Figure 5.
Total population of M1 units that had significantly higher FRs for rewarding (red), nonrewarding (blue) trials, or neither (gray) across manual (left column) and observational (right column) tasks for contralateral (A, C, D) and ipsilateral (B) M1 cortices (Wilcoxon signed-rank test, p < 0.05). Each column in the bar chart represents precue (500 ms), postcue (800 ms), prereward (500 ms), and postreward (500 ms) periods. A, B are for the center-out reaching tasks, and C, D are for the grip force tasks.
