Although their behaviour, ecology and evolution are well studied, information on their circadian rhythms are scarce. We quantified the daily locomotor activity rhythm under a light:dark cycle (LD) and under constant darkness (DD...

Here, we show that light intensity during the photophase also plays a key role in maintaining circadian rhythms in rodents, irrespective...

In the ensuing days, an activity peak appeared in phase with the time of food delivery. The food-related activity peak could...
