Ingane iqala ukufunda ngolimi lwabo lwendabuko esesesiswini sikanina?

Abacwaningi basikisela ukuthi izingane ungezwa umehluko ulimi inyanga ngaphambi kokuba azalwe.

Kucwaningo olwenziwa eMelika

Umsebenzi we ososayensi baseNyuvesi Kansas, imiphumela zazo esanyatheliswa kumagazini i-NeuroReport, kuhlanganisa izithelo omama ababili kweshumi, ababe eziyisishiyagalombili ezithwele. Ukuze wenze lokhu, abacwaningi esetshenziswa MCG (MCG). Lokhu ubuchwepheshe ivumela ukulinganisa kazibuthe eyenziwe umsebenzi inhliziyo kagesi.

Okokuqala nje, ososayensi baye benza amarekhodi amabili - ngesiNgisi kanye Japanese - ngubani ngokuhamba isifundo njalo yakhiqizwa ngoba izithelo. Abacwaningi wakhetha lwalezo zilimi ngoba zihlukile isigqi.

Imiphumela

Ukusebenzisa MCG, iqembu lwathola ukuthi izinga inhliziyo umbungu yakhula lapho wezwa ulimi ezingajwayelekile (Japanese). Uma udlala irekhodi ngesiNgisi (ikhaya kwabesifazane abakhulelwe), fetus kwenhliziyo awushintshanga.

"Imiphumela yethu zisikisela ukuthi ukuthuthukiswa kolimi kungase eqinisweni kwenzeka ngaphambi kokuzalwa, - yena esitatimendeni, umbhali ngalolu cwaningo phambili Yutaka Meany. - Imibungu isethwe ngolimi kamuva bazosebenzisa, ngisho ngaphambi kokuba azalwe, esekelwe izwi amasignali ayatholakala kuwo esibelethweni. Ukuzwela kwama-fetus ukushintsha ulimi isigqi kungenzeka omunye isakhi sokuqala ukuthuthukiswa yokukhuluma. "

Imibono on ukuthuthukisa ulimi

Ngo izifundo langaphambilini, ososayensi batholé ukuthi ekuqaleni ukuthuthukiswa kolimi singenzeka nje kwezinsuku ezimbalwa emva kokuzalwa. Ososayensi bakwazi ukufakazela izingane nozwelo umehluko ijubane phakathi kwezilimi by ukuqapha basabela kubo, isibonelo, isiqalo babubukhulu ngokwengeziwe ukuze imunce ingono.

Kokunye ukuhlola odlule bahlola ukuqashelwa olimi embryonic, kodwa ultrasound isetshenzisiwe le njongo. Ngaphezu kwalokho, abantu ababili abathintekayo ucwaningo, ukukhuluma ngezilimi ezahlukene. Yingakho ososayensi abaye bahluleka ukunquma ingane iphendula omunye umuntu noma olunye ulimi. MCG, esasetshenziswa esikhangisweni se isifundo zakamuva, futhi ingaphezu ebucayi yezinguquko inhliziyo, uma kuqhathaniswa nabangu-ultrasound.

Ngokusho Minaya, umsindo ukuthi umbungu nakuzwayo esibelethweni, akuyona neze into ucace futhi ube mfushane, kodwa ukuze ngenze okuhlukile, ungakwazi uzizwe it. Usosayensi ukholelwa ukuthi le miphumela ezithakazelisa kakhulu cwaningo ayisisekelo yesayensi kolimi.
