title: Developmental changes in human infant visual-evoked potentials to patterned stimuli recorded at different scalp locations.
abstract: Visual-evoked potentials (VEPs) to patterned stimuli were recorded from 4 different scalp locations in 2 groups of infant subjects (ages 6 weeks and 10 weeks). Seven VEP components were identified that changed in amplitude as a function of changes in the amount of contour in the stimuli presented. Developmental shifts in these effects were interpreted to indicate a change in the physiological locus of control of infant visual preferences from a subcortical to a cortical locus over the age range examined.
