Metabolic and serotonergic modulation of hypothalamic arcuate nucleus neurones in vitro [PDF]

1. The effects of glucose on the electrophysiological properties of rat hypothalamic arcuate nucleus (ARC) neurones were investigated. Neurones were recorded in 10 mM (hyperglycaemic) and 2 mM (euglycaemic) glucose-containing aCSF.

Neonatal stress is associated with region‐specific changes in mitochondrial respiration and sex‐dependent respiratory instability in adulthood

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal maternal separation (NMS, P3–P12) induces long‐term alterations in respiratory control and region‐specific mitochondrial remodelling along the paraventricular hypothalamus (PVH)–brainstem axis. In adulthood, NMS increases apnoeic events in males, whereas females remain comparatively resistant.

Hypothalamic Neurochemical and Microglial Suppression in Long‐Standing Human Hibernation‐Like Syndrome

Neuropathology and Applied Neurobiology, Volume 52, Issue 6, December 2026.
A rare case of a human hibernation‐like syndrome was associated with preserved hypothalamic anatomy but profound suppression of neuroendocrine and circadian neuropeptide systems. Marked reductions in synaptic and microglial immunoreactivity suggest a suppressed hypothalamic neuron–glial network, despite preserved astrocytic markers, myelination and ...

Efferent connections from the lateral hypothalamic region and the lateral preoptic area to the hypothalamic paraventricular nucleus of the rat

, 1994
The lateral preoptic and lateral hypothalamic regions contain the majority of the cell groups embedded in the fibre trajectories of the medial forebrain bundle on its course through the hypothalamus.

A hypothetic aging pathway from skin to hypothalamic suprachiasmatic nucleus via slow wave sleep

Sleep Science, 2016
Many observations have demonstrated that the hypothalamic neuroendocrine change determines the chronological sequence of aging in mammals. However, it remains uncertain on the mechanism to account for the hypothalamic aging manifestations.

Real‐Time Neurochemical Sensing in Zebrafish: Electrochemical and Fluorescent Approaches

Analysis &Sensing, Volume 6, Issue 6, November 2026.
The use of zebrafish has emerged as a powerful approach for real‐time neurochemical measurements. This review highlights recent advances in electrochemical and fluorescent sensing strategies that enable dynamic measurements in live preparations of this complex vertebrate. These complementary approaches provide new insights into neurochemical signaling,

Reduced Immunoreactivity of Tyrosine Hydroxylase in the Hypothalamic Paraventricular Nucleus of the Seizure Sensitive Gerbil [PDF]

, 2008
We compared the immunoreactivity and numbers of tyrosine hydroxylase (TH) immunoreactive neurons and neuropil in the paraventricular nucleus (PVN) of the hypothalamus between the seizure sensitive (SS) and seizure resistant (SR) gerbils.

Effect of hypothyroidism on the hypothalamic–pituitary–ovarian axis and reproductive function of pregnant rats

BMC Endocrine Disorders, 2018
Background This study aimed to detect changes in hormone levels in the hypothalamic–pituitary–ovarian axis in Sprague-Dawley (SD) rats with hypothyroidism, and identify differences in the pregnancy and abortion rates of female adult rats.

Unraveling the Relationship Between Nr4a2 and Fezf1 Expression in the Developing Feline Telencephalon Within the Genoarchitectonic Context of Claustral and Amygdalar Development

Journal of Comparative Neurology, Volume 534, Issue 11, November 2026.
To define the emergence of the claustral complex in relation to the expression patterns of Nr4a2 and Fezf1 in the domestic cat, a species with more protracted prenatal development than the mouse, we performed a genoarchitectonic analysis. Nr4a2 marked differentiating claustral neurons within the LPall mantle, whereas Fezf1 was broadly expressed in the ...

Altered GABAA α5 subunit expression in the hypothalamic paraventricular nucleus of hypertensive and pregnant rats [PDF]

, 2016
A characteristic of both hypertension and pregnancy is increased sympathetic nerve activity. The level of sympathetic activation is determined, in part, by a tonic GABAergic inhibition arising from the hypothalamic paraventricular nucleus (PVN).
