Imemori zexesha elifutshane

Zexesha elifutshane kwimemori nokugcinwa, kwaye ibonelela ukudlala emva koko ulwazi nokusebenza. Kukho ubungqina bokuba umntu kwaba sisazinzulu waseJamani kaHermann Ebbingausom ngo-1885. Uhlaziya ukusebenza lokwanda oonobumba random, amanani kunye neesimboli emva kokufunda enye, yaye zingqina ukuba olo lwazi njani ngokuchanekileyo ngokutsha ambalwa. Umthamo benkumbulo elifutshane elide kuthatha umlinganiselo kweeyunithi 5-10. Yintoni inkumbulo efunekayo ukuze umntu?

Ipropati iphambili yale memory - ixesha elifutshane, njengoko ingcaciso iya kugcinwa imizuzu embalwa, ngamanye amaxesha imizuzwana. indlela memory elifutshane elide kunokuba nzima, yaye imfundiso emanyeneyo ngalo mbandela ayikho okwangoku. Loluphi ulwazi wena ufune ukufunda, naluphi ugcino iqala kunye neenkqubo electrochemical ezintsokothileyo ebuchotsheni, ngokuba inkumbulo elifutshane elide isekelwe phezu umsebenzi angxamele luvo kunye reentry kwi iziphaluka ezivaliweyo zemithambo-luvo.

indima ebaluleke kakhulu yokuqingqa iindlela memory kudlale ukusetyenziswa nempembelelo zombane phezu koliqele ngobuchopho bomntu. Iziphumo Uphononongo lwabonisa ukuba emva kokuba sesichengeni electric kwenzeka kunesifo retrograde, nto leyo kubonakala kwinto yokuba umntu akabi sayikhumbula nantoni na malunga iziganeko ngaphambi nempembelelo esinjalo ebuchotsheni. A kunesifo efanayo kwenzeka ngenxa Iezothuso enamandla, ukwenzakala kunye zomzimba. Ubude kunesifo retrograde basenokubalisa ukudityaniswa ngexesha memory, oko kukuthi, wobeka phi na kufuneka kwinkumbulo yexesha elifutshane ibe elide kudlule. Ngokuqhelekileyo, memory ukudityaniswa luqala emva kokuba imizuzu 5-10.

Ukufunda imo kunesifo retrograde kulo mzekelo yabantu ziye zanceda izazinzulu ukuqulunqa Cingela indlela imemori elifutshane elide. Yeyona hypothesis wentsimi reverberation amatsheyini ezivaliweyo seli zemithambo-luvo. Kufumaniseka ukuba kwegazi closed imixokelelwane zemithambo (ngakumbi igama Thumela) ihlala imizuzu embalwa, lo gama kugcinwe idatha kulandelelwano elithile pulses. Lwakutsha nje sivela neuron omnye komnye. Kukholelwa ukuba ngexesha intshukumo ifuthe nayiphi isivuseleli ugcina kwenethiwekhi umkhondo.

Hypothesis ngasentla inxulumene ngqo amava ngemihla yaye kubonisa ukuba uqeqesho kufuneka kusenziwa rhoqo - ezininzi izinto ukuqhutywa efundwayo ngokusebenzisa sezingqondweni. Ngenxa yoko, memory elifutshane elide uba ixesha elide.

Zexesha elifutshane imemori - yinto uhlobo lwe memory, nto leyo luphawulwa kwexesha yokugcina elifutshane kakhulu. ulwazi sekholbheki ezilahlekileyo ngenxa yempembelelo yinto yethutyana okanye ngenxa isiziba esitsha elilandelayo ingcaciso efunyenweyo. Ukongeza, memory elifutshane elide kukho inani elincinane ngokwentelekiso lweziqalelo ayidlaleki. Ulwazi kwaphumela igcinwa kwinkumbulo non-nobudlova elifutshane elide memory oluvo kuphela xa umntu uhlawula ingqalelo kuyo ephinda izihlandlo eziliqela. Ngenxa coarsening kweeyunithi zolwazi kuwa phakathi memory elifutshane elide, inani elipheleleyo lweziqalelo oko kwandiswa. Igcina idatha ngaphakathi memory enjalo oluqhutywa fomu ethumayo.

Kwiminyaka yakutshanje, izazinzulu sele usebenza kuphela kwi ingcaciso isenzeko benkumbulo elifutshane elide kunye neendlela zayo, kodwa phezu iindlela zokuhlola kunye noqeqesho. Namhlanje, kukho iimvavanyo ezininzi ezizodwa kunye imisebenzi eza kunceda ubone into kwinkumbulo yakho yexesha elifutshane kunye livavanywa ngokohluka iparameters.
