Cross-modal plasticity is the ability of the brain to reorganize and make functional changes to compensate for a sensory deficit. For example in blind individuals, brain areas typically dedicated to visual perception often become co-opted by the auditory and the touch sense. Touching activates higher-level brain areas needed for recognition and reaction. In blindness, touch strongly activates visual brain areas. Activation of these visual regions might be essential to the enhanced touch skills of the blind. After years of being sightless. The unused visual brain is able to reassign itself to the service of touch.
