Figure 3. Light-induced phase shifts of the circadian locomotor activity rhythm after occluder reassignment.

Figure 3

A–D Representative double-plotted locomotor activity records of Syrian hamsters bearing: A occluders in both eyes (BB→BB), B an occluder in the right eye (BR→BR), C an occluder that was moved from the right eye to the left on week 10 (BR→BL), and D a clear lens in the right eye (CR→CR). Clock time is indicated on the horizontal axis along the top of each actogram. Lights on/off are indicated by light and shaded areas of the actogram. E Mean (± s.e.m.) daily locomotor activity onsets of hamsters bearing ocular occluders during the 3 weeks immediately following a 5-hour phase advance of the light-dark cycle. * p<0.05 vs. all other groups, # p<0.05 vs. the CR-CR group.
