A–C. Average licking rhythms of mice during entrainment to T22 (A), T24 (B) and T26 (C). Shown are activity profiles over 24 to 30 cycles at their respective environmental period, T, and averaged across the 7–8 animals in each group. Profiles are scaled from zero to the averaged group maximum. Shading indicates the half of the cycle in darkness. D-F. Representative double-plotted licking rhythms of individual animals maintained continuously in T22, T24, and T26, respectively. Examples of animals transferred from T22 or T26 to T24 are not shown. G. Mean (± SEM) phase angle of entrainment for drinking rhythm relative to lights off (negative number indicates drinking begins ahead of lights out). H–I. Mean (± SEM) ethanol intake per 24 h (g/kg) and alcohol preference by group.
