Prolonged stress alters the PC1/PC2 ratio in the rat lateral hypothalamus, implicating impaired orexin maturation [PDF]

open access: yesIranian Journal of Basic Medical Sciences
Objective(s): Stress elicits physiological and neuroendocrine responses mediated by the hypothalamic-pituitary-adrenal (HPA) axis and lateral hypothalamus (LH). However, prolonged stress can dysregulate neuropeptide systems like orexin.

Narcolepsy and rapid eye movement sleep

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Since the first description of narcolepsy at the end of the 19th Century, great progress has been made. The disease is nowadays distinguished as narcolepsy type 1 and type 2. In the 1960s, the discovery of rapid eye movement sleep at sleep onset led to improved understanding of core sleep‐related disease symptoms of the disease (excessive ...

Phenylketonuria [PDF]

open access: yes, 2004
Genome research is emerging as a new and important tool in biology used to obtain information on gene sequences, genomic interaction, and how genes work in concert to produce the final syndrome or phenotype. Defect in phenylalanine hydroxylase (PAH) gene

Acute optogenetic silencing of orexin/hypocretin neurons induces slow wave sleep in mice [PDF]

open access: yes, 2011
Orexin/hypocretin neurons have a crucial role in the regulation of sleep and wakefulness. To help determine how these neurons promote wakefulness, we generated transgenic mice in which orexin neurons expressed halorhodopsin (orexin/Halo mice), an orange ...

Ageing‐related modification of sleep and breathing in orexin‐knockout narcoleptic mice

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Narcolepsy type‐1 (NT1) is a lifelong sleep disease, characterised by impairment of the orexinergic system, with a typical onset during adolescence and young adulthood. Since the wake–sleep cycle physiologically changes with ageing, this study aims to compare sleep patterns between orexin‐knockout (KO) and wild type (WT) control mice at ...

Parasomnias and sleep‐related movement disorders induced by drugs in the adult population: a review about iatrogenic medication effects

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Parasomnias and sleep‐related movement disorders (SRMD) are major causes of sleep disorders and may be drug induced. The objective of this study was to conduct a systematic review of the literature to examine the association between drug use and the occurrence of parasomnias and SRMD.

Influence of sleep on seizures and interictal epileptiform discharges in epilepsy [PDF]

open access: yesEncephalitis
Sleep significantly influences seizure occurrence and interictal epileptiform discharges (IEDs) in patients with epilepsy. Sleep-related epilepsy, where seizures occur exclusively or predominantly during sleep, has been observed in various epilepsy ...

ATP-Sensitive Potassium Channel-Mediated Lactate Effect on Orexin Neurons: Implications for Brain Energetics during Arousal [PDF]

open access: yes, 2010
Active neurons have a high demand for energy substrate, which is thought to be mainly supplied as lactate by astrocytes. Heavy lactate dependence of neuronal activity suggests that there may be a mechanism that detects and controls lactate levels and/or ...
