Single trial and averaged tongue trajectories centered to inhibition of frontal , parietal and frontolateral nodes. Control . Note that trajectories evolve from top to bottom with the mouth at top and pellet at bottom . Upward change in value indicates decrease in tongue length.Distribution of total tongue length 0.5 s before and after inhibition onset of frontal , parietal and frontolateral nodes.
Right: Mean vertical hand trajectory from side view and absolute velocity during control and inhibition of frontal , parietal and frontolateral nodes. Insets: zoomed mean signals. Note increase in velocity fluctuation during parietal inhibition.Distribution of absolute velocity integral for 1 sec post hand lift during control and inhibition of frontal , parietal and frontolateral nodes.
