Effect of maternal separation on the responsiveness to melatonin in food anticipation. Analysis of food anticipation for the second feeding time point (1 hr prior to lights off) according to the previous (stage 2) 11:11 hr light: DimLight cycles for animals subjected to constant dim light conditions, measured as changes in spontaneous locomotor activity. Mean spontaneous locomotor activity profiles were averaged into 10 min bins for both peer-reared and mother-reared groups either treated with vehicle in stages 1–3 (A, C) or with melatonin in stage 2 (B, D). *P < 0.05, One-way ANOVA and Newman–Keuls post hoc analysis. Error bars represent s.e.m. Identical letters are assigned to identify time intervals compared by Newman–Keuls post hoc analysis. Data presented are normalized to baseline activity.
