Q. Define cerebral hemisphere tissue?

CEREBRAL WHITE MATTER - The remaining cerebral hemisphere tissue is the deeper cerebral white matter (60% of cerebral volume) which includes myelinated CNS nerve tracts (leading to, or originating from the cortex.)

COMMISSURAL TRACTS (or commisures) connect corresponding areas of the two cerebral hemispheres. Largest commissural tract is the Corpus Callosum (seen above the lateral ventricles in frontal section.)

ASSOCIATION TRACTS carry impulses within a gyrus of a given hemisphere.

PROJECTION TRACTS include nerve fibers which connect cortex to lower CNS centers. At superior margin of brain stem, projection fibers form a compact band called the Internal Capsule (passing between thalamus and basal nuclei). Beyond that point, the Internal Capsule radiates upward to the cerebral cortex (forming the Corona Radiata).
