Hotez, omnye wabaphandi bokuqala kunye noPascal Deschwandin, naye wathi, "Ezi ziphumo zixhasa ingcamango yokuba 'sinogcino lwengqondo,' kwaye ingqondo inokuqeqeshwa kubomi bethu bonke njengezihlunu ukuhlangabezana nokwehla okuhlobene nobudala. .” Ngamanye amazwi, kuluncedo ukuba sempilweni, ngokwasengqondweni nangokwentlalo kubomi bethu bonke, kuquka kamva ebomini.
