Evoked potentials to pairs of click stimuli were recorded from 127 subjects ranging in age from 10 to 39 years to examine the developmental course of auditory sensory gating. The ratio of the amplitude of the second response to that of the first provides a quantitative measure of auditory sensory gating. Contrary to earlier results, the distribution of P50 ratios was unchanged between children and younger adolescents (10-14 years), older adolescents (15-19 years), and adults (20-29 and 30-39 years). Included in the sample were 39 adolescent twins, allowing assessment for possible genetic effects underlying the P50 sensory gating phenotype, by comparison of the similarity of the measure in monozygotic and same-sex dizygotic twin pairs. The monozygotic twins had significantly higher similarity for the P50 ratio within each twin pair than the dizygotic twins. These results are consistent with the presence of genetic influences on the P50 sensory gating phenotype.
