Ubongo ntchito. Kwa ena "waya" ubongo afika uthenga?

Ubongo wa munthu , ngakhale lero, akhala weniweni chinsinsi ofufuza. Kaya iwo anatha kuchilingalira. Kotero kuti ena "waya" ubongo amalandira uthenga ndi chiyani chifukwa cha ntchito yake?

Mfundo opareshoni ya ubongo wa munthu

okhwima ubongo wa munthu umalemera pafupifupi theka la kilogalamu, amene "kupsa" mabilioni zana maselo yogwira. Ambiri mwa maselo - ndi manyuroni kuti atumikire monga conduits kwa zikhumbo za mitsempha.

Mmene ubongo umagwirira ntchito? Mfundo za ntchito yake ziri poyerekeza ndi lophimba ntchito magetsi. Manyuroni kungakhale mu "kutali" ndi "pa" boma pamene zilakolako magetsi kudzera m'njira ziwalo.

Anapanga manyuroni mu thupi selo ndi axons zimafalitsa zikhumbo mitsempha. Nawonso axons ubongo ndi cholukanalukana ndi synapses, amene nkhani anasamutsa pakati manyuroni payekha.

Udindo wa mankhwala a mu ubongo

Features wa ntchito ubongo wa munthu amati mankhwala enieni, lotchedwa timene. Kupezeka kwa zinthu monga dopamine kapena wa epinephrine, kumalimbikitsa kutsegula ena ntchito zake. Komanso, m'madipatimenti osiyanasiyana, komanso manyuroni awo, "ntchito" mu ntchito osiyana awo zigawo mankhwala.

Chifukwa ntchito mankhwala ubongo, manyuroni amatha kubereka mlandu wake mphamvu zamagetsi imene zambiri kungakhale pafupifupi 60 Watts. ntchito ubongo, zochokera ntchito magetsi angathe kuyeza ntchito zipangizo zapadera.

Kwa ena "waya" ubongo afika uthenga?

Galimoto chachikulu kufala kwa mudziwe kuti manyuroni wa chingwe msana mutuluka mwa synapses mitsempha. Yerekezerani njira ya chingwe msana akhoza kukhala Mipikisano pakati telefoni chingwe. Kuwonongeka kwa oterowo "chingwe" kungachititse kuti imfa ya ulamuliro anthu pa nthambi munthu aliyense payekha ndiponso thupi lonse. Ndi yonga magetsi zimafalitsidwa ubongo akulamula thupi.

Anyalanyaza pa msana synapses mwachindunji mu ubongo popereka uthenga pa zolandilira Makutu ndi masomphenya. N'chifukwa chake munthu angathe kuona ndi kumva pa ziwalo za thupi lonse.

Ambiri, ntchito ubongo chifukwa cha ntchito nkhani imvi, limene lili padziko ndi imagwiritsidwa kotekisi. A udindo wapadera mu ubongo akuchita zinthu zoyera, amene tiri pafupi kwathunthu wochita axons zikhumbo.

Brain: kapangidwe ndi ntchito

Ubongo wa munthu aumbike ku hemispheres awiri - lamanzere ndi lamanja, amene ali ndi udindo kuphedwa kwa ntchito zina. Choncho, Chigawo lamanja la ubongo wa munthu limakupatsani gulu mudziwe lilinkudza. Nayenso Chigawo kumanzere unapatsidwa makamaka kusanthula deta "ukubwera". Mwachitsanzo, Chigawo bwino limatchula phunziro ndi kumanzere imalongosola ake zizindikiro quality, mbali, etc.

Kwa ena "waya" ubongo afika uthenga? Ofufuza kulandira nyemba magetsi, ubongo bwino amaona ambiri zinthu zodabwitsa komanso mfundo, ri mawonekedwe ndi mtundu. Pa nthawi yomweyo, Chigawo kumanzere ali masamu luso, kalankhulidwe ndi kaganizidwe. Chaka ndi chaka, azasayansi kupeza kugawanika ngati zimenezi za ntchito ubongo ndipo zosiyanasiyana chitsimikiziro watsopano.

Nthano za ubongo wa munthu

Pakali pano, maganizo ofanana ndi munthu ano amatha kugwiritsa ntchito zosaposa 10% ya ubongo. Ngakhale mikangano ambiri ozungulira nkhani imeneyi, pali zambiri lonse umboni wa ntchito anthu a lonse kuthekera ubongo. Ofufuza, ngakhale kuchita ntchito osavuta amafuna kutsegula kwa pafupifupi m'madera onse a ubongo.

Komanso molakwa kuti anthu akhungu kumva bwino olemera poyerekeza ndi woona. Komabe, anthu akhungu angathenso popitilira zambiri otukuka Makutu kukumbukira. Anthu amenewa msanga limatchula magwero chilema, ndipo mwachangu analanda tanthauzo la chinenero.

Ukulu wa ubongo ali mwamtheradi zopanda phindu pa luso aluntha. Kutithandiza kuona chitukuko cha nzeru amakhala yekha chiwerengero cha kugwirizana ubongo pakati manyuroni payekha.

Zosangalatsa za ubongo

Man zovuta awakande nokha. nkhani zonse mu mtima wa ubongo pa maganizo a zikuchitika ku dziko lakunja kuti amalola kuti asonyeze chizindikiro kwenikweni zofunika kwa thupi kuchokera ku mtsinje kwambiri zomverera. Ndipotu, chifukwa ambiri a iwo ndi zochita chikomokere wa munthuyo.

Yawning si wabwino reflex pa achire ku maloto, komanso amalola ubongo mwamsanga boma m'thupimu, chifukwa oxygenation ake yogwira.

Computer masewera kupereka ubongo zina ndi yosangalala chifukwa chododometsa ku ntchito tsiku ndi tsiku, komanso kuphunzitsa kuthamanga ntchito angapo nthawi imodzi. Komanso zabwino kulimbitsa thupi chingwe mu nkhani iyi ndi masewera yogwira, mwachitsanzo Action & oponya mivi, kumene player ayenera kusonyeza gulu lonse la adani awo, amene anachokera ku madera osiyana mu malo ochepa. Kuthandiza pa zosangalatsa zimenezi pafupifupi zimathandiza munthu kuyankha kwa mphezi amadza mofulumira ndi kumwazikana tcheru.

Chitani amathandiza kukhala mu ubongo mawonekedwe abwino. Zonse zolimbitsa thupi bwanji kukula kwa chiwerengero cha capillaries mu ubongo, chomwe chimathandiza bwino kukhutitsa ilo ndi zakudya ndi oxygen.

A nyimbo yosavuta popanda nyumba zovuta nyimbo ndi tanthauzo lapadera n'kovuta kwambiri kuiwala kusiyana kwenikweni mankhwala "wanzeru". chifukwa lili luso ubongo kumanga basi, kabwerebwere zochita ma aligorivimu, sipangakhalenso anamanga ngati nyimbo ndi.

pomaliza

Ubongo wa munthu ndi dongosolo chovuta kwambiri, womwenso kwambiri lonse m'madi- zinchito, zomwe ndi zochokera kutsegula ndi attenuation mabiliyoni ambiri manyuroni.

Kwa ena "waya" ubongo afika uthenga? Udindo wa njira izi ntchito kugwirizana okhudza mitsempha. Aliyense minyewa amachita ngati tosaoneka lophimba magetsi, zomwe lophimba imayendetsa kufala kwa zikhumbo za mitsempha kufunika m'madera a ubongo. Akubwera kuchokera kunja mudziwe dziko pamapeto pake opatsirana kwa hemispheres oziziritsa, kumene kuwunika chomaliza processing.
