Figure 2. Regions that show differential importance in contributing to the face and word classifiers.

Shown here are the voxels with positive importance for one category classifier (e.g., faces), but with negative importance for the other (e.g., words). These voxels likely differentially contribute to the ability of the face and word classifiers to distinguish these two categories. Red indicates voxels that had positive importance for faces but negative importance for words, whereas blue indicates voxels that had positive importance for words but negative importance for faces. The spatial extent of the mask used for determining the classifier is shown in green.
