Raster plots and histograms of typical examples of three types of activity in DN cells with RFs in the distal part of the arm. Neuron activity recorded in the pronated posture is illustrated. DN cells were classified into three types based on movement-related modulations between −200 to +200 ms relative to movement onset. This figure uses the same conventions as Figure 4. A: Activity of type 1 DN cells showed suppression before movement onset. B: Activity of type 2 DN cells showed suppression before movement onset for some directions and facilitation for other directions. C: Activity of type 3 DN cells showed facilitation before movement onset. Note that the scale bars for discharge rate shown in the top row of panels differ for the three cells.
