The ventrolateral medulla consists of arostral ventrolateral medulla (RVLM) and acaudal ventrolateral medulla (CVLM).[2] Neurons in the RVLM project directly to preganglionic neurons in thespinal cord and maintaintonic activity in the sympatheticvasomotor nerves. This activity is inhibited byGABA output from the CVLM.[3][4]
