Effects of rise-time of stimulus on auditory N1m to air-conducted, bone-conducted audible and bone-conducted ultrasonic sounds

چکیده
condition elicited smaller N1m amplitude than the incongruent condition. In both hemispheres, the stepwise multiple regression revealed that the reduction rate of N1m amplitudes between the presented conditions correlated significantly with the source activities in motor and superior temporal areas. The present study suggested that some sensorimotor mediated prediction modulated auditory activity when one observed the other vocalizing. And the correlation between the change rate of N1m amplitudes and the visual evoked responses suggests that the activation of motor areas mediates predictive perception of vowel sounds.

Dynamic range for bone conduction ultrasound
Since Gavreau [1] reported that ultrasound could be perceived by bone conduction, controversial discussions have surrounded the concept of the auditory perception of ultrasound. Particular attention has been paid to its perception mechanism and to whether or not the profoundly hearingimpaired can detect ultrasound and discriminate ultrasound modulated by different speech sounds. Consideration i...
متن کاملLateralization of Amplitude-modulated Bone-conducted Ultrasounds: Discrimination of Interaural Time and Intensity Differences and Time-intensity Trading
Ultrasonic vibration generates the sensation of sound via bone-conduction; the phenomenon is called bone-conducted ultrasonic hearing. Complex sounds also can be perceived by amplitude-modulated bone-conducted ultrasound (AM-BCU). In this study, three experiments were conducted to examine whether interaural time differences in the amplitude envelopes (envelope-ITDs) and interaural intensity dif...
متن کاملVestibular Evoked Myogenic Potential Produced by Bone-Conducted Stimuli: A Study on its Basics and Clinical Applications in Patients With Conductive and Sensorineural Hearing Loss and a Group With Vestibular Schawannoma
Introduction: Vestibular evoked myogenic potential (VEMP) has recently been broadly studied in vestibular disorders. As it is evoked by loud sound stimulation, even mild conductive hearing loss may affect VEMP results. Bone-conducted (BC) stimulus is an alternative stimulation for evoking this response. This study aims to assess the characteristics of BC-VEMP in different groups of patients. ...
متن کاملUltrasound activates the auditory cortex of profoundly deaf subjects.
Using three-dimensional PET, the cortical areas activated by bone-conducted ultrasound were measured from five profoundly deaf subjects and compared with the cortical areas of normal-hearing subjects activated by stimuli through bone-conducted ultrasonic, air-conducted, bone-conducted, and vibro-tactile hearing aids. All of the hearing aids, including the ultrasonic hearing aid, consistently ac...
متن کاملVestibular activation by bone conducted sound.
OBJECTIVE To examine the properties and potential clinical uses of myogenic potentials to bone conducted sound. METHODS Myogenic potentials were recorded from normal volunteers, using bone conducted tone bursts of 7 ms duration and 250-2000 Hz frequencies delivered over the mastoid processes by a B 71 clinical bone vibrator. Biphasic positive-negative (p1n1) responses were recorded from both ...
