Cerebral Cortex Thin gray-matter covering of the cerebrum; carries on thinking and perceiving Examples Visual Cortex Auditory Cortex Somatosensory Cortex Prefrontal Cortex Gray Matter: No special covering. White Matter: Neurons covered in Myelin sheath (Speeds up Electrical Signal)

Motor Cortex Controls Body Movements Motor Cortex in each hemisphere controls opposite side of body. *Exact Proportions can vary from person to person
