File:Distribution of relaxin-3-positive neurons and projections.jpg

Summary
Parasagital schematic of the rodent brain displaying the major source of relaxin-3 neurons within the nucleus incertus (NI), while smaller populations are present within the pontine raphe (PnR), periaqueductal gray (PAG), and in a region dorsal to the substantia nigra (dSN). From here, relaxin-3 is trafficked along efferent projections throughout the brain. Image created by Craig Smith.
