All experiments were performed in 12L:12D unless otherwise indicated. All mice had intact (not lesioned) SCN unless otherwise indicated. RF: restricted feeding; FAA: food anticipatory activity; ND: not determined; CR: caloric restriction
Note that data collected under conditions of restricted feeding with purposeful caloric restriction are not presented herein
Experiments were performed in 13L:11D
FAA was also present in constant darkness (Lamont et al., 2014)
