ENVIRONMENTAL light is the dominant temporal cue for the entrainment of circadian rhythms. In mammals, light entrains circadian rhythms by daily resetting a pacemaker located in the hypothalamic suprachiasmatic nucleus (SCN)1,2. Although it is widely held that phase resetting by light involves cellular elements within the SCN that are uniquely responsive to photic cues1,3, we now report that non-photic cues that reliably precede the onset of light can, through associative learning, come to… CONTINUE READING
