Abstract Male mice, genetically selected for differences in brain weight or from a heterogeneous (HET) stock, were used to explore potential interactions between genotype and exposure to lead as manifested in activity. At the time of birth dams and their pups were given either water or a 0.5% lead acetate solution as the sole source of fluid. Fluid conditions remained constant throughout the experiment. The effects of chronic lead on activity in young adult mice depended on the genotype of the individual. Specifically, in an open field, HET mice exposed to lead tended to be more active than their control counterparts. Low-and high-brain weight lead-exposed mice at times were hypoactive but this effect depended on the specific nature of the measure.
