Figure 7

Three-hour phase advance of food-restriction protocol. (A) Values correspond to the hourly mean time (± SEM) of the state obtained for 8 animals under BL (cyan area) and recorded for at least one week after the phase advance of the scheduled feeding window (A-FR, yellow circles). Open squares under upper abscissa indicate significant differences with respect to BL (2-tailed paired t-test after significant 2-way rmANOVA). Horizontal white and black bars illustrate photoperiodic conditions. Yellow horizontal bar under upper abscissa and vertical dashed lines indicate the timing of the feeding window under A-FR. (B) Blue and yellow arrows correspond to BL and A-FR mean vectors. Cyan (BL) and reddish (A-FR) dots correspond to individual acrophases averaged for the corresponding vector. Note that the NREM sleep vector under A-FR is not significant. Radial ordinate corresponds to the magnitude (r) of the mean vector (total radius = 0.5). Yellow arc indicates the feeding interval in its advanced position.
