neocortex

Wannan shi ne mafi m samuwar a cikin kwakwalwa, mafi evolutionarily sabon. Shi ne ake kira da m hankali na zuzzurfan muhimmanci ga ilimi ayyuka na mutum. A cerebral bawo (neocortex) ne zuwa kashi biyu hemispheres. Su sarrafa kishiyar sashi na jiki. A kowane daga cikinsu asirce iri-iri ayyuka.

Frontal lobe - mafi girma "Head" na kwakwalwa. Yana ba da damar mutum ya zama m, damuarn so, alhakin bincike da kuma shiryawa, mutane tare da keta ma canza irin wannan hadadden halayyar matsayin walwala da annashuwa.
