Demonstration of the detection stability based on stability of local field potentials (LFPs) for both participants T2 and T6. Top: normalized mutual information (CYX) calculated by calibrating a decoder on all open-loop calibration blocks from one session and validating it on all open-loop calibration blocks of another sessions. The same amount of data was used to calibrate and validate each decoder. Bottom: same CYX values as a function of the decoder age ΔT (time between the session used to calibrate the decoder and the session used to validate it). Black lines show the linear ordinary least squares fit to the CYX values. P value of testing for significant correlation between ΔT and CYX is given.
