The wavelength dependence of three different circadian responses to light was compared in Syrian hamsters: phase advances and phase delays induced by 15-min light pulses at CT18 (circadian time 18) and CT13, respectively, and changes in free-running period under different levels of constant illumination (LL) intensity. Fluorescent lamps with transmission maxima at 436, 514, and 658 nm were used for delivering blue, green, and red light, respectively. White fluorescent light was also used in the… CONTINUE READING
