Intrafascicular stimulation of monkey arm nerves evokes coordinated grasp and sensory responses

Supplemental Videos

3 video files in MPG format.

Files in this Data Supplement:

  • Video 1 - USEA Stimulation of the median nerve at the elbow causes finger and wrist movements. Finger and hand movements in responses to single-channel pulse-train stimulation are shown for six different electrodes. Movements are preceded by a title that indicates the digits or joints in motion during the following clip plus the individual electrode designation. All movements are shown twice in succession. Movements were often selective for certain fingers or joints.
  • Video 2 - USEA Stimulation of 3 arm nerves at the elbow to generate a power grip. A four second grip and release sequence is shown. This grip and release sequence used 6 electrodes, across all three implanted arm nerves, as indicated in Figure 5. The hand opens, accepts a 50g ball from the experimenter, holds it briefly, and then pronates and releases the ball. Supplemental Material (audio, video, data sets, program codes only) - USEA Stimulation of 3 arm nerves at the elbow to generate a precision grip.
  • Video 3 - USEA Stimulation of 3 arm nerves at the elbow to generate a precision grip. The hand a rest holds a piece of foam rubber. Upon stimulation, the foam rubber is compressed strongly by the index finger and thumb.
