Chikondi poyang'ana koyamba .. Zimachitika bwanji ndi kugwirizana kwake mu ubongo

Chikondi poyang'ana poyamba, ndi chenicheni kapena chinyengo, chimachitika bwanji ndi zomwe zimagwirizanitsa mu ubongo ndi chowonadi cha kupitiriza kwake, kafukufuku watsopano wochokera ku American "Yale University" wapeza kufotokozera kwasayansi kwa sayansi. kufalikira kwa neural kuyankha m'madera ambiri a ubongo omwe amapezeka pamene maso amakumana Anthu awiri ali ndi chiyanjano, kaya ndi ubwenzi, kukhudzidwa maganizo, kapena ngakhale kumverera kosautsika, malinga ndi zomwe zinafalitsidwa ndi Neuroscience News.
"Pali zizindikiro zamphamvu kwambiri muubongo zomwe zimagwirizana ndi chikhalidwe cha anthu," adatero Steve Chang wa Yale University, pulofesa wothandizira wa psychology ndi neuroscience, membala wa Wu Cai Institute ndi Kavli Institute of Neuroscience, ndi mtsogoleri wa phunziroli. wolemba.

Chochitika chochotsa tanthauzo m'maso pakati pa anthu awiri chalembedwa muzojambula ndi zolemba kwazaka masauzande ambiri, koma asayansi akhala akuvutika kuti awulule momwe ubongo umakwaniritsira izi.
Kafukufuku wambiri adachitikapo kale pa neurobiology of cognition of social cognition, nthawi zambiri poyang'ana muubongo wa anthu omwe amawawonetsa zithunzi zosasunthika, monga nkhope zokwiya kapena zachimwemwe, mawonekedwe achindunji, kapena kupewa kuyang'ana wina. Komabe, zinali zovuta kuthana ndi kuyanjana kwaubongo wa anthu awiri pawokha chifukwa amachotsa zidziwitso mwachangu komanso mogwirizana m'maso mwa mnzake.

Chatsopano n'chakuti ofufuza a labu a Zhang adagonjetsa vutoli poyang'anira ntchito za ubongo wa anyani kwinaku akutsata malo a maso a nyama, zomwe zimawathandiza kuti azijambula gulu lalikulu la ma neuroni pamene nyamazo zimayang'anizana.
"Nyamazo zinkangotenga nawo mbali pazokambirana pomwe ofufuzawo adawunika kuwombera kwa mitsempha," adatero Zhang. Chofunika kwambiri n’chakuti palibe ntchito imene inapatsidwa, choncho zinali kwa iwo kusankha mmene azidzachitira zinthu komanso nthawi yake.” Ofufuzawo anapeza kuti magulu enaake a minyewa yoyenderana ndi anthu amawombera m’madera osiyanasiyana a muubongo nthawi zosiyanasiyana akamakumana maso.
Mwachitsanzo, gulu limodzi la ma neuron limawombera pamene munthu wina ayang'ana maso, koma osati pamene munthuyo akuyang'anitsitsa mnzake.
Gulu lina la ma neuron linali logwira ntchito pamene anyaniwo ankaganiza zoti apitirize kuyang'ana m'maso kumene winayo anayambitsa.
Chochititsa chidwi n’chakuti, poyang’anitsitsa munthu wina, ma neuron ena amadziŵa mtunda wofanana ndi maso a munthu wina, koma atayang’ana, gulu lina la minyewa limasonyeza kuyandikana kwa munthu winayo.
prefrontal cortex ndi amygdala
Madera a muubongo komwe kuyambika kwa neural kudachitika adapereka malingaliro amomwe ubongo umawunikira tanthauzo la kuyang'ana. Chodabwitsa n'chakuti, gawo la maukonde, lomwe linayambitsidwa panthawi yolumikizana ndi anthu, linaphatikizapo prefrontal cortex, mpando wa maphunziro apamwamba ndi kupanga zisankho, komanso amygdala, pakati pa maganizo ndi kuunika.
"Madera ambiri mkati mwa prefrontal cortex, kuwonjezera pa amygdala, amalembedwa kuti aziyankha pazosankha zomwe anthu amakumana nazo, zomwe zikuwonetsa kufunikira kwa gawo lowoneka bwino panthawi yochezera," adatero Zhang.

Zimadziwikanso kuti madera awa mu ma prefrontal ndi amygdala network omwe amayatsidwa panthawi yolumikizana ndi anthu amasokonekera pakachitika zochitika zapagulu, monga autism, kutsimikizira kufunika kwawo pakukwaniritsa malingaliro olumikizana.
Zhang adawonjeza kuti kuyanjana koyang'anizana ndi anthu kumapangitsa kuti pakhale mgwirizano, ndipo maukonde a lobe yakutsogolo ndi amygdala angapangitse izi kuchitika, kufotokoza kuti "chifukwa choti ma neuron omwe amalumikizana nawo amapezeka kwambiri muubongo amalankhulanso ndi ubongo. kufunika kwa makhalidwe abwino kuyanjana ndi anthu.” “.
