Abstract

Pattern reversal evoked potentials (PREPs) were studied in school going children 4-15 years of age (mean 9.9 +/- 2.6 yrs), using Ag/AgCl electrodes anchored on 01-A1 and 02-A2 scalp sites. Two sets of 256 pattern reversal stimuli with check sizes 32' and alternation rate 1 Hz were applied to each eye and evoked responses thus obtained were averaged and analysed by the inbuilt computer of the evoked potential recorder. The latency of various components of visual evoked potentials along with P1 amplitudes were recorded for the right and the left eye separately in boys and girls. The normative data are being reported and these do not show eye and gender differences in children.
