Offline Wiener filter predictions of cursor and target locations. (A–D) A 25 s epoch of trials during a session with monkey M. (A) Cursor X and Y positions (black) and corresponding Wiener predictions (red) during selected epoch. (B) The radial distance of the predicted cursor location was computed and plotted versus time. Reach threshold level of 5 cm is shown as horizontal gray line. (C) True target X and Y position during selected epoch (black) and Wiener predictions (red). (D,E) Probability distribution of the time of true target onset relative to threshold crossings from monkey M (D) and monkey N (E). Inset: fraction correct predictions of cursor and true target location during the 0 to 0.8 s epoch beginning with threshold crossing.
