Supplementary Notes

This file contains Supplementary Figures 1 and 2 and legends, Supplementary Methods and Results, Supplementary Discussion, Supplementary Video Legends and Supplementary References. The two figures illustrate neuronal selectivity for imagined and performed movements, and center-out task performance with an alternate post-hoc control. Also reported is additional information regarding signal quality and variety; MI activity during neural cursor control; center-out task; grid task; summary of neurophysiologic findings; comparison with previous work; video legends.

Supplementary Video 1

Center-Out task.

Supplementary Video 2

Video showing use of a computer interface with the neural cursor.

Supplementary Video 3

Neurally-controlled television.

Supplementary Video 4

Neural "Pong".

Supplementary Video 5

Neural "HeMan" game.

Supplementary Video 6

Direct neural control of a prosthetic hand. MN was initially instructed to move a neural cursor "up" to open the hand, and "down" to close the hand.

Supplementary Video 7

Transport of an object from one location to another via direct neural control of a multi-articulated robot arm.

Supplementary Video 8

Trial Participant #2 performing Center-Out task.
