See Schematic Illustration in Notes
This is made up of FIBER TRACTS of the CEREBRAL HEMISPHERE (part of the CORPUS STRIATUM).
White Matter
Fig 3.24 p. 68
These are made up of CELL BODIES in the cortex of one hemisphere and pass in a great WHITE SHEET to the other hemisphere.
Commissural Fibers
Fig 3.24 p. 68
These CONNECT ONE PART of the CORTEX to ANOTHER part in the SAME HEMISPHERE.
Association Fibers
This is what the CEREBRAL CORTEX is made of.
Gray Matter
These are MEMBRANES SURROUNDING the entire CNS.
Meninges
Fig 3.4 p. 55
This is located on the DORSAL SURFACE of the CORTEX and somewhat POSTERIOR to the CENTER.
Central Sulcus
This runs POSTERIORLY and DORSALLY on the LATERAL SURFACE of the cortex.
Lateral Fissure
These PROJECTION FIBERS radiate UPWARD toward the cortex FROM the THALAMUS and SUBCORTICAL AREAS (SENSORY).
AFFERENT CorticoPETAL Fibers
These PROJECTION FIBERS project DOWNWARD from CORTEX TO SUBCORTICAL AREAS (MOTOR).
EFFERENT or corticoFUGAL Fibers
These are OUTER Meninges that are THICK, TOUGH and PROTECT.
Dura mater
