Grand averaged source waveforms across all participants from Left and Right Hemispheres. (A) The two different degrees of frequency separation between A and B tones (Δf = 2 semitones [black lines] and Δf = 4 semitones [grey lines]) which were presented in the first experimental session are shown. The responses recorded from their presentation as Adaptation (on top) or Test (below) sequences are shown. (B) The second experimental session presented stimuli of Δf = 2 (black lines) and Δf = 10 semitones (grey lines), presented as Adaptation (top) and Test (below) sequences.
