Modeling ECoG features as an underlying dynamical system using LFADS uncovers repeatable trajectories through a low-dimensional state space during the kinematic-kinetic task. Shown are LFADS-PCs (labeled as PC for simplicity) derived from high-frequency (A, B) and low-frequency (C, D) ECoG features. Single-trial trajectories are shown for subjects S5 (78 trials; A, C) and S6 (73 trials; B, D). Inset boxes in each panel show the trajectories resulting from PCA performed directly on the ECoG features (without LFADS). The color code at bottom defines the portion of each trial corresponding to each behavioral mode.
