An acquisition method for the MLR of auditory evoked potentials

The study is focused on the recording of the auditory evoked potential to stimuli that result in binaural (two-ear) interaction. The auditory evoked potential is derived from small bioelectric potentials recorded from the scalp. The AEP is categorized on the basis of the latency of the response following the auditory stimulus. For example, the auditory brainstem response (ABR) occurs in the first 20 ms after the stimulus, the middle latency response (MLR) from 20 to 70 ms, and the slow vertex response (SVR) up to 500 ms after stimulation. The study of auditory evoked potentials may provide insight in the mechanism of auditory processing in the brain. The study presents a methodology to measure AEP related to binaural hearing.
