Abstract. The quantitative analysis of the geometry of the human brain cortex is an important goal of neuroscience research. A specific area of interest is the analysis of the various anatomic regions of the human cortex. Developments in medical imaging techniques, in particular magnetic resonance imaging, have allowed for high-resolution, high-contrast images of the brain to be acquired in vivo. This has led to the development of surface models of the human cerebral cortex from these images. In this talk, I will describe the development of a methodology for the segmentation of anatomic regions of interest from a surface model of the human brain cortex and the subsequent analysis of these regions in the context of an aging study. One of the key challenges is the definition of anatomical regions on the human cortex and techniques to robustly segment them.
