Figure 8: Changes in power spectrum in the low frequencies (1–8Hz).

Figure 8:

See label of Figure 7 for details of the power spectrum was computed. On each box, the central mark indicates the median power value, and the bottom and top edges of the box indicate the 25th and 75th percentiles, respectively. Individual epoch-wise power values are plotted using the ‘+’ symbol. There was progressive increase in power in the lower frequencies, especially in 1Hz (Welch’s ANOVA: F(5,528.53) = 159.50, p < 0.001), 2Hz (one way ANOVA: F(5,1134) = 54.51, p < 0.001), 3Hz (one way ANOVA: F(5,1134) = 70.73, p < 0.001) and 4Hz (one way ANOVA: F(5,1134) = 67.0415, p < 0.001). Asterisks in superscript of the nth level indicate significant change of the value from the previous level. (Games-Howell/Tukey’s post hoc test, ** p < 0.001, * p < 0.05).
