Motion onset-offset VEPs in children.
We analysed motion onset-offset visually evoked potentials (VEPs), pattern appearance-disappearance VEPs and pattern reversal VEPs recorded in 23 adults and 37 children, ranging in age from 5 to 12 years. Motion-specific responses (i.e., responses that could not be attributed to the changes in contrast that are associated with the onset and offset of motion) were found in 25 children (67.6%) and in 19 (83%) adults. These percentages do not differ significantly. Also the age distributions of children with and without motion-specific VEPs do not differ significantly. For these reasons no development of motion VEPs with age could be established, in contrast with the well-known maturation of the pattern appearance VEPs.
