             abstract = "In this work we introduce an iterative method that deforms brain 
                         models built from tomographic images. The deformation is used for 
                         normalization purposes: individual models are deformed to match 
                         the shape, orientation and internal morphology of a reference 
                         model. In this method the individual and the reference models are 
                         each enclosed in a cube which is subdivided to form a rectangular 
                         grid. The vertices in the individual model's grid are perturbed 
                         and the contents of each cell is then trilinearly mapped into a 
                         cube. The composite of all resulting cubes form the deformed model 
                         to be compared with the reference. The perturbations on the 
                         vertices are generated by a simulated annealing optimization 
                         technique. To maximize the performance, the models are represented 
                         in a multi-resolution fashion and the method is parallelized.",
