Temporal features of LA segments. A Global distribution of LA segments between vigilance states across study with examples of MUA amplitude during LA segments displayed for each state. Each figure shows 400 randomly selected LA segments sorted by duration. Segment time range = onset -100 ms to onset + 300 ms. Colour of each segment scaled to MUA amplitude (dark = low, colour = high). B The effect of vigilance state on the incidence of LA segments. Incidence values reported as number per minute of vigilance state. C The effect of vigilance state on the proportion of 4-s epochs containing an LA segment. D Frequency of LA segments as a function of duration for each vigilance state. Inset y-axis scaled to increase resolution of REM and WAKE states. E The effect of vigilance state on the duration of LA segments. Black/grey = NREM, green = REM, blue = WAKE. N = 7. Mean ± SEM. Significance of effects assessed using one-way repeated measures ANOVA followed by post-hoc pairwise t-tests with Bonferroni correction (*P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001)
