“…Along the way oculomotor-related oVEMPs, certain vestibulo-spinal reflexes like cVEMP and also the stapedius reflex to loud acoustic stimuli are activated and contribute to temporally overlapping potentials, on which there is extensive literature and reviews elsewhere (Leibner et al, 1990;Li et al, 1993Li et al, , 1995O'Beirne and Patuzzi, 1999;Rodionov et al, 1996;Sichel et al, 2000;Miyamoto et al, 2007;Rosengren et al, 2005Rosengren et al, , 2009aRosengren et al, ,b, 2010aRosengren et al, ,b, 2011. The present study was focused on later potentials of the multisensory and interconnected cortical patches of the ''vestibular network'', including anterior insular and posterior opercular regions.…”

“…Ascending cortical potentials associated with acoustic vestibular stimulation have been investigated by distributed source LoRETA (low resolution electromagnetic tomography analysis, McNerney et al, 2011) and basic discrete source analysis (Todd et al, 2003(Todd et al, , 2007(Todd et al, , 2008McNerney et al, 2011), all focused on potentials prior to 20-30 ms. At present, these early potentials are discussed to be related to intraorbital presaccadic activity, different from motions of the eye dipole by certain authors. They are either referred to as ''oculomotor oVEMP'' (Todd et al, 2007(Todd et al, , 2008Sandhu and Bell, 2009;Rosengren et al, 2005Rosengren et al, , 2009aRosengren et al, ,b, 2010aRosengren et al, ,b, 2011 or ''medium-latency vestibular evoked potentials ML-VsEP'' (Leibner et al, 1990;Rodionov et al, 1996;Miyamoto et al, 2007). Some authors relate potentials <20 ms after a specific vestibular stimulus already to vestibular cortical activity (DeWaele et al, 2001;McNerney et al, 2011).…”

“…In recent years, a new method for induction and recording of short‐latency vestibular evoked potentials (VsEPs) in response to angular 10–12 and linear 13,14 acceleration has been developed in both laboratory animals 10–14 and human subjects. 15,16 It has been shown that the first peak of the VsEPs is the compound action potential of the vestibular nerve fibers synchronously activated by the stimulus 17 and therefore reliably reflects the function of the vestibular end‐organ. 18 Thus VsEP recordings are an objective method for directly evaluating vestibular end‐organ function, as opposed to other, less direct methods, such as the vestibular ocular reflex, which have been used previously.…”

Objectives/Hypothesis: To evaluate and compare the effect of chlorhexidine gluconate, povidoneiodine, and alcohol-three antiseptics used before ear surgery-on the function of the vestibular and cochlear parts of the sand rat's inner ear. The assessment of damage is based on the recording of vestibular evoked potentials (VsEPs) and auditory brainstem response (ABR). Study Design: Prospective controlled animal study. Methods: Fat sand rats were randomly assigned to five different groups, each receiving topical application of a different agent: saline (control), gentamicin (ototoxic control), chlorhexidine, povidone-iodine, and alcohol. Right-side total labyrinthectomy was performed, and a polyethylene tube was inserted into the left (contralateral) middle ear. After baseline recordings were taken of VsEPs and ABR, each animal received five consecutive daily applications of the specific agent into the left middle ear. Three days after the fifth application, evoked potential recordings (VsEPs and ABRs) were repeated and compared with baseline measurements. Results: Administration of saline affected neither VsEPs nor ABR. In contrast, as expected, neither of these responses could be recorded after gentamicin application. After application of chlorhexidine all waves disappeared in all sand rats. Alcohol caused the waves to disappear in some of the animals only. Povidone-iodine did not affect VsEP recordings and had only a small effect on ABR. Conclusions: Chlorhexidine and alcohol had a clear toxic effect on the vestibular and cochlear function of the inner ear of the sand rat, whereas povidone-iodine did not. Thus, taking into consideration that this is an animal study, it appears that povidone-iodine might be preferable to the other agents tested in disinfecting ears with a perforated tympanic membrane.

“…The amplitudes of the wave decrease and their latencies increase as stimulus intensity decrease. The human VsEPs showed consistency over time (weeks to months of follow-up) and intersubject similarity [69][70][71]. The acceleration impulses in the plane of the horizontal SCCs activate one lateral SCC (excitation) whereas the contralateral canal is inhibited.…”

“…This method was used for investigation in experimental animals [25,26,[64][65][66][67][68] and later was implemented in human beings [69][70][71][72][73][74]. It is based on the presentation of short and intense acceleration impulses with rise time of 1-3 ms which are transmitted to the head by special devices.…”

Recently it was shown that abrupt head acceleration impulses induce short latency response in the neuronal pathways of the vestibular system and a short latency vestibulooculomotor response. This phenomenon cannot be explained only with the frame of the classical torsion pendulum model of the cupuloendolymphatic system and passive reaction of the vestibular receptors to the cupular displacement. All three stages of stimulus transduction: mechanical, receptive and neuronal, are revisited in recent studies, and these findings are analyzed in the present paper. The head impulse test of Halmagyi and his colleagues, the high frequency head oscillations using special helmet [Tabak et al., 1995, 1997a, b], the autorotation test [O’Leary, 1990; Hirvonen 1998], the technique of recording vestibular evoked potentials to acceleration impulses [Elidan at al.] are discussed. In spite of some deficits in our knowledge, the exclusive diagnostic value of the high-frequency and high-intensity (impulse) stimuli became already obvious. It is concluded that the proper differentiation between the mechanical, receptor and afferent neuronal parts of the vestibular end organ may be achieved only by applying stimuli with different frequency content. Further investigations are requested to elucidate the specific mechanisms of vestibular sensitivity to the different stimuli used for this purpose, and the possible directions of these studies are discussed.
