Cardiovascular Role of Parvocellular Neurons in the Paraventricular Nucleus of the Hypothalamus

E Badoer

The paraventricular nucleus of the hypothalamus contains magnocellular and parvocellular neurons. Some parvocellular neurons project to the spinal cord and are likely to directly influence the sympathetic preganglionic motoneurons. Evidence is now accumulating to suggest that those neurons are important in the reflex responses induced by changes in blood volume.
