Feeding is an integrative behavior that requires movements of the jaw to bring the teeth into contact with the food, while the tongue moves and deforms to position and manipulate the food bolus. Jaw and tongue movements during feeding have both been studied extensively, but usually separately and at specific time points within the gape cycle (minimum gape, maximum tongue protrusion). In comparison, jaw-tongue coordination has mostly been described qualitatively and only quantified at the level of the feeding sequence. Here we measured jaw-tongue coordination by testing the correlations between jaw movements and tongue kinematics continuously throughout the gape cycle. First, using XROMM, jaw pitch (opening-closing), tongue protraction-retraction, width, length and surface area were reconstructed in 7 pigs chewing on 2 different foods (apples and almonds). Then, using Functional Data Analysis, we standardized and resampled the kinematic waves and tested the bivariate correlations between jaw pitch and tongue kinematics at each timestamp, thus identifying when coordination is strongest, and when it is weakest. Our results show that each tongue variable has a different pattern of coordination with jaw opening-closing movements. The strength of the correlation is also not constant through time, but instead shifts between periods of strong correlation and periods of low, non-significant correlation. In both foods, jaw-tongue coordination is the strongest around maximum gape, but food-specific time-shifts in the coordination pattern occur during tooth-food-tooth contact.
