Leyo ntlonelo endala malunga nokuphuma ukusela ukuze kubulawe iiseli ezimbalwa zengqondo ingasayi kuba yinto ehlekisayo.
Abantu abatsha abaphuza utywala banokubeka umonakalo omkhulu kumonakalo ebuchosheni babo ngoku kunye nokwandisa ukulahlekelwa kwememori emva kokudala, ngokutsho kophando olutsha. Iintsholongwane zinokuba zisengozini kakhulu ekukhuselweni kwengqondo ngokusela ngokweqile kuneziphuzo ezidala.
Abaphengululi kwiYunivesithi yaseDuke, bafunda ngokukhawuleza utywala kwi-rats ukuthelekisa imiphumo yokusela ngokugqithiseleyo kwiincinci ezincinci nakwezinye.
Izilwanyana zanikwa izidakamizwa zotywala ezifaniswa namaxesha amaninzi okusela utywala kubantu.
Ukusela kakhulu kuyinto Ingxaki
"Asinakhathazeka ngabafundi beekholeji abazisela kuphela esinye isiselo okanye iisiselo ezimbini rhoqo. Umlobi okhokelayo uDkt. Aaron M. White uthe. "Umthamo wokusela utywala wawuphezulu kakhulu ngenxa yokuba asiyazi ukuba yeyiphi i dose efanelekileyo, ngoko sifuna ukubonisa umphumo ukuba umntu ukho."
"Sikholelwa ukuba ubuchopho bentsha buyingozi kakhulu kwimiphumo yobunxilisayo yobunxila kunomntu omdala," watsho. Utywala lufunyenwe luyingozi kwimisebenzi yokufumana ingqondo ejongene nememori nokufunda.
Kamva iRemo yeMali
Abaphengululi banike iiliti ezintshatshulwa ngotywala xa befumana utywala olunye ngolunye usuku, ngoko bafumana usuku. Oku kwaphindwa ngaphezulu kweentsuku ezingama-20.
Emva kwekhefu leentsuku ezingama-20, iiliti zavavanywa ngeendlela zokumisela ukuqonda izakhono zabo ezisisiseko neemoto.
Iingxube zokuxilisa i-rats eziphambili zathi zifaniswa namaqanda amakhulu awanikezwa ngamanzi amaninzi kunye noomntu omdala kunye neengcongolo ezingabonwayo.
Ukusela ngokutsha kuyathinta iMemori yakudala
Kwakungekho nantlukwano kwindlela yokuvavanya phakathi kwamaqela eenkiya ade anikwe utywala obuninzi.
Emva komthamo otywala otywala, i-rat evelele ekuxileni ixilongo ngexesha lokukhulelwa libonisa ukulahleka kweememori.
"Yintoni esiyifumene kukuba iqela eliye lachaphazeleka kakhulu - lenze iiphoso ezininzi - liqela elinesibindi sokubhenjwa kwebinge njengentsholongwane," kusho uMhlophe. "La manzi ayenenkinga enzima ukufumana indlela yabo ngokusebenzisa umzila owawuqeqeshelwa ukuhamba."
Iimiphumo ezihlala ixesha elide lokunwa kwentsha
Abaphengululi baphetha ukuba iziphumo zabo "zibonisa ukuba ukunyanzela i-ethanol ngexesha lokukhula kwentsha kukuphucula ukuphendula kwimiphumo yokukhumbuza imemori ye-ethanol esemdala."
"Iimpembelelo zezifundo zithandwa ngabantu abaphuzayo kakhulu kwaye kaninzi banokuthi banokuchaphazeleka ngenxa yokungaphuzuliswa kweentlanzi kunokuba abantu abadala babe namava afanayo okusela," kusho uDkt. David McKinzie, uprofesa oncedisayo kwi-University of Medicine yaseYunivesithi. "Ukukhathazeka okukhethekileyo kukuba kungenzeka ukuba iziphumo zokusela okungapheliyo zingasenomphumo ongapheliyo."
