It is unclear how the brain interprets these signals. O-GlcNAc transferase (OGT) catalyzes the posttranslational modification of proteins by O-GlcNAc and is regulated by nutrient access. Here, we show that acute deletion of OGT …

The paraventricular nucleus (PVN, PVA, or PVH) is a nucleus in the hypothalamus. Anatomically, it is adjacent to the third ventricle and many of its neurons project to the posterior pituitary. These projecting neurons secrete oxytocin and a smaller amount of vasopressin, otherwise the nucleus also … See more The paraventricular nucleus lies adjacent to the third ventricle. It lies within the periventricular zone and is not to be confused with the periventricular nucleus, which occupies a more medial position, beneath the See more The PVN receives afferent inputs from many brain regions and different parts of the body, by hormonal control. Among these, inputs from neurons in structures adjacent to the anterior wall of the third ventricle (the "AV3V region") carry information … See more The PVN contains magnocellular neurosecretory cells whose axons extend into the posterior pituitary, parvocellular neurosecretory cells that project to the median eminence, ultimately signalling to the anterior pituitary, and several populations of other … See more • Hall JE, Guyton AC (20 May 2015).

Web1. Introduction. Oxytocin (OT) and arginine-vasopressin (AVP) are important chemical signals that act in the brain to regulate a large number of adaptive social behaviors and in the periphery to coordinate a diverse group of physiological functions [1; 2].Although the chemical structures of OT and AVP as well as their receptors are quite similar, there is … Webbrain: [noun] the portion of the vertebrate central nervous system enclosed in the skull and continuous with the spinal cord through the foramen magnum that is composed of … WebOne way to get the PVN if the brains are frozen would be mount it on a cryostat and take a tissue punch of the region after slicing down the level you want, or just before, they make … equivalent of a megagram
