  1. (Upper table) Hurst exponent for the entire time series (hpeak) and widths of multifractal spectrum (distance of local Hurst exponent at − 10 < q < 10) obtained from individual animals in the indicated activity class or mutant animals in high-motility and low-motility time regimes. (Shorter table) p-values from t tests of differences in hpeak and width from upper table in indicated comparisons; *p < 0.05.
