Representative double-plotted actogram of locomotor activity for a (A) wildtype C57BL/6J (WT) and a (B) Cryptochrome-deficient (Cry1−/−, Cry2−/−, labelled CRY dKO) mouse using the DVC system. Animals were exposed to one week of 12:12 Light-Dark (LD) cycle and 10 days of constant darkness (DD). Yellow shading indicates light phases, while blue and orange lines depict activity onsets.
