The RLVM is primary regulator of the sympathetic nervous system and is notably involved in the baroreflex and It receives inhibitory GABAergic input from the caudal ventrolateral medulla (CVLM).
The RVLM 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. The RVLM is notably involved in the baroreflex. It receives inhibitory GABAergic input from the caudal ventrolateral medulla (CVLM).
