The supraoptic nucleus is an important "model system" in neuroscience. There are many reasons for this: Some technical advantages of working on the supraoptic nucleus are that the cell bodies are relatively large, the cells make exceptionally large amounts of their secretory products, and the nucleus is relatively homogeneous and easy to ...
They are also found in smaller numbers in accessory cell groups between these two nuclei, the largest one being the circular nucleus. [1] There are two types of magnocellular neurosecretory cells, oxytocin -producing cells and vasopressin -producing cells, but a small number can produce both hormones .

The suprachiasmatic nucleus or nuclei (SCN) is a small region of the brain in the hypothalamus, situated directly above the optic chiasm. It is responsible for regulating sleep cycles in animals. [ 1 ] [ 2 ] Reception of light inputs from photosensitive retinal ganglion cells allow it to coordinate the subordinate cellular clocks of the body ...
The axons of the ipRGCs belonging to the retinohypothalamic tract project directly, monosynaptically, to the suprachiasmatic nuclei (SCN) via the optic nerve and the optic chiasm. [ a ] [ 2 ] The suprachiasmatic nuclei receive and interpret information on environmental light, dark and day length, important in the entrainment of the "body clock".
The paraventricular nucleus of hypothalamus (PVN, PVA, or PVH) is a nucleus in the hypothalamus, that lies next to the third ventricle. Many of its neurons project to the posterior pituitary where they secrete oxytocin , and a smaller amount of vasopressin .
centromedian nucleus [21] parafascicular nucleus [22] lateral nuclear group [13] [23] is replaced by posterior region [24] pulvinar [25] anterior pulvinar nucleus [26] lateral pulvinar nucleus [27] medial pulvinar nucleus [28] inferior pulvinar nucleus [29] lateral posterior nucleus [30] belongs to pulvinar; lateral dorsal nucleus [31] (a.k.a ...
Parvocellular neurosecretory cells are small neurons that produce hypothalamic releasing and inhibiting hormones. The cell bodies of these neurons are located in various nuclei of the hypothalamus or in closely related areas of the basal brain, mainly in the medial zone of the hypothalamus.
