Several theories suggest a role for the ascending activating systems associated with arousal, which is disturbed in encephalopathy and lesions of the thalamus and midbrain. The limbic brain includes these structures and their projections, which reach the forebrain, midbrain, lower brain stem, and the spinal cord limbic systems . Plantar Aspect. Tegmentum: This anterior surface of the midbrain contains numerous structures including the reticular formation, the periaqueductal gray (PAG) matter, certain cranial nerve nuclei, sensory and motor nerve pathways (the corticospinal and spinothalamic tract), the red nucleus, the substantia nigra, and the ventral tegmental area (VTA).
