Figure 7. The maintenance of negative masking in mice lacking melanopsin.

Figure 7

(A) Actograms from representative WT (n = 16) and MKO mice (n=13): Days are indicated on the left and time during the day is indicated on the top. Light period was between 0600–1800 hrs and the dark period was between 1800-0600 hrs. The dashed rectangle (Day 6) indicates the period when the light pulse was given (1900-0100 hrs). (B) Total counts/hr during the light and dark periods is shown in both WT and MKO mice. *p < 0.01, by unpaired Student’s t test. (C) Masking of locomotor activity given as percentage of baseline in WT and MKO mice. ****p < 0.0001, by unpaired Student’s t test. (D) Hourly activity count is shown across the dark period in WT and MKO mice. *p < 0.01, **p < 0.01, ****p < 0.0001, by Bonferroni’s post-hoc test. #p < 0.01, by unpaired Student’s t test. Data represents mean ± SD.
