Scatterplot of the number of activated voxels (contralateral to seizure onset in patients with TLE) as a function of the CBZ serum level. Five patients receiving GBP and LTG as add-on therapy are indicated. The linear regression function is shown. The gray line represents the median number of activated MTL voxels (half of total number) of 20 healthy controls. Only four patients had more activated voxels than the median of controls.
