background: ménière’s disease  has been  remained  as a difficult therapeutic  challenge. the  present  study aimed to   determine    the effects of  one-shot low-dosage intratympanic   gentamicin   on  vertigo control, auditory outcomes  and  findings of computerized  dynamic posturography  and   vestibular  evoked  myogenic potentials in patients with unilateral ménière’s disease. methods: in...

The goals of this study were (i) to assess the replicability of the "perceptual magnet effect" [Iverson and Kuhl, J. Acoust. Soc. Am. 97(1), 553-561 (1995)] and (ii) to investigate neurophysiologic processes underlying the perceptual magnet effect by using the mismatch negativity (MMN) auditory evoked potential. A stimulus continuum from /i/ to /e/ was synthesized by varying F1 and F2 in equal ...

Conventional techniques for the noninvasive measurement of brain activity involve critical limitations in spatial or temporal resolution. Here, we propose the method for noninvasive brain function measurement with high spatiotemporal resolution using optical signals. We verified that diffused near-infrared light penetrating through the upper jaw and into the skull, which we term as optoencephal...

purpose: to evaluate the effect of vertical prism induced stress on binocular visual evoked potentials. methods: using checkerboard stimulus patterns in two spatial frequencies (sfs) of 0.48 cpd as a low sf and 2.18 cpd as a moderate sf reversing with temporal frequency of 4 hz, the effect of increasing visual stress using vertical prisms of 0, 1, 2 and 3 prism diopters on binocular visual evok...
