fluid access epoch (FDR-corrected rank-sum tests; p < 0.05; Fig. 1D). Differences during fluid access were expected, as drinking required that animals remain in close proximity to the sipper on drinking trials. No differences in movement speed were observed during the DS of drinking versus non-drinking trials, while transient differences were observed from the 2- to 4.5-s period following DS offset (Fig. 1D). Furthermore, no differences (main effects or interactions; p > 0.20) were observed in the mean number of drinking (number of trials ± SEM: P = 19.19 ± 1.31; Wistar = 22.40 ± 2.03) or non-drinking trials (number of trials ± SEM: P = 20.50 ± 1.34; Wistar = 17.60 ± 2.03). Collectively these data indicate that the behavioral response to the DS was not predictive of a drinking trial.
