ReentrainmentAbsent (150 lx)Most animals unable to entrain (700 lx)
Advanced onset
Others had light responses, but no stable circadian rhythms
Half able to entrain, more than 16 days required (100 lx)

Half failed to entrain
Able to entrain, more than 12 days required (15 lx)
Normal (300 lx)
Able to entrain, at least 8–11 days required (100 lx)
