Ukulala Kusisiza Ukukhumbula Esikudingayo

Amajaji abuyile futhi isinqumo sikhona. Ukugcinwa kwesikhathi eside kwezinkumbulo kwenzeka ngesikhathi sokulala. Akuyona nje inqubo yokwenziwa kokukhohlwa - lapho izinkumbulo zesikhashana ezingenamsebenzi noma ezingenasisekelo ziphela ekungacacini. Ukugcinwa kwememori ngesikhathi sokulala kuyinqubo esebenzayo. Abaphenyi abaningana bakhombisile ukuthi izethulo ze-neuronal zezinkumbulo ziyaphinda zisebenze ngesikhathi sokulala, kube sengathi ubuchopho buphinda ukurekhoda. Ukuphinda kudlalwe kubalulekile ekugcinweni kwememori yesikhathi eside, mhlawumbe ngoba kusabalalisa kabusha ukuxhumana kwe-neuronal kusuka kwimemori yesikhashana kuya kumasayithi wokugcina wesikhathi eside ku-neocortex.

Ingqondo yakha futhi ihlele kabusha izifunda zayo lapho silele. Noma kunjalo, kusobala ukuthi kumele kube nokukhetha okuthile okuhilelekile. Iningi lemininingwane emikhulu engena kithina nsuku zonke ifakwe ikhodi okwesikhashana; namhlanje sikhumbula esasikudla kwasekuseni nalapho sipake khona imoto. Kepha njengoba silele, iningi lolo lwazi luyalahlwa. Ngakho-ke esikwaziyo namuhla kungalahleka kusasa-- noma cha. Yize okuningi kwalokho okufakwe kwimemori kuchithwa, "izinto ezibalulekile" zihlala. Asikhohlwa ukungavumelani nomlingani noma inhlolokhono yomsebenzi ethembisayo.

Umbuzo obalulekile uthi, Ngabe ubuchopho "bunquma kanjani" ukuthi benzeni nokuthi yini okufanele bayilahle? Kuleli sonto eledlule, isifundo esibalulekile sidonse iso lami, esingasisiza ekugcineni siphendule lowo mbuzo. Abaphenyi baseJalimane bathole ubufakazi bokuthi ubuchopho buhamba ngezinkumbulo ngesikhathi sokulala futhi ngokukhetha kugcina lezo ezifanele kakhulu. Ucwaningo, olushicilelwe ku- Ijenali yeNeuroscience , iphetha ngokuthi ubuchopho buhlola ulwazi olususelwa kulokho okulindelekile esikhathini esizayo. Ngemuva kokulala kahle ebusuku, sikhumbula imininingwane kangcono lapho sazi ukuthi izosiza ngokuzayo.

Kuwo womabili amaqembu, uhhafu wamavolontiya atshelwa ngokushesha kulandela imisebenzi yokufunda ukuthi bazohlolwa emahoreni ayi-10. Eqinisweni, bonke ababambiqhaza bahlolwa ngokuhamba kwesikhathi, kepha kuphela ingxenye yabo eyayilindele ukuhlolwa. Futhi, ezinye, kepha hhayi zonke, zamavolontiya avunyelwe ukulala phakathi nesikhathi abafunda ngaso imisebenzi nesikhathi abathathe ngaso izivivinyo.

Ukulala kuqhathaniswa nokuphaphama kuveze ukuthuthuka okuqinile ekusebenzeni kokuhlolwa kuphela uma ngabe izifundo zazazisiwe mayelana nokuhlolwa. Ezifundweni ezazingaziswanga, ukubuyisa ngemuva kokulala kwakungcono kakhulu kunangemva kokuvuka. Ukugcinwa ngezikhathi zokuvuka akuzange kuphazanyiswe ukulindela ukuhlolwa. Ngamafuphi, kuphela abantu abalele futhi abazi ukuthi isivivinyo siyeza babekwenzile ukukhumbula okuthuthuke kakhulu. Ngakho-ke, ukulindela nje ukuthi inkumbulo izoba wusizo ngokuzayo kubanga ukulala ukuhlanganisa inkumbulo.

Abaphenyi baphinde baqopha ama-electroencephalograms (EEGs) avela kubantu abalele. Izihloko ebezilindele ukuhlolwa zibonise ukwanda okunamandla kokuhamba kancane komsebenzi ngesikhathi sokulala kwabo okuhamba kancane. Ukusebenza kancane kwegagasi ababambiqhaza abalele babenawo, kwaba ngcono inkumbulo yabo ngesikhathi sokuhlolwa. Abazelwe nabasebenza nabo bacabanga ukuthi le nqubo ingafaka okungenani izingxenye ezimbili zobuchopho. I-cortex yangaphambi kobuchopho ibonakala "ithega" izinkumbulo ezithathwa njengeziwusizo esikhathini esizayo, kuyilapho i-hippocampus ihlanganisa lezo zinkumbulo ngesikhathi sokulala.

"Imiphumela yethu ikhombisa ukuthi ukuhlanganiswa kwememori ngesikhathi sokulala empeleni kubandakanya inqubo eyisisekelo yokukhetha enquma ukuthi yiziphi izingcezu zolwazi losuku ezithunyelwa ekugcineni kwesikhathi eside," kusho uBorn. "Imiphumela yethu ikhombisa nokuthi ulwazi olufanele izidingo zesikhathi esizayo lukhethwe kakhulu ukuze ligcinwe."
