As a result, the brain will appear as a hemorrhagic mass of tissue fibers. The cerebral cortex, the portion of the brain responsible for higher order functions in humans (such as movement, thought, speech, etc), will not be present, or functional. The brainstem and cerebellum however, may be spared.
