Fig 3. Actograms of the locomotor activity and core T_b of mole-rat GC2 at 30°C, 25°C and 20°C, showing weak entrainment under the LD cycles and no obvious free-running rhythm under constant darkness.

The black and white bars on top of the actograms shows the dark and light phases during the LD cycles, during DD cycles no light is present. The number of days are on the Y-axis, and the experimental conditions are indicated between the two actograms.
