Fig. 7. (A) Velocity and (B) acceleration traces of the point of bifurcation of the
tongue along the covered trajectory for the three tongue flick clusters shown
in Figs 5,
6. The range of the time axis
is chosen to represent the time interval that the tongue tips are visible for
each of the three tongue flick clusters. The blue curve indicates forward
velocity and acceleration, the red curve indicates lateral velocity and
acceleration and the green curve indicates vertical velocity and
acceleration.
