Figure 2. Example of the effects of contralateral noise on the waveform of the 40-Hz ASSR (Subject 3).

Figure 2

A: left-ear stimulation with AM signal, B: right-ear stimulation with AM signal. ASSR with contralateral noise (red) are superimposed on waveforms without contralateral noise (black), mapped onto a flattened projection of the sensor array. Asterisks in A and B indicate the channels of maximum signals in each hemisphere. The responses of the channels of the maximum signals (indicated with asterisks) are magnified and shown in the inserts in the right column (C, D).
