    Program to Help Families Facing Autism Challenge

    Reaching out to families touched by autism, the UT Dallas Callier Center for Communication Disorders is offering a pilot program to help parents facing a child's new diagnosis.

    Strategy Training and Response to Therapy (START) focuses on children 18 months to 5 years old who have been recently diagnosed with an autism spectrum disorder and who have received an autism assessment through Children’s Medical Center of Dallas..

    A Cure For Tinnitus at UTD?

    A promising new therapy has made its way from Australia to the States. The Callier Center for Communication Disorders at University of Texas at Dallas is one of about 200 medical centers offering Neuromonics, a treatment device for tinnitus developed by an Australian audiologist, Dr. Paul Davis.

    Dallas audiologist Anne Howell, head of Callier's tinnitus clinic, says the treatment works by retraining neural pathways in the brain. As a result, the auditory system is desensitized to the sound.

Auditory training alters the physiological detection of stimulus-specific cues in humans

Posted by Callier Library on December 4, 2008

Results
The P2 wave increased in amplitude after training for both control and experimental stimuli, but the effects differed between stimulus conditions. Whereas the effects of training on P2 amplitude were greatest in the left hemisphere for the trained stimuli, enhanced P2 activity was seen in both hemispheres for the control stimulus. In addition, subjects with enhanced pre-training N1 amplitudes were more responsive to training and showed the most perceptual improvement.

Conclusion
Both stimulus-specific and general effects of training can be measured in humans. An individual’s pre-training N1 response might predict their capacity for improvement.

Significance
N1 and P2 responses can be used to examine physiological correlates of human auditory perceptual learning.
