Behavioral effects of erythrosine following light exposure.

Abstract

Three studies were conducted to examine the effects of erythrosine on the activity level of mice in a figure 8 maze. Results of the first study show that activity in a dark maze is not influenced by intraperitoneal doses as high as 1.25 mg/kg. In two additional studies, subjects were subjected to combinations of dye and pre-exposure to blue (Experiment II) or blue and green (Experiment III) light. Light exposure consistently produced increased activity levels. However, there was little evidence of a dye-light interaction effect.
