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.

Orexin, released from the hypothalamus, has been implicated in various basic non-somatic functions including feeding, the sleep-wakefulness cycle, emotion, and cognition. However, the role of orexin i...
It is widely recognized that emotions impact an individual's ability to perform in a given task. However, little is known about how emotion impacts the various aspects of cognitive -motor performance....
A sport-related concussion (SRC) is a heterogeneous injury that requires a multifaceted and comprehensive approach for diagnosis and management, including symptom reports, vestibular/ocular motor asse...
The cerebellum regulates several motor functions through two main mechanisms, the cerebellum-brain inhibition (CBI) and the motor surround inhibition (MSI). Although the exact cerebellar structures an...
The present study aimed to contribute to the discussion about the relation between motor coordination and executive functions in preschool children. Specifically, the relation between gross and fine m...
The aim is to assess the effects of virtual reality-based intervention on vestibular functions in healthy community dwellers.
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...
Surgical removal of vestibular schwannoma causes acute vestibular symptoms, including postoperative vertigo and oscilopsia due to nystagmus. In general, the dominant symptom postoperativel...
G-protein-coupled NEUROPEPTIDE RECEPTORS that have specificity for OREXINS and play a role in appetite control, and sleep-wake cycles. Two principle receptor types exist, each having a specificity for OREXIN A and OREXIN B peptide subtypes.
Substances that bind to and inhibit the action of OREXIN RECEPTORS. Drugs in this class have been used as SLEEP AIDS.
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.
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.
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.

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...
