Figure 2. Circadian and Diurnal Behavior of cwo Mutants Under Constant Darkness and Light-Dark Conditions.

(A-C) Behavior under constant darkness conditions of cwoe/+ (A) (n=80), Df(3R)5495/+ (B) (n=89), and cwoe/Df(3R)5495 (C) (n=43). White and black boxes indicate light and dark periods. Gray boxes indicates subjective day in constant darkness. (D-F) Normalized activity profiles during diurnal conditions of cwoe/+ (D) (n=77), Df(3R)5495/+ (E) (n=79), and cwoe/Df(3R)5495 (F) (n=35). Light and dark bars indicate activity during the light and dark phase, respectively. N experiments= 2-4. Numerical values indicate measures of morning anticipation. Error bars indicate SEM.
