Ingqondo yomntu iyilungu elimangalisayo, elinamandla okumangalisa imemori, inokulimala, kodwa iyakwazi ukuguqulwa ngokutsha. Ingakanani ubuchopho obukhulu? Nangona ubuchopho bomntu bunesakhiwo esifana nesinye sezilwanyana ezincelisayo, yintoni eyenza ihluke kakhulu ngokobukhulu bayo ngokumalunga nobukhulu bomzimba . Xa kuthelekiswa nobukhulu bemizimba yethu, abantu babanobuninzi obukhulu kunamanye amaninzi.
Ubukhulu beBrain
- Ngokwesisindo, ubuchopho bomntu omdala bunzima bunzima kwi-1300 ukuya ku-1400 amagremu okanye malunga neekhilogram ezi-3 .
- Ngobude, ubuchopho obuphakathi buyi- 15 centimeters ubude .
- Ukuthelekisa, ubuchopho bomntwana obusandul 'usana lubalelwa kuma-350 ukuya ku-400 amagremu okanye kwiikota ezintathu zeepounds.
- Amadoda athambekele ekubeni neengqondo ezinkulu kunabesifazane. Emva kokuba uthathe isisindo somzimba jikelele, ubuchopho bendoda buba malunga nama-gramu ayikhulu kunabesifazane.
- Kubasetyhini, iinxalenye ze-lobe zangaphambili kunye ne-cortex yesigxina (iindawo ezinxulumene nokuxazulula iingxaki kunye nokulawula ngokomzwelo, ziba zikhulu kunazo zonke zamadoda.
- Kwamadoda, i-cortex yepariet (ehambelana nombono wendawo) kunye ne-amygdala (edibaniswa nokuziphatha kwezesondo kunye nolwabelana ngesondo) ziba zikhulu kunabasetyhini.
- I-Neurons yimizimba ekhonza njengeebhloko zokwakha kwengqondo kunye nenkqubo yesantya. Zithumela kwaye zithwale ulwazi, ezivumela iingxenye ezahlukeneyo zobuchopho ukuba zixubane kunye nokuvumela ukuba ingqondo ixubushe kunye neendawo ezahlukahlukeneyo zomzimba. Abaphandi baqikelela ukuba kukho i- neurons ezili-100 zeebhiliyoni kwindawo yengqondo yomntu .
Ngaba Ubunjani Ubunjani Ubunjani?
Ngokucacileyo, akubona bonke abantu abanomlinganiselo ofanayo nobuchopho. Ezinye zikhulu, kwaye ezinye zincinci. Unokuzibuza ukuba ubungakanani bobuchopho bunokudibaniswa neempawu ezinjengokukhubazeka okanye ukuqonda .
Abaphandi baye bafumanisa ukuba kwezinye iimeko ubukhulu bobuchopho bunokudibaniswa nezifo ezithile okanye iimeko zokuphuhlisa.
Ngokomzekelo, abantwana be-autistic bavame ukuba nobuchopho obukhulu (kunye nokuqala kokukhula kwengqondo okungabalulekanga) kunabantwana abangaboniyo. I- hippocampus iyancipha ibe yincinci kubantu abadala asebekhulile besifo se-Alzheimer's disease. Le ndawo yengqondo idibaniswa kakhulu kunye nenkumbulo .
Kuthiwani ngobunkokheli? Impendulo yaloo mbuzo ixhomeke kakhulu kubani ocelayo. Ngokwezinye uphando oluthile lwezifundo ezininzi ezijonge kule ngxaki nguMichael McDaniel waseYunivesithi ye-Virginia Commonwealth University, ubuchopho obukhulu buhambelana nolwazi oluphezulu.
Akunabo bonke abaphandi abavumelanayo nezigqibo zeMcDaniel. Uphando olunjalo luphakamisa imibuzo ebalulekileyo malunga nendlela esichaza ngayo nokulinganisa ulwaphulo-mthetho, nokuba ngaba kufuneka sibhekiselele kubungakanani bomzimba obunxulumeneyo xa senza ulwalamano olunjalo, kwaye yiziphi iinjongo zobuchopho esifanele sijonge xa senza izigqibo ezinjalo.
Kwakhona kubalulekile ukuba uqaphele ukuba xa ukhangelelana ngokwahlukileyo komntu phakathi kwabantu, ukuhluka kobuchopho buyingxaki. Ezinye izinto ezinokuchaphazela okanye ukudlala indima ebalulekileyo ziquka ubuninzi bee-neurons kwingqondo, ezentlalo nakwinkcubeko, kunye nezinye izinto ezahlukileyo ngaphakathi kwengqondo.
