Objectives: Apert syndrome affects the craniofacial structures resulting in craniosynostosis, craniofacial anomalies and syndactyly. Although many characteristic features are recognized, vestibular dysfunction is a little known feature that can often be present. This can cause a delay in the attainment of gross motor milestones and impair motor function. We aimed to examine this cohort to revie...

In everyday life, vestibular receptors are activated by both self-generated and externally applied head movements. Traditionally, it has been assumed that the vestibular system reliably encodes head-in-space motion throughout our daily activities and that subsequent processing by upstream cerebellar and cortical pathways is required to transform this information into the reference frames requir...

HYPOTHESIS Anatomic differences may render the superior division of the vestibular nerve more susceptible to injury during vestibular neuritis. BACKGROUND Neural degeneration has been identified in temporal bone studies of vestibular neuritis. Previous anatomic and physiologic studies of vestibular neuritis have demonstrated that the superior division of the vestibular nerve is preferentially...

The vestibular system provides the brain with sensory signals about three-dimensional head rotations and translations. These signals are important for postural and oculomotor control, as well as for spatial and bodily perception and cognition, and they are subtended by pathways running from the vestibular nuclei to the thalamus, cerebellum and the "vestibular cortex." The present review summari...

Rats use rhythmic movements of their vibrissae (whiskers) to tactually explore their environment. This "whisking" behavior has generally been reported to be strictly synchronous and symmetric about the snout, and it is thought to be controlled by a brainstem central pattern generator. Because the vibrissae can move independently of the head, however, maintaining a stable perception of the world...

background: multiple sclerosis (ms) is a chronic neurological disease that affects brain and spinal cord. the infratentorial region contains the cerebellum and brainstem. vestibular evoked myogenic potentials (vemps) are short-latency myogenic responses. cervical vestibular evoked myogenic potential (cvemp) is a manifestation of vestibulocolic reflex and ocular vestibular evoked myogenic potent...

BACKGROUND Recent studies have extended our understanding of the pathophysiology, natural course, and treatment of vestibular vertigo. The relative frequency of the different forms is as follows: benign paroxysmal positional vertigo (BPPV) 17.1%; phobic vestibular vertigo 15%; central vestibular syndromes 12.3%; vestibular migraine 11.4%; Menière's disease 10.1%; vestibular neuritis 8.3%; bilat...

OBJECTIVE Dizziness associated with vestibular schwannoma is usually ascribed to retrolabyrinthine mechanisms. The goal of this study was to determine if quantitative peripheral vestibular (labyrinthine) otopathology was present in a series of patients with vestibular schwannoma. STUDY DESIGN Comparative human temporal bone study. SETTING Otopathology laboratory. SUBJECTS AND METHODS Temp...
