All mice were raised under normal day lengths of 24 hours during the first four weeks after birth. They were then transferred to individual cages and exposed to constant darkness (DD) for 7 days to record their free running period (FRP). After 7 days they received an additional 6 weeks of altered environment — exposed to short day length (ST) (Light:Dark 11:11), normal day length (NT) (L:D: 12:12), or long day length (LT) (L:D 13:13). After entrainment, all mice were then transferred to DD for an additional 10 days to record their FRP.
