Sustained and Transient Channels in Reading and Reading Disability

by Bruno G. Breitmeyer, Sarah F. Wright, Rudolf Groner.

Presents a review of research on the role of sustained and transient channels of the visual system in reading and reading disorders. The inhibition of sustained channels by transient channels is described as an important neural mechanism in the saccadic suppression that underlies identification of visual patterns in the reading process. Empirical findings indicating a deficit in transient channels in approximately 70% of the cases of reading disorders are presented. Treatment of this deficit with colored lenses or overlays is described, and implications of a transient-channel deficit for the auditory and somatosensory systems are discussed.
