(AB). Average calcium transients in response to familiar (HH and DD groups) or novel (DH and HD groups) food. Traces represent the average percentage change from baseline over time of the fluorescence emission ratio of the ratiometric calcium sensor Cameleon YC3.60. Dashed line at t = 0 represents the time at which the stimulus is delivered. The number of individual recordings is indicated in parenthesis next to each group. (C) Average response to familiar or novel food. The bars represent the average signed area below ΔR/R between t = 0 and t = 120 s. Data shown as mean ± SEM, *p < 0.05; one-way ANOVA, post hoc Tukey test.
