Evaluation of Auditory Processing in Blind People: A Comparison of Semantic and Auditory Perception

Ankeeta Sharma¹, Senthil S. Kumaran¹, Rohit Saxena²

Blind Children show altered brain activity in early visual cortex and develop their hearing better to compensate the loss of vision. We evaluated BOLD activity due to sounds, orientation and semantic processing through auditory cues in late blind subjects. Auditory and perception discrimination showed cross-modal activity in visual cortex, suggesting that reorganization may be limited to perception and less affected by attention.
