Abstract
The objective of the present work was to determine the physiological m echanisms underlying the synchronization of the ERG amplitude rhythm. Chronic ERG recordings were obtained from juvenile instars of crayfish . Changes on the ERG amplitude rhythm produced when 30 min blue light illuminated the telson were determined. The PRC obtained with these da ta showed advances in the early subjective night and delays in the lat e subjective night. These phase shiftings resemble the features of cur ves obtained by dark pulses in other species. The relation of this cur ve with PRCs generated in the crayfish and other animals species are d iscussed.
