Fig. 3From: Identification and functional analysis of early gene expression induced by circadian light-resetting in Drosophila Light response in mutant flies and their background controls. Phase delays in locomotor activity following a light pulse at ZT 15 (relative to unpulsed flies) are shown. The error bars were based on SEM of each genotype from an independent t test (n = 32 flies). ** p < .0001; * p < .05Back to article page
