The caudal ventrolateral medulla (CVLM) is a critical brainstem region that integrates cardiovascular signals and regulates sympathetic outflow through the baroreceptor reflex. Located in the rostral ventrolateral medulla, CVLM neurons receive input from baroreceptors and project to the rostral ventrolateral medulla (RVLM) to modulate vasomotor tone. Cardiovascular autonomic dysfunction is a hallmark of many neurodegenerative diseases. [1]
The CVLM is situated in the ventrolateral medulla oblongata, caudal to the facial nucleus and rostral to the spinal cord. It is bounded laterally by the spinal trigeminal tract and medially by the pyramid. [2]
Cell Types: [3]
Key Molecular Markers: [4]
Afferent Inputs: [5]
The CVLM receives baroreceptor input via the NTS and provides tonic inhibition to RVLM sympathetic premotor neurons. When arterial pressure rises, baroreceptor activation excites CVLM neurons, which in turn inhibit RVLM, reducing sympathetic outflow and lowering blood pressure. [7]
CVLM neurons modulate:
CVLM integrates respiratory and cardiovascular signals, contributing to respiratory sinus arrhythmia and blood pressure variability during breathing.
CVLM coordinates autonomic responses to:
