Abstract

The functions of the sensory systems on disabled people have been one of the most investigated topics in brain research. In these studies, mostly visual stimuli had been employed while investigating the deaf participants. Limited number of electrophysiological studies revealed better visual sensory processing in deaf participants. On the other hand, studies deploying tactile stimuli especially used either electrical or painful stimulus or they focused the psychophysical assessments of thresholds associated with tactile stimuli. The present study tried to evaluate electrophysiological brain responses in deaf and control group with a unimodal study design including both the visual and non-painful tactile stimuli, and to reveal the possible changes in brain plasticity within modality basis.
