Supplementary Notes
This file contains Supplementary Video Legends, Supplementary Discussion, Supplementary Methods, Supplementary Figures 1–7 and Supplementary Table 1. The Supplementary Discussion covers the following topics: motor-related activity in the absence of the visual stimulus, selection of Tskip, ITRC for multi-target task, ITRC comparisons with monkey G, effects of losing neural units on single-trial accuracy, and EMG measurements.
Supplementary Video 1
Instructed-delay task. This video shows the monkey's performance in the instructed-delay task. Trials were started by touching the center square and fixating the cross. The reach target appeared in the periphery and the monkey was required to wait until the 'go' cue before making the reach.
Supplementary Video 2
Moderately-paced BCI experiments. This video shows the monkey's performance during a moderately-paced BCI experiment. Video annotations are used to denote real reaches and prosthetic cursor trials (not seen by monkey).
Supplementary Video 3
Fast-paced BCI experiments. This video shows the monkey's performance during a fast-paced BCI experiment. The video contains three separate sequences, each of five cursor trials followed by a real reach. The three sequences were performed at different times in the experiment.
