Neural trajectories and Procrustes transformations for the motor cortex population. In each panel, the vector field indicates the direction and magnitude of the Procrustes transformation required to map the trajectories from one set of conditions onto the trajectories for another set. Left: map from load-off trajectories to load-on trajectories. Center: map from stimulation-off trajectories to stimulation-on trajectories. Right: map from slowest trajectories to fastest trajectories.
