Bright Light Does Not Immediately Stop the Circadian Clock of Gonyaulax1

Abstract

Circadian rhythms in acid-stimulated bioluminescence and cell division are observed for at least 16 days in bright continuous light (4.5 milliwatts per square centimeter or 20,000 lux). The photosynthesis rhythm also fails to stop immediately upon transfer of cell suspensions to bright light. After about 4 weeks under these conditions, all rhythms were observed to damp out. In cells transferred from bright light to continuous darkness, the rhythms were reset to about circadian hour 12 to 14, the phase of the beginning of a normal night.
