Slow cortical potentials were studied in young children with blood lead (PbB) levels ranging from 6 to 52 g/dl. Slow wave (SW) voltage recorded from the scalp during sensory conditioning varied as a linear function of PbB level and age. Evidence of a persistent alteration of brain function was also found in a two-year follow-up assessment of the children.
