t statistic and p values are listed for each cortical area in each subject. Entries in boldface indicate statistical significance at p < 0.05, one-tailed t test (hull hypothesis, mean of 0). DOF (degrees of freedom) = n − 1, where n is twice the number of scans (assuming that the measurements were statistically independent in the two hemispheres).
