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 Bullet Vibrators 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 freque
