A study by Zhang et al. in this issue of Neuron reveals a novel mechanism of control of vestibular motor functions by the orexin (hypocretin) system in the perifornical/LH area through the lateral vestibular nucleus in the brainstem. This knowledge provides new insights into the understanding of brain circuitry that controls motor functions and diseases/conditions related to impairments in this circuitry.

In this issue, Nagase and colleagues report the discovery of the first selective nonpeptidic orexin 2 receptor (OX2R) agonists. The discovery of these OX2R selective agonists opens up new avenues for ...
Orexins are a family of neuropeptides that regulate sleep/wakefulness, acting on two G protein-coupled receptors, orexin receptors-1 (OX1R) and -2 (OX2R). Genetic and pharmacologic evidence suggests t...
Recent studies have shown that vestibular stimulation can influence affective processes. In the present study, we examined whether emotional information can also modulate vestibular perception. Partic...
Neuropeptides orexin A and orexin B, which are exclusively produced by neurons in the lateral hypothalamic area, play an important role in the regulation of a wide range of behaviors and homeostatic p...
Locus coeruleus (LC) nucleus is involved in noradrenergic descending pain modulation. LC receives dense orexinergic projections from the lateral hypothalamus. Orexin-A and -B are hypothalamic peptides...
The aim of this study is to assess if early supported vestibular rehabilitation can reduce dizziness and improve daily life activities in patients with acute vestibular injury. Our study ...
The purpose of this study is to determine whether vestibular disorders could affect visuo-spatial cognition. Visuo-spatial cognition will be evaluated using a new computerized test using a...
OBJECTIVES: I. Evaluate whether vestibular rehabilitation training is of value in reducing anxiety symptoms in patients with panic disorder with or without agoraphobia who have vestibula...
The bioelectrical responses of muscle, evoked by sound, obtained with a device considered the gold standard (widely used in clinics and hospitals) are similar to those obtained with a new ...
Neurological pathologies cause important and permanent disabilities in every day life. These pathologies can follow stoke, affecting two people per one thousand each year or cerebral palsy...
A condition characterized by inactivity, decreased responsiveness to stimuli, and a tendency to maintain an immobile posture. The limbs tend to remain in whatever position they are placed (waxy flexibility). Catalepsy may be associated with PSYCHOTIC DISORDERS (e.g., SCHIZOPHRENIA, CATATONIC), nervous system drug toxicity, and other conditions.
Photosensory rhodopsins found in microorganisms such as HALOBACTERIA. They convert light signals into biochemical information that regulates certain cellular functions such as flagellar motor activity.
The vestibular part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The vestibular nerve fibers arise from neurons of Scarpa's ganglion and project peripherally to vestibular hair cells and centrally to the VESTIBULAR NUCLEI of the BRAIN STEM. These fibers mediate the sense of balance and head position.
Vestibular nucleus lying immediately superior to the inferior vestibular nucleus and composed of large multipolar nerve cells. Its upper end becomes continuous with the superior vestibular nucleus. (From Dorland, 28th ed)
Pathological processes of the VESTIBULAR LABYRINTH which contains part of the balancing apparatus. Patients with vestibular diseases show instability and are at risk of frequent falls.

Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
