AMLRs are those replicable positive and negative peaks that occur between 10 and 50 ms, after the onset of the eliciting signals (Goldstein). Waveform characteristics of AMLR: It is usually consists of 3 positive and 3 negative peaks, which are labelled as No, Po, Na,Pa, Nb, Pb (Goldstein & Redman, 1967). AMLR is consist of biphasic waveform with a negative wave occurring at about 20 ms (Na), a positive wave occurring at about 30 msec (Pa), a second negative ...
