Abstract：
:The axonal efferents of neurons of the supraoptic nucleus area were studied by radioautography in the rat after discrete stereotaxic injections of [3H]leucine into this nucleus. Beside a densely labeled pathway running from the nucleus to the posterior pituitary through the internal median eminence, several of the visualized labeled axonal bundles were found to project into various extrahypothalamic regions, including the olfactory bulb, the cortex, the lateral habenula, the subcommissural organ, the amygdala, the mammillary bodies and the locus coeruleus. These results suggest that part of the vasopressin- or oxytocin-containing perikarya located in the supraoptic nucleus constitute the cells of origin of axons which also contain these peptides and which have already been shown to be present in the above extrahypothalamic areas. This also implies that, like the paraventricular nucleus, the supraoptic nucleus is also involved in central extrahypothalamic regulations.
