Frequency analysis of electroencephalograms and latency of photically induced average evoked responses in children with ariboflavinosis. (Preliminary report.).

Frequency analysis of electroencephalograms and estimation of the average latency of photically induced evoked responses were carried out on children aged 8 to 9 years with or without ariboflavinosis associated with low serum folate activity. In the ariboflavinotic children, there was a tendency toward prolonged latency of the photically evoked responses and toward an increase in energy percent at the theta band associated with a decrease in energy percent at the alpha band of frequency in the basic wave.
