Organization of Central Nervous System Pathways Influencing Blood Pressure Responses During Emotional Behavior

Abstract

A series of studies has demonstrated that the perifornical area of the hypothalamus ("acro-named" HACER, for Hypothalamic Area Controlling Emotional Responses) is responsible for producing the elevated blood pressure and other cardiovascular responses that accompany emotional behavior. The central neural structures providing afferents to the HACER are detailed, and the efferent outflow is analyzed to demonstrate how the HACER produces cardiovascular responses.
