Lobar anatomy

Grey & white matter

•Grey Matter / 6 layers , neurons 100 billion / 2-5 mm thickness /+ glial cells / + cortical capillaries

•White Matter / bundles of axons + glial cells + penetrating vessels + fatty myelin sheath – oligodendrocytes + Schwann cells / U- fibers

Limbic system + hypothalamus + pituitary
