Asymmetry - a ... Hemispheric asymmetry

Zvinozivikanwa kuti kuruboshwe uye kodzero dzevanhu hemisphere akasiyana kushanda, izvo, zvisinei, dzinopindirana. Asymmetry - kutanga iyo tinoberekwa muuropi kwete chete vanhu asiwo mhuka. Uyezve, kuruboshwe hemisphere haisi girazi mufananidzo kurudyi ndiEzekieri. The hemisphere umo mumwe nomumwe ndicho kutaura centre ndihwo. Kazhinji, basa iri reDare rworuboshwe pfungwa nemashoko uye musoro.

Kukurukurirana pakati hemispheres

Pane zvakawanda zvinonakidza zvinhu pamusoro ukama kuripo pakati sezvikamu maviri uropi. Chokutanga, kuruboshwe hemisphere ndiyo nguva dzose zvishoma kupfuura kurudyi. Chechipiri, zvakarurama hemisphere vari refu tsinga fibers kuti kuchiwana kuti kuruboshwe. A kuruboshwe, nekusiyana, rine yakawanda pfupi fibers, izvo asike akwirwe zvishoma munzvimbo.
The asymmetry uropi - a kwacho, paumbwe zvinotora avhareji gumi kusvika gumi apfuura. Dzimwe nguva, ayo kumhanya inogona kukonzerwa nemagene maitiro. Hazvina kushanda isingachengetwi vacheche. Asymmetry - ane vawana unhu. Uyezve, ichiidzwa kuti shoma raidudzwa pakati sadzidza vanhu. Ndiko, ari kudzidza kwauchaita uye kuwana ruzivo itsva uropi zvinova rakaramba asymmetric. Avo vasina mari yakakwana kuteerera dzidzo, sipidhi kuvandudzwa zvakawanda zvinokosha mabasa.

kuvhura asymmetry

Asymmetry - zvakakurumbira kuti ane nguva dzose masayendisiti vanofarira. Asi kune imwe pfungwa yakaramba inoshamisa repamutemo anogona kukonzera yakawanda yokufungidzira, kunyange chakajeka mupfungwa vanhu. Zvakatanga nhoroondo kukura munharaunda iyi Panovhurwa Paul poran ukama pakati kwevanhu matauriro uye kushandisa kurudyi kana kuruboshwe ruoko. Izvi zvakaitika muna 1861, apo masayendisiti akawana kubva murwere wake, uyo akanga achitambura kurasikirwa pakutaura, maronda rworuboshwe hemisphere wouropi.

Uyewo, kubatana pakati penhindi maviri rinoitwa tichibatsirwa rinokosha chiputu Tutsinga tunofambisa mashoko utwu - the corpus callosum. Pamusana kwaari, ivo kushanda noruyanano hwose. Vamwe zvikuru anorwara kushanda vakatakura kwetsinga callosum. Izvi zvaiita kuti kudzidza mberi zvinoitwa kurudyi nekuruboshwe hemispheres.

Kuedza vane paradzanisa-pfungwa

Functional asymmetry anooneka zvikuru gangaidzo nzira. Somuenzaniso, akaonekwa kuti kuruboshwe hemisphere ndiye anokonzera kuvaka akanyatsorongwa, kwakaita kwemasvomhu kukarukureta. Zvinonyatsozivikanwa "anonzwisisa" chero matauriro yakaoma. The rworudyi hemisphere, nekusiyana, anogona chete ziva inonyanya kubatana. Pamusoro mharidzo zvikuru nevakawanda zvinhu - chipunu kana tangle shinda - zvinogona kupa kuti imwe kirasi. Kunakisa rworudyi hemisphere ndiyo rakaisvonaka wezwi iri muchadenga. kuedza kwakaitwa: varwere kutsemura uropi kwezvokurapa akakumbira rworudyi kuunganidza akaitwa mufananidzo. Panguva iyoyo vane yakawanda zvikanganiso zvakaitwa. Izvi zvakanga zvakafanira kuti kuruboshwe hemisphere ndiye anokonzera kurudyi muviri.

kuedza Sperry

Zvidzidzo paradzanisa-uropi yakaratidzawo kuti vanhu vane kodzero kukuvara hemisphere zvakaipa kwazvo nezvatinovavarira muchadenga. Kazhinji, varwere izvi havagoni kuwana nzira kumba apo ivo vairarama kusvika ichi anopfuura makore gumi.
R. Sperry akaratidza kuti panguva kwetsinga yacho corpus callosum , zvinotevera kunoitika: kwemasayendisiti ari maviri muuropi hemispheres dzinotanga kuyerera vakazvimiririra. Kunenge kuti ushande pasina mumwe ndivo vanhu vaviri vakasiyana. Maererano Masayendisiti akawanda, kuti asymmetry - kutanga kuti awana munhu mukufamba shanduka uye chiri kutora.

Agnosia ne pfungwa kukuvara

The asymmetry uropi Chokwadi kunoratidza zvakajeka zvikuru pacharo pakuparwa kuzotadzira mumwe hemispheres. Somuenzaniso, rworudyi hemisphere zvinokuvadza kunogona kukonzera rakasiyana-siyana ainzi agnosia. In chirwere ichi, munhu haagoni kunzwisisa yaizivikanwa apfuura ruzivo. Somuenzaniso, wakaziva agnosia kuti zviso, umo murwere haadi kuziva vanhu yaizivikanwa vanhu. Uye ichi pasinei nokuti kuyeuka zvimwe zvinhu zvenyika uye mamiriro ezvinhu anoramba zvachose node.

Two Mhando mafungiro

Saka, pfungwa asymmetry zvinoreva kuparadzana zvepfungwa mashandiro munzvimbo mbiri huru - spatial uye kuona mafungiro uye husingaoneki zvisingarambiki. To izvi pfungwa, pane anoreva zvakafanana zhinji. Somuenzaniso, imwe tsanangudzo hwemashoko uye non-kutukana mafungiro uyewo discrete uye mawa. Kodzero hemisphere ndiye anokonzera mawa kufunga nokuda vakanzwisisa chinhu pakururama yose zvivako zvayo. The raora ekudzidza maonero zvine musoro nezvatinovavarira hemisphere kuruboshwe. It inoongorora uye zvidzidzo mumwe vanoramba voga.

Basa kuongorora uye kwetunhu

Brain asymmetry ndiye anokonzera kuparadzira mashandiro pakati hemispheres maviri. The akasiya hemisphere ndiye anokonzera Analytical kubudiswa mashoko. It tinoberekwa mafungiro mhando "kubva zvikurukuru mukuru," ndiko induction. Rinonyorerana yose chokubuda mashoko kubva kunze nyika iri musoro hwaro. Kodzero hemisphere ndiye anokonzera zvakadai mupfungwa mashandiro sezvo kwetunhu. Muchikamu ichi vakanzwisisa chinhu ikashandiswa kuva rose. Thinking kunoitwa deductive musimboti - kubva General dzakananga. Kodzero hemisphere ndiye anokonzera nemadimikira, mafungiro yokufananidzira.

Hemispheric asymmetry: vamwe kusiyana

Omumwe kuitika mu kurongwa - ari kushanda vakasiya hemisphere. Kurudyi, nekusiyana, zviitiko zvose kuitika, sokunge panguva imwe chete. Hazvina nezvatinovavarira munguva nokuti iye hakuna chete "pano uye zvino".
The akasiya hemisphere iri nezvatinovavarira kuverenga mumatunhu Somuenzaniso, mashoko pamepu. Right, Ukuwo, runotungamirirwa mune imwe nzvimbo yakadai mukamuri.

Pane musiyano pakati kuparadzira kudzora mashandiro manzwiro ari Hemisférios Cerebrais. The akasiya hemisphere ndiye anokonzera pfungwa, zvakarurama, Ukuwo, nokuti kunaka.

The asymmetry zvakasikwa

Zvinofanira kucherechedzwa kuti Chiitiko iri mubvunzo zvakawanda dzinongoitika zvinhu. Hemispheric asymmetry - the anozviita kuti kwete chete munhu. Kana symmetry rinomiririrwa mune maumbirwo mamorekuru uye crystals, ipapo asymmetry - iri urongwa zvomukati, nemamiriro DNA akamonyoroka. Panewo bvudzi asymmetry.

Research munzvimbo iyi akasiya zvakawanda zvakavanzika. Asi mberi kwesayenzi hakuiti mira. Zvichida zivo ikozvino sokuti pachena, ichava zvisingachashandi zvakakwana masayendisiti ramangwana. Zvichida, masayendisiti zveramangwana achagona chose kukanganisika zvose zvakavanzika chemhando shanduka ari chigadzirwa - uropi hwomunhu.
