Izinkumbulo zingacasula kakhulu. Thatha, isibonelo, amasosha amiswe ezindaweni zempi abuyele ekhaya; bavame ukuhlushwa ukucindezeleka kwangemva kwenhlekelele futhi abanye bangaze bazibulale.
Kungenzeka ukuthi abacwaningi basePuerto Rico bathole indlela yokunciphisa ukwesaba okuhambisana nezinkumbulo ngokujova ikhemikhali lemvelo ngqo ebuchosheni.
ukufunda ngokuqothulwa. Isibonelo: abacwaningi bangafaka ukwesaba okufundwayo kumagundane elebhu; lapho kukhala insimbi kusetshenziswa ugesi kumagundane.
Ngemuva kwesikhashana, amagundane esaba ubuhlungu obuhambisana nokukhala. Abaphenyi bangayihlehlisa le nqubo ngokufunda ngokuqothulwa, okuphikisana ngqo; Insimbi iyakhala, kepha ukushaqeka kukagesi akusetshenzisiwe. Uma lokhu kuphindwa kaninginingi, amagundane angakukhohlwa lokho kwesaba.
Abaphenyi baseYunivesithi yasePuerto Rico babefuna cisha ukwesaba ngamakhemikhali, kunokufunda okuphindaphindwayo. Ukwenza lokhu, ikhemikhali lemvelo elaziwa ngokuthi "Isici se-neurotrophic esuselwa ebuchosheni" (BDNF) kuma-cortices angaphambili wamagundane. I-BDNF ibandakanyeka ezinhlotsheni ezahlukahlukene zokufunda, kufaka phakathi ukufunda ngokuqothulwa. Abaphenyi babenethemba lokuthi ukwandisa inani le-BNDF ngokungekho emthethweni kungaqeda ukwesaba insimbi.
Ekuhlolweni, amagundane abekwe isimo sokwesaba ukukhala ngokushaqeka kukagesi. Ngakusasa, esikhundleni sokubeka amagundane ekuqothulweni kokufunda, iBDNF yajojelwa eqenjini lamagundane. Kwakukhona iqembu lamagundane wokulawula okungafakwanga lutho kuwo. Ngakusasa, abaphenyi baqala ukushaya insimbi. Njengoba bekulindelwe, amagundane okulawula aqine, elindele ukushaqeka. Esikhundleni salokho, iqembu lamagundane elinikezwe i-BDNF alizange liguqule indlela yabo yokuziphatha ejwayelekile (ungabuka ividiyo ekugcineni kwalesi sihloko).
Amagundane ayesenenkumbulo yawo yokubhuza nokushaqeka, kepha ukwesaba okuhambisana nakho kuncishiswe kakhulu. Njengoba kunje, lolu cwaningo lungaba nemithelela ebalulekile ekwelapheni ukukhathazeka kanye nengcindezi yangemva kwenhlekelele.
