Specificities of EEG Activity of the Visual Neocortex in Adolescent Boys with Congenital Visual Dysfunctions

  • Published:
Neurophysiology Aims and scope

We compared the results of spectral/coherent and nonlinear analysis of EEGs recorded in adolescent boys with congenital visual dysfunctions and boys with normal vision. In the former group, an intensified functional activity of the visual neocortex in a relaxed wakefulness state was observed in the left hemisphere. Such a pattern was also found in the course of auditory-motor integration, but the manifestations were bilateral.
