Ososayensi kakade ukuthi kungani thina athobe Donsa

Khokha umoya, futhi manje exhale kancane. Lokhu Iqhinga owaziwa elisetshenziswa yoga amakilasi kanye nokusiza wena ekudambiseni isimo esishubile, ngoba esikhathini esiningi okusebenza ngempela. Umzimba wakho azizwa ekhululekile nobuchopho ligcwele umoya-mpilo ophilisayo. Futhi isayensi manje kuphela akwazi ukuthola ukuthi kungani lokhu okwenzekayo.

Iqembu izinzwa elawula isigqi zokuphefumula

It kuvela ukuthi ubuchopho bomuntu kukhona lelincane izinzwa elawula isigqi ukuphefumula. Khona-ke ulwazi mayelana nobuningi ukuphefumula isigqi ukujula ludluliselwa kwesinye zone unesibopho isimo sengqondo. I iqembu labacwaningi basemayunivesithi Stanford University wenza inhlolo-vo ku amagundane laboratory. Ngenxa yalokho, kwatholakala ukuthi namagundane nge "ekhubazekile" nge ukuguquka kwezakhi zofuzo ezikhethekile izinzwa baba sikhululeke kakhudlwana futhi sibe nomuzwa esincishisiwe siqaphile.

"Breathing pacemaker"

Ngaphambili, ngo-90s kwekhulu elidlule, ososayensi benza ucwaningo oluthole isifunda yakhiwa cishe 3000 izinzwa. Leli qembu yezinzwa elise endaweni okuthiwa Pons, cerebellum okuyinto kanye ilungu emuva zobuchopho. Khona-ke, cishe amashumi amathathu eminyaka edlule, kwatholakala ukuthi umoya wethu zingahlanganiswa esimweni sengqondo. Ukutholakala kwaleli qiniso liye labizwa ngokuthi "pacemaker amaphaphu ami." Naphezu ukubaluleka lwati lolutfolakele, ososayensi kwadingeka nokuqonda okuncane mayelana kanjani lesi simiso isebenze.

imizamo okusha ukucacisa isimo

Ukucacisa isimo, ukuze uqale nge, ososayensi kusukela Stanford University bahlola umsebenzi isakhi sofuzo ku brainstem namagundane. zezakhi zofuzo Khona wathola ziye inactivated unqamule ukuxhumana umoya nemizwelo. Ngenxa yalokho, namagundane izakhi 175 izinzwa abantu empeleni abulawe, etholakala 'pacemaker ukuphefumula. "

Imiphumela ukuhlola

Isikhathi sokuqala emva kwenziwa manipulations laboratory amagundane Akabonisanga ushintsho ekuziphatheni. Iqembu locwaningo baqala ukucabanga ukuthi lahluleka ucace. Kodwa ngokushesha kwaba khona okuthile okuthakazelisayo. Mouse naqala ngendlela ehluke kakhulu. Bathula futhi nice. Esikhundleni imisebenzi evamile - amaseli ukunuka, namagundane bancibilika zinakekelwe bona. Abacwaningi baye bathola izinguquko umoya ukuthi kusukela palpitations abe kancane futhi elawulwa.

Lesi siteshi ibhidi

Lokhu ukuziphatha sifana ukuziphatha namagundane abantu okuphumuzayo kakhulu. Kanye unqamukile laboratory igundane izinzwa walahlekelwa ikhono esikhathazayo sokuhlala siqaphile futhi uvalo (wayeka amaseli ukuhogela). Ngokusho ososayensi, lena isiteshi ezimbili. Ngokwesibonelo, amagundane nge izinzwa ekhubazekile ayitholanga amasignali ingozi kanye ukuphefumula elawulwa. Endabeni zabantu lesi simanga usebenza reverse. Uqala ukuphefumula ngokujulile futhi kancane, ubuchopho bakho uthumela izimpawu ukuphumula umzimba. Empeleni, isigqi zokuphefumula uba sine.
