Pattern visual evoked cortical potential waveforms and spatial frequency characteristics in children. 1988

Department of Ophthalmology, School of Medicine, Chiba University, Japan.

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.

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D014792	Visual Acuity	Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.	Acuities, Visual,Acuity, Visual,Visual Acuities
