Distribution of preferred grip type and orientation in different cell classes. A, Ratio of precision and power preference in cell groups with early (top row), intermediate (middle), and late (bottom) tuning onset for grip type. In all three task epochs, early-tuned cells preferred power grips and precision grips approximately equally often. In contrast, ∼70% of late tuning cells preferred precision grips. B, Number of cells with a particular orientation preference for the three cell classes. In early orientation-tuned cells, the portion of cells that preferred extreme orientations (±50°) changed little from cue (49%) to movement (53%), while 78% of cells with a late onset of orientation tuning preferred extreme orientations.
