Source localization of event-related potentials to pitch change mapped onto age-appropriate MRIs at 6Â months of age

► Infant ERPs show adult-like change detection responses using 3 Hz high-pass filter. ► Pitch change elicits a frontocentral negative change detection ERP in 6-month-olds. ► Infant change detection response is followed by attention switching. ► ERP generator locations adjoin auditory cortices and anterior cingulate cortex. ► Locations for these two responses are in adjacent cortices and temporally distinct.
