Collateral projections from the subfornical organ to the median preoptic nucleus and paraventricular hypothalamic nucleus in the rat.

It is morphologically demonstrated that the subfornical organ (SFO) projects to the paraventricular hypothalamic nucleus (PVN) and also projects to the nucleus preopticus medianus (POMe), a relay nucleus of indirect projections from the SFO to PVN. However, it remains unknown, whether or not SFO neurons project collaterally to the POMe and PVN. To confirm… CONTINUE READING
