FIGURE 6 Illustration of the utilization of anatomical landmarks to evaluate algorithms for deformation into a stereotactic space. The probabilistic maps of the precentral and central sulci, the Sylvian fissure, the parieto-occipital sulcus, and the calcarine sulcus are given after two different normalization procedures . The warmer the color, the more frequent the sulcal recovery. The nonlinear method shows better segregation of the Rolandic and precentral sulci, especially in the right hemisphere. See also Plate 63.

FIGURE 7 Probabilistic map of cingulate and paracingulate sulci of the internal surfaces of both hemispheres in 247 subjects ; the left hemisphere is on the left. The larger the probability, the warmer the color. The main result is that in the left hemisphere one may identify the paracingulate sulcus, showing a larger development of the left anterior cingulate. The authors relate this result to the left hemisphere specialization for language. See also Plate 64. Reprinted with permission from T. Paus, F. Tomainolo, N. Otaky, D. MacDonald, M. Petrides, J.
