The P300 component of the auditory event-related potential in monozygotic and dizygotic twins.
The P300 component of the auditory event-related potential was recorded from 10 pairs of monozygotic (MZ) twins and 11 pairs of dizygotic (DZ) twins during an auditory discrimination task. The within-pair similarity of P300 latency was significantly greater in MZ than in DZ twins. The within-pair similarity of P300 amplitude was not significantly greater in MZ than in DZ twins. These results support previous findings suggesting that P300 latency is largely genetically determined.
