Amplitude of ChOx activity and O2 transients as a function of SWR count in a 2 s time window, sorted by different percentile ranges of summed ripple power. The data was collected from three recording sessions. Statistic tests were performed by two-way ANOVA for unbalanced data following ART to account for non-gaussian distributions. In recording session 1, both SWR count and total ripple power significantly affected the amplitude of ChOx and O2 (p<0.0001 for count and F2,762 = 10.2 for count, p<0.001 and F2,762 = 8.24 for power in COA data; p<0.001 and F2,762 = 9.98 for count, p=0.004 and F2,762 for power in O2 data). The same applied for recording 2 (p<0.0001 and F2,803 = 14.35 for count, p<0.0001 and F2,803 = 12.3 for power in COA data; p<0.0001 and F2,803 = 16.9 for count, p<0.0001 and F2,803 = 12.1 for power in O2 data). As for recording session 3, the SWR count effect was significant for both sensor signals (p<0.0001 and F2,618 = 11.3 for COA; p=0.032 and F2,618 = 3.47 for O2) and the summed ripple power significantly affected O2 (p=0.016 and F2,618 = 4.14), but was not consistently related to ChOx transients amplitude (p=0.07, F2,618=2.71).
