Figure 3.

Two examples of vertical jaw and soft palate movements over time with concurrent respiratory patterns in processing cycles while participants were eating a cookie. These feeding sequences were in different participants. Upward movement is shown as upward deflection on the graph. The inspiratory and expiratory phases are shown in gray and white, respectively. (A) Cyclical elevation of the soft palate was temporally linked to rhythmic jaw movement during expiration, but soft palate elevation was minimal during inspiration. (B) Soft palate elevation was temporally linked to jaw movement in every cycle. However, the amplitude of soft palate elevation was smaller during inspiration than expiration.
