Coherent relations between EEG signals of five frequency ranges recorded from different cortical sites were evaluated in 8- to 12-year-old children with congenital and acquired visual dysfunctions; the results were compared with those observed in children with normal vision. In visual dysfunctions, the coherence was, in general, higher for slow-wave ranges and weaker for the alpha EEG range. These facts are indicative of probable intensification of brainstem influences of the cortex. Specific features of the coherence dependent on the time of development of visual dysfunctions were identified.
