Cardiovascular Role of Parvocellular Neurons in the Paraventricular Nucleus of the Hypothalamus

, 1996
The paraventricular nucleus of the hypothalamus contains magnocellular and parvocellular neurons. Some parvocellular neurons project to the spinal cord and are likely to directly influence the sympathetic preganglionic motoneurons.

Circadian rhythm mechanism in the suprachiasmatic nucleus and its relation to the olfactory system

Frontiers in Neural Circuits
Animals need sleep, and the suprachiasmatic nucleus, the center of the circadian rhythm, plays an important role in determining the timing of sleep. The main input to the suprachiasmatic nucleus is the retinohypothalamic tract, with additional inputs ...

Investigating the role of arcuate nucleus and paraventricular nucleus glucokinase in glucose homeostasis [PDF]

, 2020
The brain is as an important regulator of appetite and metabolism. Glucokinase (GK) is a key component of glucose sensing, and is expressed in many glucose sensitive neurones (Rosario et al., 2016, Pocai et al., 2005b).

Roles for γ‐aminobutyric acid in the development of the paraventricular nucleus of the hypothalamus [PDF]

Journal of Comparative Neurology, 2010
AbstractThe development of the hypothalamic paraventricular nucleus (PVN) involves several factors that work together to establish a cell group that regulates neuroendocrine functions and behaviors. Several molecular markers were noted within the developing PVN, including estrogen receptors (ER), neuronal nitric oxide synthase (nNOS), and brain‐derived

A Hypothalamic Oxytocinergic–Sympathetic Axis Couples Anxiety Dysregulation With Impaired Tendon–Bone Repair

Advanced Science, EarlyView.
RCI is associated with functional suppression of oxytocinergic neurons in the PVN. Reduced PVNOXT neuronal activity contributes to altered sympathetic regulation involving the IML–sympathetic chain pathway, accompanied by changes in norepinephrine signaling at the BTI.

HISTOLOGICAL, HISTOCHEMICAL AND IMMUNOHISTOCHEMICAL STUDIES ON THE PARAVENTRICULAR AND SUPRAOPTIC NUCLEI OF THE HYPOTHALAMUS IN THE ADULT NEW ZEALAND RABBITS [PDF]

Assiut Veterinary Medical Journal, 2015
The present investigation aims to give a detailed histomorphological feature of the anterior group of hypothalamus of adult New Zealand rabbits in both sexes. Specimens were prepared to be examined microscopically by using light and transmission electron

Stroboscopic lighting with intensity synchronized to rotation velocity alleviates motion sickness gastrointestinal symptoms and motor disorders in rats

Frontiers in Integrative Neuroscience, 2022
Motion sickness (MS) is caused by mismatch between conflicted motion perception produced by motion challenges and expected “internal model” of integrated motion sensory pattern formed under normal condition in the brain.

Hypothalamic POMC Neurons Gate the Fear‐Feeding Trade‐Off

Advanced Science, EarlyView.
Hungry animals must continually arbitrate between feeding and defensive behaviors when confronted with potential threats. We show that hypothalamic POMC neurons engage CRH‐expressing stress circuits and downstream hormonal responses to coordinate this behavioral selection between competing behaviors.
