Table 3.

Optimal area set and associated discriminative weights for RCK analysis applied to GLM data. The most informative anatomical regions retrieved by RCK when applied to GLM data are grouped in macro brain regions to give a better idea of their location in the brain. The mean and the standard deviation of the discriminative weights of each area are listed in this table. In addition the rate of training sets in the cross-validation procedure that selected each area (selection frequency) is also reported in order to measure the validity of the inclusion of each region in the optimal area set.
