fMRI with a Siemens Allegra 3.0T scanner.
Visual presentation of line drawings from two categories: tools and dwellings. The different objects were "drill, hammer, screwdriver, pliers, saw, apartment, castle, house, hut, and igloo."
 Data analysis
A machine learning classifier was trained on 400 voxels with the Gaussian Naïve Bayes model from Learning to decode cognitive states from brain images.
