Entrainment of the circadian rhythm in the locomotor activity of Mus booduga by red and white light.
The role of red light (greater than 610 nm) and white incandescent light in entraining the circadian locomotor activity rhythm of the field mouse Mus booduga has been studied using different light intensities. Red light of less than 150 microW/cm2 caused negative masking and greater than 150 microW/cm2 caused entrainment. Such intensity dependent masking and entrainment were also obtained with white incandescent light.
