VI. Cerebrum - two hemispheres containing 5 different lobes A. General Features 1. cerebral cortex - (gray matter) surface, cell bodies 2. cerebral tracts - (white matter) beneath, axons 3. gyri/convolutions - ridges of cortex 4. fissures - deep grooves/valleys between gyri 5. sulci - shallow grooves/valleys between gyri 6. longitudinal fissure - divide right/left hemispheres 7. corpus callosum - tracts connecting right/left 8. falx cerebri - dura mater in long. fissure B. The Lobes of the Cerebral Cortex 1. frontal lobe - under frontal bone a. central sulcus - frontal <-> parietal i. precentral gyrus - anterior, motor area ii. postcentral gyrus - post., sensory area b. lateral sulcus - frontal <-> temporal 2. parietal lobe - under parietal bone a. parieto-occipital sulcus
