Lateralized auditory brain function in children with normal reading ability and in children with dyslexia.
Central auditory processing in typically- and atypically-developing readers were examined. Auditory responses were strongly lateralized in control children. By comparison, children with dyslexia showed significantly less lateralisation of auditory cortical functioning, and a different pattern of development of auditory lateralization with age. These results provide further evidence that the core neurophysiological deficit of dyslexia is a problem in the balance of auditory function between the two hemispheres. However, Levinson wondered if these atypical responses in dyslexics were secondary to their disorder rather than related to its causation?
About Harold Levinson, M.D.
Formerly Clinical Associate Professor of Psychiatry at New York University Medical Center, Dr. Harold Levinson is currently Director of the Levinson Medical Center for Learning Disabilities in Great Neck, New York. He is a well known neuropsychiatrist, clinical researcher and author. His "highly original" research into the cerebellar-vestibular (inner-ear) origins and treatment of dyslexia and related learning, attention-deficit/hyperactivity and anxiety or phobic disorders has evolved over the past four decades. Levinson's concepts encompass the collective insights derived from the examinations, follow-up and successful treatment of over 35,000 children, adults and even seniors and have led to new methods of screening, diagnosis, treatment and prevention. His expanded theories appear capable of encompassing and/or explaining all reported symptoms as well as most other concepts and experimental data, thus resulting in a truly holistic perspective.
