R, right; L, left; BA, Brodmann area. Cluster extension represents the number of contiguous voxels passing the threshold ofpB0.01. Bold markings delineate a cluster and the peak zvalue. Brain regions are indicated by Talairach and Tournoux coordinates, x,y, and z.x: the medial to lateral distance relative to the midline (positive: right hemisphere), y: the anterior to posterior distance relative to the anterior commissure (positive: anterior), z: the superior to inferior distance relative to the anterior commissureposterior commissure line (positive: superior).


study, this finding may also relate to the hypothesis of a rather late affection of parietal cortices, which had been expected to correlate with praxis test scores in AD patients. Concerning constructional praxis recall scores, significant

correlation with right frontal cortices occurred. Right frontal cortex activation may specifically refer to the HERA model since the delayed figure reproduction also implicates retrieval of information. Interestingly, the frontal cortex activation was
