Behavioral entrainment-correlation functions. Behavioral entrainment-correlation functions relating activity and light exposures for two example nurses, one day-shift nurse (Figure 6a) and one rotating-shift nurse (6b) and two example rats, a rat exposed to a regular 12L:12D pattern of light and dark (6c) and a "jet-lagged" rat exposed to a 12:12 light-dark cycle that was phase-reversed every 48 hours (6d).
