behavior/neurological
• at the onset of constant darkness heterozygous mutants begin activity slightly earlier (about 30 min) than predicted from the previous light dark cycle but not as early as homozygous mutants
• heterozygotes display a 50% reduction in the magnitude of light induced phase shifts compared to wild-type controls
