Correlation between performance accuracy and RT during the visuomotor learning task and CBV/CBF values for CIS patients. Zero-order Pearson correlation coefficients between performance accuracy (a) and RT (b) during the visuomotor learning task and CBF/CBV in 20 ROIs in the left (L) and right (R) hemispheres and the corpus callosum. Coefficients > 0.50 were significant at a Bonferroni-corrected alpha level of .0025 (indicated by horizontal solid lines). Asterisks indicate significant correlations which were also found to be condition specific (based on Fisher's z test for the difference between correlation coefficients in the “simple” and “executive” conditions).
