Visual Electrophysiology and Reading/Learning Difficulties

Abstract

The literature relating visual problems, reading and academic difficulties with neurophysiological mechanisms shows positive interaction among these factors. Both visual evoked response and encephalographic studies show parietal or occipitoparietal neurophysiological anomalies which can be used to discriminate between normal and disabled readers to better than an 85% accuracy. Visual training and visual biofeedback have been used to change encephalographic alpha rhythm patterns with concomitant changes in attention and reading skills.
