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. Participants performed a vestibular discrimination task on a motion platform while viewing emotional pictures. Six different picture categories were taken from the International Affective Picture System:...

CONCLUSIONS The patients who received electric acoustic stimulation (EAS) cochlear implantation had relatively good vestibular function compared with the patients who did not have residual hearing. The vestibular function was well preserved after atraumatic EAS surgery. The round window approach and soft electrode are preferred to decrease the risk of impairing vestibular function. OBJECTIVES...

Vestibular neuritis is the most common cause of acute spontaneous vertigo. Vestibular neuritis is ascribed to acute unilateral loss of vestibular function, probably due to reactivation of herpes simplex virus in the vestibular ganglia. The diagnostic hallmarks of vestibular neuritis are spontaneous horizontal-torsional nystagmus beating away from the lesion side, abnormal head impulse test for ...

  Background :Aging can cause loss of balance, which may lead to physical and psychological problems. As the role of the otolith organs in maintaining postural stability has been emphasized in recent years, the present study investigated the effect of aging on saccular function using cervical vestibular evoked myogenic potentials (cVEMP).   Methods : The participants were assigned into two grou...

INTRODUCTION The loss of vestibular function cannot be restored in all cases, but a vestibular prosthesis can improve balance in many of these patients. Vestibular implant (VI) research has mostly focused on the detection of angular velocity of the cephalic movements through gyroscopes and stimulation of the three-ampulla crests of the semicircular canals in order to improve the vestibular ocul...

Dynamic motion simulators cannot provide the same stimulation of sensory systems as real motion. Hence, only a subset human senses should be targeted. For providing vestibular stimulus, an automatic bodily function vestibular–ocular reflex (VOR) can objectively measure how accurate simulation is. This requires model ocular response to enforced accelerations, attempt create which is shown in thi...

Sensory input evokes low-order reflexes and higher-order perceptual responses. Vestibular stimulation elicits vestibular-ocular reflex (VOR) and self-motion perception (e.g., vertigo) whose response durations are normally equal. Adaptation to repeated whole-body rotations, for example, ballet training, is known to reduce vestibular responses. We investigated the neuroanatomical correlates of ve...

Cerebellar Purkinje cells have two distinct action potentials: complex spikes (CSs) are evoked by single climbing fibers that originate from the contralateral inferior olive. Simple spikes (SSs) are often ascribed to mossy fiber-granule cell-parallel fiber inputs to Purkinje cells. Although generally accepted, this view lacks experimental support. Vestibular stimulation independently activates ...
