Serotonin-, substance P- and tyrosine hydroxylase-like immunoreactive neurons projecting from the periaqueductal gray to the ventromedial hypothalamic nucleus in the rat.
Direct projections from serotonin-, substance P- and tyrosine hydroxylase-like immunoreactive neurons in the midbrain periaqueductal gray (PAG) to the ventromedial hypothalamic nucleus (VMH) in the rat were investigated by the retrograde horseradish peroxidase tracing method combined with the immunocytochemical technique. Serotonin-, substance P- and tyrosine hydroxylase-like immunoreactive PAG neurons sending their axons to the VMH were distributed in the ventrolateral subnucleus and ventral portion of the medial subnucleus of PAG at the middle and caudal levels.
