<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: Isendlalelo: Ucwaningo lokuqala lwe-corpus ngokuqondene nobulili lwalwenziwa ngu-R. B. Bean, isazi sokwakheka komzimba sasePhiladelphia, owasikisela ngo-1906 ukuthi usayizi ohlukile we-corpus callosum ungasho umsebenzi wobuhlakani ohlukile nokuthi kwakukhona umehluko olinganisekayo phakathi kwabesilisa nabesifazane. Mhlawumbe ebonisa isimo sezombangazwe salezo zikhathi, waqhubeka ethi kunokwehluka ngobukhulu be-callosum phakathi kwezinhlanga ezihlukahlukene. Ucwaningo lwakhe ekugcineni lwaphikiswa nguFranklin Mall, umqondisi we-laboratory yakhe. Umthelela omkhulu kakhulu kwakuyi-athikili yeSayensi yango-1982 kaHolloway no-Utamsing ephakamise umehluko wobulili ekwakhekeni kobuchopho bomuntu, obuhlobene nokwehluka kwamakhono okuqonda. I-Time yanyathelisa isihloko ngo-1992 esasikisela ukuthi, ngenxa yokuthi i-corpus ngokuvamile ibanzi ebuchosheni besifazane kunabesilisa, ingase ivumele ukuxhumana okukhulu phakathi kwama-hemispheres - mhlawumbe isisekelo sokuqonda kwabesifazane. Izincwadi zakamuva ezincwadini zengqondo ziye zaphakamisa ukungabaza ngokuthi ngabe ubukhulu be-corpus empeleni buhlukile yini. I-meta-analysis yezifundo ezingu-49 kusukela ngo-1980 yathola ukuthi, ngokuphambene ne-de Lacoste-Utamsing ne-Holloway, akukho mehluko wobulili owawutholakala ngosayizi we-corpus callosum, kungakhathaliseki ukuthi ubukhulu bomqondo womuntu wesilisa bukhulu noma cha. Ucwaningo olwenziwa ngo-2006 kusetshenziswa i-MRI enesiqeshana esincane alubonanga mehluko ekujuleni kwe-corpus lapho kucatshangelwa usayizi womuntu. Umbuzo: Isazi sokwakheka komzimba uR. B. Bean sivela kuliphi idolobha laseMelika?  <response>: EFiladelfiya
