Serotonergic signaling accelerates slowdown upon re-feeding. a The mean speeds of wild-type 5-HT-deficient strains around the time of encounter with the edge of a large bacterial lawn (shown without standard errors as a guide to the eye; see summary statistics in next panel). b The speeds of the strains shown in panel (a) shortly after the encounter and 20 min later. Twenty minutes after the encounter, wild-type and tph-1 center of mass speeds were similar. Bars depict mean ± SEM and the number of animals assayed for each strain is noted in parentheses. Mean velocities were compared to wild-type using an ANOVA test and corrected post hoc for multiple comparisons using Tukey’s honest significant difference (HSD) test. Double asterisks denote a significant difference from wild-type (P <0.01). For Ptph-1::TeTx and Ptph-1::tph-1, three independent transgenic lines were assayed and one representative dataset is shown
