Data are plotted in Figure 2C–E. Units are in seconds, and values are reported as the mean ± SEM (sample size). For the total cycle time (Fig. 2C) and duration between inward movements (Fig. 2E), the numbers of swallows are smaller for some animals compared with the duration of inward movement (Fig. 2D) because swallows preceded by another whose inward movement could not be reliably measured were dropped. sig., Significant test results; n.s., nonsignificant test results.
