The most central part of the ventral surface of the forebrain is the optic chiasm, and immediately posterior is the ventral surface of the hypothalamus, including funnel handle (base of pituitary) and papillary body due to damage to the papillary body Thiamine deficiency Involved in the pathogenesis of Wernicke-Korsakoff syndrome.
