Surprise index from the narrow and wide spikes in NCM at 1 s ISI. For units with a wide spike waveform, SI in the control condition was not different from the alternating condition (U = 827.5, p = 0.255, n1 = 43, n2 = 42; Mann–Whitney U test). In contrast, for units with a narrow spike waveform, SI in the alternating condition was significantly larger than in the control condition (U = 49, p = 0.002, n1 = 24, n2 = 11; Mann–Whitney U test).
