(A). The average total distance moved in dark hours (ZT12–ZT24) was 188.6 cm (n = 35; SE = 34.3) compared to 84.5 cm (SE = 4.1) during light hours (ZT0–ZT12). (B). In the LD and DD experiments, the major oscillation frequency peak identified through Fourier analysis is almost exactly 24 h. In the LL experiment no significant oscillation frequency was identified.
