The vestibular nuclear complex (VNC) consists of a collection of sensory relay nuclei that integrates and relays information essential for coordination of eye movements, balance, and posture. Spanning the majority of the hindbrain alar plate, the rhombomere (r) origin and projection pattern of the VNC have been characterized in descriptive works using neuroanatomical tracing. However, neither t...

BACKGROUND Rheumatoid arthritis (RA) is an autoimmune systemic disease. Most common autoimmune diseases are multisystem disorders that may also present with otological manifestations, and autoimmune inner ear disease accompanied by vestibular dysfunction. This study aimed to compare the vestibular function between RA patients and normal subjects using cervical vestibular evoked myogenic potenti...

Cerebellar control of movements is dependent on mossy fiber input conveying information about sensory and premotor activity in the spinal cord. While much is known about spino-cerebellar systems, which provide the cerebellum with detailed sensory information, much less is known about systems conveying motor information. Individual motoneurones do not have projections to spino-cerebellar neurons...

INTRODUCTION Vertigo is one of the most unpleasant symptoms. Two of the main points of the examinations are the vestibulospinal tests (Romberg test and Unterberger- Fukuda test) can be measured objectively by the ultrasound-computer-craniocorpography. OBJECTIVES Using ultrasound-markers on head and shoulders, the ultrasound-computer-craniocorpography can measure and analyze the numerical data...

Aberrant vestibular nuclear function is proposed to be a principle driver of limb muscle spasticity after stroke. We sought to determine whether altered cortical modulation of descending vestibulospinal pathways post-stroke could impact the excitability of biceps brachii motoneurons. Twelve chronic hemispheric stroke survivors aged 46-68 years were enrolled. Sound evoked biceps myogenic potenti...

The responses of vestibulospinal neurons to 0.5-Hz, whole-body rotations in three-dimensional space and static tilts of whole-body position were studied in decerebrate and alert cats. The neurons' spatial properties for earth-vertical rotations were characterized by maximum and minimum sensitivity vectors (R(max) and R(min)) in the cat's horizontal plane. The orientation of a neuron's R(max) wa...

The behavioral effects of ethanol have been studied in multiple animal models including zebrafish. Locomotion of zebrafish larvae is resistant to high concentrations of ethanol in bath solution. This resistance has been attributed to a lower systemic concentration of ethanol in zebrafish when compared with bath solution, although the mechanism to maintain such a steep gradient is unclear. Here ...

OBJECTIVE We investigated the potential of galvanic vestibular stimulation (GVS) to quantify lateralised asymmetry of the vestibulospinal pathways by measuring balance responses to monaural GVS in 10 subjects with vestibular schwannoma and 22 healthy control subjects. METHODS Subjects standing without vision were stimulated with 3 s, 1 mA direct current stimuli delivered monaurally. The mean ...

mainder is concerned with the vestibular system. This book will be of greatest value to clinical and laboratory investigators studying postural control or vestibular function. The twenty-six members of the symposium are prominent investigators from such fields as neuroanatomy, neurophysiology, and otolaryngology. The material is based upon published results which appeared up to late 1967. There...

Many authors have reported different useful studies in evaluating vestibular function through vestibular, somatosensory, and visuocortical systems using the test of balance and in assessing vestibular function through the vestibulospinal system using craniocorpography. We researched 100 patients suffering from tinnitus and vertigo (36 men and 64 women). Diagnoses of vestibular dysfunction can b...
