Abstract

That light and melatonin rhythms provide both clock and calendar information in humans and numerous other species is beyond dispute; this holds true for all stages of life, including the very early ones. Experimental evidence elucidates that exposure to light and melatonin titres are keys for the very development of circadian and seasonal rhythms. As evinced by a 2011 publication in Nature Neuroscience such awareness could impact considerably on the design and conduct of experimental studies as well as their subsequent analyses, interpretations and comparisons. Therefore "when and how experimental animals were bred, developed and raised" may be critical when experimenting with animals generally, and not just rodents. As long as the suggested imprinting of circadian system stability via light cues is not falsified, the perinatal season or perinatal experimental light:dark [L:D] conditions that an animal was kept under should be routinely recorded, published and considered in analysing and interpreting study data.
