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...

Recent advancement in the single cell transcriptome rendered high confidence cell type catalogues on many organs, including retinal cells in zebrafish. Other than obtaining cell type identity for differentially expressed transcripts, our analysis...

..., but with different temporal patterns. It is widely known that a natural dark phase which is undisturbed by artificial light is essential for optimal circadian function. 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...
