The anterior region is also called the supraoptic region. Its major nuclei include the supraoptic nucleus and paraventricular nucleus. There are several other smaller nuclei in the anterior region ...

In a highly novel study, researchers describe how two major neuronal subpopulations in a part of the brain's thalamus called the paraventricular nucleus participate in the dynamic regulation of ...

Figure 1: Mapping and evaluating connectivity of inputs to AgRP ARC neurons. Figure 2: TRH PVH and PACAP PVH neurons provide excitatory input to AgRP neurons. Figure 4: DREADD-mediated ...

Specific hypothalamic nuclei, including the dorsomedial nucleus (DMN), paraventricular nucleus (PVN) and ventromedial nucleus (VMN), serve as control centers for appetite. In animals, lateral ...

These project from the arcuate nucleus to other key hypothalamic nuclei, such as the paraventricular, dorsomedial, ventromedial and lateral hypothalamic nuclei. There are also projections to and ...

They do it involuntarily. The signal that initiates a yawn comes from a particular brain region, the paraventricular nucleus (PVN) of the hypothalamus. It stimulates other brain cells in both the ...

AVP denotes arginine vasopressin, PVN paraventricular nucleus, and SON supraoptic nucleus. When plasma osmolality increases to levels above a physiologic threshold (290 to 295 mOsm per kilogram of ...

Still, low oxygen levels in the paraventricular nucleus (PVN) of the hypothalamus of the brain can induce yawning. Another hypothesis is that we yawn because we are tired or bored. But this ...

This projection activates vasopressin-synthesizing neurons in the magnocellular portion of the paraventricular nucleus (PVN) and the supraoptic nucleus (SON) of the hypothalamus. Blue denotes ...

The researchers then used optical photometry and the calcium sensor GCaMP to continuously monitor activity of two major neuronal subpopulations of the paraventricular nucleus, or PVT, during the ...
