Effects of treadmill running on circadian rhythms in mice grouped by lesion catagory

Group Period (hr)1-a Entrained (%) Period or phase change
Intact 1 23.53  ± 0.05 14 /16 2 /16
Intact 2 23.55  ± 0.06 8 /9 1 /9

5-HTx complete1-c 23.61  ± 0.06 0 /14 12 /14
F1-a

 Free-running period measured before the treadmill schedule, except for Intact 2 measured during the first week of the treadmill schedule (see Results for further explanation). No significant differences across groups.

F1-b

 All but one SCN-ablated mouse were arrhythmic before the treadmill schedule.

F1-c

 Includes 10 mice with no 5-HT-IR in the SCN and 4 mice with a few scattered 5-HT fibers.
