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 ...
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 ...
Magnocellular neurosecretory cells are large neuroendocrine cells within the supraoptic nucleus and paraventricular nucleus of the hypothalamus.They are also found in smaller numbers in accessory cell groups between these two nuclei, the largest one being the circular nucleus. [1]

Neurons of the lamina terminalis project to the supraoptic nucleus and paraventricular nucleus to regulate the activity of vasopressin-secreting neurons. [9] In a situation of lowered blood volume, secretion of renin by the kidneys results in the production of angiotensin II , which stimulates receptors in the VOLT and subfornical organ to ...

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.
Ventromedial nucleus of the hypothalamus (VMN) has long been considered as a sexually dimorphic nucleus. It is an important region for regulating the sexual responses in female rodents. The neurons within VMN have significant estrogen-dependent functional and structural plasticity. The synaptic organization of the VMN is sexually dimorphic.
