Lesions of the Hypothalamic Paraventricular Nucleus and Norepinephrine Turnover in Rats.

Endocrinologia Japonica, 1989
The effects of bilateral lesions of the hypothalamic paraventricular nuclei (PVN), of rats with a mean weight of 260 g body, on eating habits and body weight, as well as on sympathetic nervous system (SNS) activity in interscapular brown adipose tissue (IBAT) were investigated.

Orexin depolarizes rat hypothalamic paraventricular nucleus neurons [PDF]

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2001
Orexins, also called hypocretins, are newly discovered hypothalamic peptides that are thought to be involved in various physiological functions. In spite of the fact that orexin receptors, especially orexin receptor 2, are abundant in the hypothalamic paraventricular nucleus (PVN), the effects of orexins on PVN neurons remain unknown.

Brainstem Origins of Glutamatergic Innervation of the Rat Hypothalamic Paraventricular Nucleus

The Journal of comparative neurology, 2012
Multiple lines of evidence document a role for glutamatergic input to the hypothalamic paraventricular nucleus (PVH) in stress‐induced activation of the hypothalamic‐pituitary‐adrenocortical (HPA) axis.

Hypothalamic paraventricular nucleus activation contributes to neurohumoral excitation in rats with heart failure [PDF]

Regenerative Medicine Research, 2014
Heart failure (HF) is a serious cardiovascular disease and is characterized by exaggerated sympathetic activity. In this paper, we review these limited studies, with particular emphasis on examining the role of the paraventricular nucleus (PVN) in the ...

Short-term cold exposure activates TRH neurons exclusively in the hypothalamic paraventricular nucleus and raphe pallidus.

Neuroscience Letters, 2012
The neuropeptide thyrotropin releasing hormone (TRH) is necessary for adequate cold-induced thermogenesis. TRH increases body temperature via both neuroendocrine and autonomic mechanisms.

The hypothalamus as the central regulator of energy balance and its impact on current and future obesity treatments [PDF]

Archives of Endocrinology and Metabolism
The hypothalamus is a master regulator of energy balance in the body. First-order hypothalamic neurons localized in the arcuate nucleus sense systemic signals that indicate the energy stores in the body.

Optimization of whole-brain rabies virus tracing technology for small cell populations

Scientific Reports, 2021
The lateral hypothalamus (LH) is critically involved in the regulation of homeostatic energy balance. Some neurons in the LH express receptors for leptin (LepRb), a hormone known to increase energy expenditure and decrease energy intake.

The mammalian circadian pacemaker regulates wakefulness via CRF neurons in the paraventricular nucleus of the hypothalamus

Science Advances, 2020
A hypothalamic neuronal circuit mediates circadian-regulated wakefulness in mice. In mammals, the daily rhythms of physiological functions are timed by the central circadian clock located in the suprachiasmatic nucleus (SCN) of the hypothalamus. Although

Paternal Caffeine Exposure Programs Offspring Stress Vulnerability via Sperm Dlk1‐Dio3 Imprinting‐Directed Remodeling of a Novel Neural Circuit

Advanced Science, EarlyView.
The study elucidates that paternal preconception stress can drive offspring hyperresponsivity of the stress system via hypomethylation of a specific DNA region in sperm. This key link is confirmed in a cohort of prospective fathers: the epigenetic alteration is associated with elevated stress hormone levels.

Organotypic slice culture of the hypothalamic paraventricular nucleus of rat

Journal of Veterinary Science, 2007
Organotypic slice cultures have been developed as an alternative to acute brain slices because the neuronal viability and synaptic connectivity in these cultures can be preserved well for a prolonged period of time. This study evaluated a stationary organotypic slice culture developed for the hypothalamic paraventricular nucleus (PVN) of rat.
