P300 from families.
The P3(00) event-related brain potential (ERP) was elicited using auditory and visual stimuli in an oddball paradigm in 10 families, each consisting of a biologically related father, mother, and 2 children. P3 amplitude and latency measures from both stimulus modalities were more highly correlated between family members than between non-family individuals. Similar effects were found for the N1, P2 and N2 components. The results support findings from twin studies suggesting that genetic factors contribute to P3 morphological characteristics.
