Percentage variance accounted for by spatial modes associated with the dynamics of MIB. The first spatial modes from the second analysis stage (Fig. 3) were used to determine percentage variance accounted for in different subsets of MIB runs. A, Percentage variance accounted for by first spatial mode for high- versus low-rate MIB (Fig. 3A). B, Percentage variance accounted for by first spatial mode for long- versus short-duration MIB (Fig. 3B). Error bars indicate SEM; *p < 0.05; **p < 0.01; ***p < 0.001, two-sided permutation tests).
