title: Pattern visual evoked cortical potential waveforms and spatial frequency characteristics in children.
abstract: Development of visual evoked cortical potential waveforms and the spatial frequency characteristics of the pattern reversal stimuli were studied in children from 7 weeks to 15 years of age. All subjects were born at term. Waveforms were found to change rapidly during the first several months after the birth, from single slow positive peaks to negative-positive-negative complex. Spatial frequency characteristics in N2 latencies were observed to develop rather slowly up to school age. Long-term development of pattern vision in children was suggested.
