Simulation results for the 2D reaching movements.

<p>(<b>A</b>) MDVs for the 8 muscle groups. SFi, inner shoulder flexor (blue); SFo, outer shoulder flexor (light blue); SEi, inner shoulder extensor (orange); SEo, outer shoulder extensor (yellow); EF, elbow flexor (green); EE, elbow extensor (magenta); BiF, biarticular flexor (cyan); and BiE, biarticular extensor (red). (<b>B</b>) Distribution of the MDVs for 1000 neurons. (<b>C</b>) PDs plotted against MDs. (<b>D</b>) PDs of the 8 muscles after learning. (<b>E</b>) Distribution of the PDVs for 1000 neurons after learning. (<b>F</b>) Polar histogram of the neuronal PDs after learning.
