Figure 6.

Firing rate of a single unit during Reaching over one whole Monkey F session as a function of x-velocity. Because individual 30 ms data points (a) were noisy, the data were time binned at 300 ms intervals (b) and then velocity binned at 50 mm/s intervals along the abscissa (c) to show how well the actual data (green) followed the linear fit (magenta). Error bars indicate 2 SE. Bins with <10 points were excluded from plotting.
