The<unk>  <unk> , also known as the pressor area of the medulla, is a brain region that is responsible for basal and reflex control of sympathetic activity associated with cardiovascular function. Abnormally elevated sympathetic activity in the<unk>  is associated with various cardiovascular diseases, such as heart failure and hypertension. The<unk>  is notably involved in the baroreflex. It receives inhibitory GABAergic input from the caudal<unk>  medulla (CVLM). The<unk>  is a primary regulator of the sympathetic nervous system; it sends catecholaminergic projections to the sympathetic preganglionic neurons in the intermediolateral nucleus of the spinal cord via reticulospinal tract. Physostigmine, a choline-esterase inhibitor, elevates endogenous levels of acetylcholine and causes a rise in blood pressure by stimulation of the<unk> . Orexinergic neurons from the lateral hypothalamus output in the<unk> .
