Behavioral Feeding and Swallowing Assays of Young Mice: A) Videofluoroscopy swallow study stills with black arrows indicating the food bolus at the valleculae in the frame immediately prior to a swallow (left), and a subsequent frame showing the bolus in the esophagus (right). B) Left panel: Videofluoroscopic swallow study (VFSS) analysis of a cheese puree, showing the number of swallows per 2-second intervals. Means and SEM. Right Panel: Inter-swallow Intervals, measured in seconds, quantified from the same studies. Means and SEM. C) Mastication rate during feeding on a hard food pellet, assessed by videorecording.
