A Uhlobo olutsha lwe memory phantom?

ezifunyaniswe zizazinzulu ezinkulu zincedise imfundiso phambili inkumbulo, emva abaphengululi bafumanisa ukuba ubuchopho "cwaka" ukugcina inkcazelo, ukudala iinkumbulo waseMelika ezingenazo uhlobo uvaleke.

iintlobo ezimbini memory

Ngokubanzi kuyaqondwa ukuba kukho iindidi ezimbini kwinkumbulo. Eyokuqala kwezi yaziwa ukusebenza inkumbulo. Kokuba usebenze xa ihlaziye ulwazi olutsha, siyigcine engqondweni yakho esijongile, kungekhona ukulibala. Le nkqubo ikakhulu kulawulwa yi-Hippocampus, apho luvo zisebenza rhoqo. Sihlale ingqalelo yethu yokuba uzama ukukhumbula.

Kunjalo, iinkumbulo zexesha elide zigcinwa kwimimandla cortical zobuchopho kwaye wayifihla ezifunyanwa kwimimandla ethile zemithambo, ebizwa engrams. Baba esebenzayo kuphela xa ukususa ezi nkumbulo ezithile.

Uhlobo lwesithathu benkumbulo

Uphando olutsha yenzululwazi kalindixesha Science, iingcaphephe baxele memory lohlobo wesithathu elibhaqiweyo, abathi bona 'ngumsebenzi ophambili memory ixesha elide. " Umahluko omkhulu phakathi le mbono kunye ezimbini eziphambili elibhaqiweyo ngaphambili, kukuba idatha enxulumene uhlobo entsha, ndingekawuboni zigcinwe naphi na kwi ingqondo kwaye ukubizwa njengoko kuyimfuneko.

amava umdla

Iqela wasebenzisa ezisebenzayo livakale magnetic umfanekiso esweni ingqondo-nxaxheba. Izifundo zibonwa uthotho amagama, abantu kunye neefom. Ngenxa MRI algorithm, abaphengululi bakwazi ukuchonga iindlela ezithile umsebenzi kwi uthinte ebuchotsheni, ezinxulumene nganye izikhuthazi.

Ke izifundo eboniswe izibini zezinto ukuba ngaxeshanye ebangela iintlobo ezahlukeneyo ezimbini nokusebenza kwengqondo. Xa nxaxheba bacelwa ukuba baqwalasele enye kuphela kwezi zinto, zingabi sawakhathalela enye, enye yezi patheni wanyamalala, nto leyo ebonisa ukuba sele isusiwe ukusuka inkumbulo esebenzayo.

Izazinzulu zikholelwa ukuba inkumbulo esebenzayo kufuna ukuba ngokuqhubekekayo ezisebenza iiseli zemithambo-luvo. Noko ke, nangona oku, uvavanyo nangoku zigcinwe kwimemori esi sifundo esikhohlakeleyo. iimpendulo Abantu ngayo imibuzo malunga noko bakubonileyo, zibonisa ukuba imifanekiso yezinto isekhona kwicandelo ezinye ingqondo yabo, lo gama kungekho luvo musa zibonisa oku.

"Abantu basoloko becinga ukuba luvo kufuneka ukusebenza rhoqo ukuze sikwazi ukugcina into engqondweni, - wayebacacisela uphando-umbhali Bradley Postl. - Kodwa siye sibone indlela abantu phantse andikhumbuli nto, ayibonisi nayiphi na imisebenzi enxulumene ne-luvo ".

Indlela lohlobo sesithathu memory akukaqondwa kakuhle

Ababhali Uphononongo kwakhona lwafumanisa ukuba, bakwazi ukuvuselela iipateni umsebenzi owenzeka ngexesha xa nxaxheba ekuqaleni swi ingqalelo yabo kwezi zifundo ngokuvuselela ingqondo mandla nosiba olunxulunyaniswa ezi nkumbulo wanyamalala. Kukwenza bacinge izikhuthazi.

Nangona abaphandi abakwazi ukuchaza indlela inkqubo ithatha indawo zifaka yobuchopho, ukuba ukrokrela ukuba imemori phantom ngokusekelwe "esebenzayo-quiescent" Le yindlela apho ulwazi kusindiswa ngandlel kwi leesynapse phakathi iiseli zemithambo-luvo, naxa ezi luvo abazange ukubonisa nayiphi na umsebenzi .
