Bawo kai mutum kwakwalwa nuna kwakwalwa alkyabba. Yana da launin toka al'amari ne kafa ta jijiya Kwayoyin tare da appendages mikawa daga gare su, kuma glial Kwayoyin. An yi imani da cewa karshen yi wani goyon aiki domin neurons da kuma shiga a cikin musayar abubuwa.

A cerebral bawo ne mafi girma, tare da phylogenetic ra'ayi, ƙarami samuwar na tsakiya m tsarin. A kauri daga cikin Layer daga rabi zuwa uku millimeters. A cerebral bawo ne game da goma sha biyu ko goma sha takwas biliyan neurons.

Its total surface an karu da gaban yawa fissures. Sun raba ƙunshi juzu'i na surface na hemispheres da convex gyrus. Kowane yammancin duniya yana hudu lobes. Suna kafa ta uku GROOVES: kaikaice, parietal, occipital da kuma tsakiyar. A sakamakon haka, ya kafa occipital, boko, parietal da frontal lobes.

A karshen aka located a gaban tsakiya sulcus. Parietal lobe da aka iyakance zuwa tsakiyar sulcus a gaban, a kasa - a gefe, parietal-occipital - a baya. Boko lobe ƙuntatãwa a kaikaice tsagi zurfin sama. Occipital lobe a baya na parietal-occipital.

Sama da tarin rubuce-rubuce callosum ne mai farin abu. Ya ƙunshi wani tsinkaya, kuma associative commissural zaruruwa. Bawo yana da biyu-hanyar sadarwa tare da kwance a kasa da CNS via da hawa da sauka hanyoyi. Yana da aka hada da lebur zaruruwa, bayan da hemispheres.

Wasu cortical yankunan daban-daban suna aikin darajar. A daidai wannan lokaci da cerebral bawo aiki a matsayin guda mahaluži. Duk da haka, akwai wani m aikin sarrafawa. Gwaje-gwajen a kan dabbobi sun nuna cewa bayan halakar mutum sassan na bawo, bayan wani lokaci, makwabciyar yankunan fara bauta a matsayin halaka mãkirci. Wannan yanayin da ake dangantawa da high ductility Kwayoyin.
