An example of PSTHs of target triplet responses for different time shifts (rows) and in different semitone conditions (columns) observed from a single multiunit recording site. The vertical axis corresponds to the rate of the number of spikes per second. Dashed lines indicate the onset of each tone of the standard ABA- triplet without a time shift. The PSTHs were constructed from 60 responses for sham trials (0% shift) and 20 responses for targets (10–90% shift). The recording site was tuned to 1.9 kHz, and A and B tone frequencies were set accordingly [at the CF if Δf was 0 semitones and equally distant from the CF (in semitones) if Δf was 6 or 12 semitones].
