Heatmaps of percent determinism (det) and percent recurrence (rec) from cross-recurrence quantification for electroencephalogram (EEG) and center of mass (COM) data from each subject (rows). EEG data include alpha, beta, gamma, and combined theta/delta (SCO) bands averaged across three intrahemispheric channels. COM data include anteroposterior (AP), mediolateral (ML), vertical (VT), and resultant (RES) accelerations. {m = 3, r = 0.2, τ = 16, tw = 1}. Data were scaled relative to the highest value observed across these subjects; darker shades represent higher determinism and recurrence, respectively.
