Asymmetry - ndi ... Hemispheric asymmetry

Amadziwika kuti lamanzere ndi lamanja Chigawo anthu ntchito zosiyanasiyana Komabe, wowonjezera. Asymmetry - chodabwitsa chimene chili chibadidwe ubongo anthu komanso nyama. Komanso Chigawo kulamanzere sikuli galasi chifanizo cha ufulu ndi mosemphanitsa. Chigawo imene munthu aliyense ali pakati kulankhula ndi lalikulu. Nthawi zambiri, ntchito ili ankaimba ndi kunyozedwa ndi zomveka ubongo kumanzere.

Communication pakati hemispheres ndi

Pali zingapo zosangalatsa za maubale omwe alipo pakati pa amachepetsa awiri a ubongo. Choyamba, Chigawo kumanzere ndi zonse zazikulu pang'ono kuposa kumanja. Kachiwiri, mu Chigawo cha kumanja nthawi mitsempha ulusi kuti kulumikiza ku lamanzere. kumanzere A M'malo mwake, lili wambirimbiri ulusi lalifupi, amene analenga kugwirizana m'madera zochepa.
The asymmetry ya ubongo - ndondomeko, mapangidwe a zimafunika avareji zaka khumi ndi khumi ndi asanu. Nthawi zina, liwiro yake chifukwa cha makhalidwe chibadwa. Iwo pafupifupi silinkachitidwa makanda. Asymmetry - ndi kuthi khalidwe. Komanso, imatsimikizirika kuti ndi zochepa kutchulidwa anthu osaphunzira. Ndiko Kuphunzira ndi kupeza zinthu zatsopano ubongo umakhala ndi zambiri asymmetric. Amene samapereka tcheru zokwanira maphunziro, m'mbuyo chitukuko cha ntchito zina zofunika.

Inayambira asymmetry

Asymmetry - Mbali kuti wakhala asayansi chidwi. Koma ina unakhalabe chilli zachinsinsi zimene zingatisocheretse kwambiri osiyanasiyana, ngakhale m'maganizo yowala anthu. Iwo anayamba mbiri ya chitukuko cha dera limeneli ndi kutsegula kwa Paulo Broca ubale kulankhula kwa anthu ndi ntchito za dzanja lamanja kapena lamanzere. Zimenezi zinachitika mu 1861, pamene asayansi apeza kuchokera kwa wodwala wake, amene anali kuvutika ndi imfa ya kulankhula, zotupa lamanzere Chigawo ubongo.

Komanso, kugwirizana pakati pa mbali ziwiri ikuchitika mothandizidwa ndi mtolo wapadera wa manyuroni - ndi corpus callosum. Uyamiko kwa Iye, iwo azigwirizana wonse. Ena ntchito kudwala anagwira kung'ambika callosum. Zimenezi zinathandiza kuphunzira zina makhalidwe a chabwino ndi hemispheres kumanzere.

Zatsopano ndi kugawanika-ubongo

Zinchito asymmetry limapezeka njira paradoxical ndithu. Mwachitsanzo, anaonekera kuti Chigawo kumanzere ndi udindo yomanga kugwirizana zomveka, ndi mawerengedwe masamu. Bwino 'amamvetsa "Mawu aliwonse. Chigawo bwino, m'malo mwake, akhoza amaulula kugwirizana ambiri. Pa ulaliki wa zinthu Ambiri - supuni kapena tangle ulusi - zikhoza aziwachitira kwa kalasi ina. Ubwino wa Chigawo bwino ndi lathu kwambiri danga. kuyesera anali anachita: odwala ndi ubongo kugawanika kwa dzanja zachipatala anapempha ufulu kusonkhanitsa kamangidwe ka chithunzicho. Pa nthawi yomweyo iwo zambiri zolakwa zidalengedwa. Ichi chinali chifukwa chakuti Chigawo kumanzere ndi udindo kumanja kwa thupi.

Zimene Sperry

maphunziro kugawanika-ubongo komanso apeza kuti anthu ndi Chigawo kuwonongeka lamanja zoipa kwambiri zochokera mu mlengalenga. Nthawi zambiri, odwalawo angathe kupeza njira kunyumba kumene iwo ankakhala mpaka zaka zoposa khumi.
R. Sperry anasonyeza kuti pa kung'ambika kwa corpus callosum , zotsatirazi kumachitika: njira ziwiri hemispheres ubongo kuyamba kuyenda paokha. Zikuoneka kuti paokha Chrixitu anthu awiri osiyana. Malinga ndi asayansi ambiri, asymmetry - chodabwitsa kuti muli ndi munthu mu njira ya kusinthika kwa zinthu ndi ndi kupeza.

Agnosia ndi kuvulala ubongo

The asymmetry ya ubongo Ndipotu kumaonekera bwino kwambiri nkhani ya kuwonongeka kwa mmodzi wa hemispheres lapansi. Mwachitsanzo, lamanja Chigawo choipa zingachititse osiyanasiyana otchedwa agnosia. Mu matenda, munthu sangathe kuona bwino mfundo kale. Mwachitsanzo, odziwika agnosia kwa nkhope, imene mtima alibe kuzindikira anthu anthu bwino. Ndipo zimenezi ngakhale kuti anali kukumbukira zinthu zina za dziko ndi zinthu silinasinthe kwathunthu.

Awiri mitundu maganizo

Choncho, ubongo asymmetry amatanthauza kulekana ntchito maganizo m'madera awiri akuluakulu - okhudza malo ndi zithunzi maganizo ndi mfundo chabe. Kuti mfundo imeneyi, pali ofanana matanthauzo ambiri. Mwachitsanzo, matanthauzo yomweyo wapakamwa ndi maganizo sanali wapakamwa komanso apawokha ndi munthawi yomweyo. Chigawo ufulu ndi udindo maganizo munthawi yomweyo, chifukwa cha chinthu anazindikira wosagawanika lonse la katundu wake. Kuchotsedwa kuzindikira kupezeka nawatsimikizira zochokera ku Chigawo cha kumanzere. Iwo kusanthula ndi maphunziro lililonse sakugwirizana payokha.

Ntchito kusanthula ndi kaphatikizidwe

Brain asymmetry ndi udindo kufalitsa ntchito pakati pa hemispheres awiri. Chigawo chatsalira ndi udindo mawunikidwe processing zambiri. Ndi chibadidwe maganizo a mtundu "kuchokera makamaka kwa onse," kapena kuti kupatsidwa ulemu. Iwo anakamba otaya lonse la mudziwe ku dziko kunja pa maziko zomveka. Chigawo ufulu ndi udindo ngati ntchito maganizo monga kaphatikizidwe. Mu gawo ili la chinthu anazindikira amaphatikizidwa mu lonse. Maganizo anachita ndi mfundo deductive - kuchokera onse kuti yeniyeni. Chigawo ufulu ndi udindo zophiphiritsira chabe maganizo, wophiphiritsa.

Hemispheric asymmetry: kusiyana ena

Amaonera zimene zikuchitika mu ndondomeko ya nthawi imene - ndi ntchito ya Chigawo kumanzere. Kumanja M'malo mwake, zinthu zonse kuchitidwe, monga izo zinali pa nthawi yomweyo. Si zochokera mu nthawi: iye pali "pano".
Chigawo anachoka ndi zochokera kuwerenga madera Mwachitsanzo, mauthenga pa mapu. Chabwino, pa dzanja ena, motsogoleredwa mu dera monga chipinda.

Palinso kusiyana pakati pa kufalitsa ntchito kukhumudwa mu hemispheres ubongo. Chigawo chatsalira ndi udindo zabwino mtima, kulondola, Komano, kwa oipa.

The asymmetry m'chilengedwe

Tikumbukenso kuti chodabwitsa mu funso si zachilendo zinthu zambiri zachilengedwe. Hemispheric asymmetry - mwayi wapadera wa anthu osati. Ngati chosokonekera akuyimiridwa mu kapangidwe ka tinthu ndi timibulu, ndiye asymmetry - mu dongosolo la ziwalo, dongosolo la DNA helix. Palinso tsitsi asymmetry.

Research m'dera limeneli anasiya kwambiri cha zinsinsi. Koma sayansi kupita patsogolo alibe kuima. Mwina kudziwa kuti tsopano ngati zoonekeratu, adzakhala lotha kwathunthu kwa asayansi m'tsogolo. Mwina, asayansi za m'tsogolo adzatha kwathunthu kumasulira zinsinsi zonse za zamoyo apamwamba mankhwala - ubongo wa munthu.
