Overview

Two cerebral hemispheres (left and right)

•Major layers from superficial to deep:

–Surface gray matter (cerebral cortex; neuron somas)

–White matter (axons)–Deep gray matter (e.g., thalamus, basal ganglia)

–Ventricles (4 ventricles)

Cortex means “bark”

•Features include:

–Gyri

–Sulc

–Fissures (deep sulci):

•Longitudinal

-Central 

-Lateral

Layers of the Cerebral Cortex

•Layer I: glia & neurons

•Layer II: small pyramidal cells

•Layer III: large pyramidal cells

•Layer IV: nonpyramidal cells

•Layer V: Betz cells•Layer VI: various cells

•Central

•Lateral
