Neuroimaging results.

<p>(a) Differential tactile activation maps contrasting the blindfold and non blindfold groups are shown for each fMRI session of the study. (b) A region of interest (ROI) was defined by the area of occipital activation found on day 5 in the group maps. The average differential tactile activity between groups in this ROI is plotted here in z-score units across days of the study. The difference between groups was significant on day 5, as expected from the definition of the ROI, but did not reach significance on any other day.
