P300 from identical twins.
The P300 component was obtained from ten pairs of identical twins and matched control subjects with an auditory discrimination task. The event-related brain potentials (ERPs) from the identical twins were strikingly similar in amplitude and latency compared to control subject pairs. The data suggest that individual variations in ERP waveform morphology are determined by the structure of the neurophysiological mechanisms responsible for P300 generation.
