Noradrenaline

Noradrenaline ndi mahomoni opsinjika maganizo ndipo ndi chinthu chonyamulira chomwe chimagwirizana ndi kuyankha kwa thupi kapena kuthawa. Noradrenaline imamangirizanso ku adrenaline, ndipo milingo yake imatha kuchulukirachulukira panthawi yamavuto, koma imathandizanso kusungabe chidwi.

Munthu “angaganize kuti kugona n’koyenera, kenako n’kudzuka,” anatero wofufuza wina, Pulofesa Celia Kirby wa pa Center for Translational Neurological Medicine. Koma kugona n’kovuta kwambiri kuposa mmene munthu amaonera. Zasonyezedwa kuti noradrenaline imapangitsa munthu kudzuka maulendo oposa 100 usiku. Ndizochitika mwachibadwa pamene mukugona."

Mwaukadaulo kudzutsa ubongo

Ngakhale noradrenaline mwaukadaulo imapangitsa kuti ubongo udzuke maulendo oposa 100 usiku, anthu samawona ngati akudzuka.

Malinga ndi minyewa, munthu amakhala wogalamuka, akutero wolemba mnzake wina, Mai Andersen, chifukwa zochita zaubongo panthawi yaifupi kwambiri zimakhala zofanana ndi zomwe ali maso. Koma nthawi ino ndi yaifupi kwambiri moti wogonayo sazindikira.”

Ngakhale ofufuzawo adachita zoyeserera pa mbewa, zotsatira zawo zitha kumasulira kwa anthu, chifukwa zimangoyang'ana njira zoyambira zamoyo - njira zomwe zimachitikira nyama zonse zoyamwitsa.

kugona tulo

Pulofesa Maiken Nedergaard, wofufuza wamkulu pa kafukufukuyu, akuti zomwe zapezedwa zatsopanozi ndi gawo lofunikira kwambiri la chithunzithunzi kuti timvetsetse zomwe zimachitika muubongo nyama zoyamwitsa zikagona, ponena kuti "pachimake cha gawo la tulo chomwe chimatipangitsa kudzuka ndikupumula komanso tikumbukire zomwe tidaphunzira tsiku lapitalo zapezeka." Tinapeza kuti mbali yotsitsimula ya tulo imayendetsedwa ndi mafunde a noradrenaline.”

Pulofesa Nedergaard akuwonjezera kuti "Kudzutsidwa kwakufupi kwambiri kumapangidwa ndi mafunde a norepinephrine, omwenso ndi ofunika kwambiri kukumbukira. Munganene kuti kudzuka kwakanthawi kochepa kumapangitsa ubongo kukhala wokonzeka kusunga kukumbukira mukagonanso.”

Ofufuzawo anaika ulusi wopangidwa ndi magalasi opangidwa ndi magalasi opangidwa ndi ma genetic osinthidwa ma "photoreceptors" muubongo wa mbewa zoyesa.Zingwezo zidalumikizidwa ndi zingwe, kuphatikiza gwero la kuwala kwa LED.

Kenaka, ofufuzawo anayeza milingo ya noradrenaline pamene nyama zimagona ndikuziyerekeza ndi ntchito zamagetsi mu ubongo wawo kuti azindikire kuchuluka kwa noradrenaline.

"Supermemory"

Kenako ofufuzawo adayesa kukumbukira pogwiritsa ntchito zida zoyikidwa kuti awonjezere matalikidwe a mafunde a noradrenaline ndikuwongolera kukumbukira kwa nyama.

Kafukufuku wam'mbuyomu wasonyeza kuti noradrenaline, yomwe imagwirizanitsidwa ndi kupsinjika maganizo, imakhala yosagwira ntchito panthawi yogona. Chifukwa chake, ofufuzawo adadabwa kudziwa momwe noradrenaline imagwirira ntchito panthawi yatulo.

Kirby akuti zotsatira zake zikuwonetsa kuti mbewa, zomwe zidakumana ndi zochitika zapamwamba komanso zotsika za noradrenaline, zinali kuchita bwino komanso "zodabwitsa kwambiri," zomwe zikutanthauza kuti mphamvu ya noradrenaline imapangitsa kugona komwe kumakhudza kukumbukira.

Antidepressants

Zotsatira za phunziroli zimapereka malingaliro atsopano pa ntchito ya noradrenaline mu antidepressants. Kirby akufotokoza kuti “mitundu ina ya mankhwala ochepetsa kupsinjika maganizo imawonjezera mlingo wa noradrenaline m’thupi, zimene zimawonjezera chiwopsezo cha kusakhoza kugona bwino, ndiyeno zotsatira za phunzirolo zimasonyeza kuthekera kwa mankhwala ena ochepetsa kupsinjika maganizo amene amakhudza kugona ndi kukumbukira, ndipo anazitcha zimenezo. "Kupanga mankhwala kuyenera kufunidwa. Simakhudza mafunde a noradrenaline panthawi yatulo m'tsogolomu."
