In a previous behavioral study, it was shown that early blind individuals were superior to sighted ones in discriminating two-dimensional (2D) tactile angle stimuli. The present study was designed to assess the neural substrate associated with a haptic 2D angle discrimination task in both sighted and blind individuals. Subjects performed tactile angle size… (More)
FIGURE 5 | Brain areas where activity predicted IPTs. Shown here are occipital areas where BOLD activity during right hand exploration in blind subjects significantly correlated with the IPTs. No correlations involving occipital areas were found for left-hand stimulation or for either hand in the sighted subjects.
