Lately, a center in the hypothalamus has been postulated which would theoretically function as a regulator of blood pressure, acting especially in response to psychic and emotional states. The possible dysfunction of such a center, particularly in an abnormal sensitiveness to psychic or emotional stimuli, could obviously be an important pathogenic factor in the production of clinical "essential" hypertension. In fact, Kahler¹ popularized the concept of a "primary central" type of hypertension due to hyperirritability of a hypothalamic vasomotor center. His evidence, based largely on irregular changes in blood pressure following lumbar . . . [Full Text PDF of this Article]
