The ability of the vestibulo-ocular reflex (VOR) to alter the phase of the motor output relative to the sensory input is examined. Alert cats were trained for 2 h with 0.25 Hz sinusoidal horizontal vestibular and vertical optokinetic rotational stimuli. In each experiment the optokinetic training stimulus was phase shifted by 0 degree, +45 degrees, -45 degrees, or 90 degrees from the vestibular...

Brain-derived neurotrophic factor (BDNF) is known to be crucial for the development of peripheral vestibular neurons. However, the maturation profile of the BDNF signal transducing receptor, tyrosine kinase B (TrkB) in functionally activated otolith-related vestibular nuclear neurons of postnatal rats remains unexplored. In the present study, conscious Sprague-Dawley rats (P4 to adult) were sub...

This study was performed following favorable results from a previous research, which studied the response of acute vestibular patients to the rotatory maneuver, to investigate the effects of the rotatory maneuver on chronic vestibular patients. In an attempt to normalize the patient’s directional preponderance (DP), and hence their vestibular symptoms, the study was designed to reduce the imbal...

migraine is a neurologic disease, which often is associated with a unilateral headache. vestibular abnormalities are common in migraine. vestibular evoked myogenic potentials (vemps) assess otolith function in particular functional integrity of the saccule and the inferior vestibular nerve. we used vemp to evaluate if the migraine headache can affect vemp asymmetry parameters. a total of 25 pat...

Adaptation or resistance of fish Mauthner cells (M-cells) to long duration (2 h) vestibular stimulation (LDS) was produced by daily brief and gradually increasing vestibular stimulation (training). The LDS resistance was accompanied by an increase in the number of desmosome-like junctions in the afferent axosomatic synapses. F-actin, the main component of desmosome-like contacts, has been sugge...

Children with hearing impairment have deficits of balance and motors. Although most of parents teach deaf children communication skills in early life, but rarely teach the deficits of balance. The purpose of this study was to investigate whether static balance improved after table tennis training. Table tennis training was provided four times a week for eight weeks to two 12-year-old deaf child...
