Addressing the issues of reliability, specificity, and standardization can be greatly facilitated by following the general guidelines for ERP research (Duncan et al., 2009). A proper quantification of event-related brain activity (e.g., using principal or independent components analysis to separate overlapping components of response when needed) is essential for the identification of genetic factors influencing neural activity associated with specific cognitive processes. While the use of alternative representation of event-related response may be well justified, it can be recommended that traditional peak and latency data are also presented to ensure comparability across studies.
