Combined state-based kinematic decoding. A: comparison of actual kinematics (blue) for a single DoF, wristFE, with predicted kinematics from a kinematic decoder using spike recordings (green) or a state-based kinematic decoder using LFP amplitude for state decoding and spikes for kinematic decoding (red). Results are shown for a sample trial from session X0918. B: average CC and RMSE for prediction of arm, hand, and finger kinematics from 300 ms prior to Cue to FH, from 1) only a spike-based kinematic decoder (blue); 2) a spike-based state decoder combined with a spike-based kinematic decoder (green); and 3) an LFP-based state decoder combined with a spike-based kinematic decoder (orange). Decoding results averaged across all 18 joint angle and 3 end point DoFs as a function of different numbers of randomly selected spike recordings for the kinematic decoder (x-axis). Error bars indicate SE.
