Effects of Contralateral Noise on the 20-Hz Auditory Steady State Response - Magnetoencephalography Study

Effects of Contralateral Noise on the 20-Hz Auditory Steady State Response - Magnetoencephalography Study

The auditory steady state response (ASSR) is an oscillatory brain response, which is phase locked to the rhythm of an auditory stimulus. ASSRs have been recorded in response to a wide frequency range of modulation and/or repetition, but the physiological features of the ASSRs are somewhat different depending on the modulation frequency. Recently, the 20-Hz ASSR has been emphasized in clinical e...

The effects of propofol on the 40-Hz auditory steady-state response and on the electroencephalogram in humans.

The auditory steady-state response (ASSR) is a nearly sinusoidal electrical response of the brain to auditory stimuli delivered at fast rates. The amplitude of the response is largest for stimulus rates near 40/s, hence the label 40-Hz ASSR. We have studied the effects of propofol (1.5 mg/kg) on the 40-Hz ASSR in 14 patients. The spectral edge frequency (SEF) and median frequency (MDF) of the e...

Chapter Eight : The 80 - Hz Auditory Steady - State Response Compared with Other Auditory

Effects of interaural time and level differences on the binaural interaction component of the 80 Hz auditory steady-state response.

The auditory steady-state evoked response (ASSR) is a scalp-recorded potential elicited by modulated sounds or repetitive transient sounds presented at a high rate. The binaural interaction component (BIC) of the ASSR equals the difference between the response to binaural stimuli and the sum of the responses to a monaural stimulus presented to the left ear and the right ear. This study examined...

Effects of contralateral noise on the measurement of auditory threshold.

It is well known that sound presented in the contralateral ear can elicit the activity of the olivocochlear (OC) efferent. In the present study, the effects of the addition of contralateral noise on the psychophysical measurements of auditory thresholds were investigated in human subjects with normal hearing. The results obtained in the present study indicate that the addition of contralateral ...
