Figure 1. — Bmal1^−/− mice locomotor activity. Mice were monitored in 12-h LD conditions for 1 wk before exposed to DD conditions for 2 wk. Analysis of DD conditions is restricted to the second week of monitoring. (A) Representative Bmal1^+/+ and Bmal1^−/− double-plotted actograms in 12-h LD conditions. Each line represents 48 h. (B) Bmal1^+/+ and Bmal1^−/− χ-square periodograms. Bmal1^+/+ periodogram reveals τ = 1445 min, or 24.1 h. Bmal1^−/− periodogram does not reveal a period of 24 h. For the one peak that does cross the line of significance, τ = 1085 min, or 18.1 h. (C) Representative Bmal1^+/+ and Bmal1^−/− double-plotted actograms in DD conditions. (D) Bmal1^+/+ periodogram reveals τ = 1410 min, or 23.5 h. Bmal1^−/− periodogram does not reveal a period of 24 h. For the one peak that does cross the line of significance, τ = 1130 min, or 18.8 h.
