Functional MRI experiments were carried out in 6 healthy and 2 blind subjects for sensory perceptive condition and spatial judgement at 1.5T. It was observed that blind subjects recruit neural areas responsible for visuospatial judgement for parametric identification. Visuospatial judgement recruit similar areas of the brain in visually handicapped subjects as in controls, even though they did not have any visual experience and accessed their environment using nonvisual modalities.
