Notes:
Summary Numerous secretory perikarya were found in the suprachiasmatic, medial preoptio and anterior hypothalamic nuclei of Passer domesticus. The secretory granules of these parvocellular neurons fall into the following ranges: 1000 Å; 1300–1500 Å; 1800–2000 Å. The specialized parvocellular neurons of the rostral hypothalamus form unit-like clusters. They are embedded in a neuropil rich in synaptic structures. Many presynaptic terminals contain dense-core vesicles 〈 1000 Å in diameter. Thus far there is no evidence as to whether the secretory neurons of the anterior hypothalamus project into the median eminence or into other hypothalamic or extrahypothalamic regions. Secretory neurons were also observed in the dorsal portion of the tuberal complex and in the premammillary area.
