Abstract :
Using a data-driven analysis of diffusion MRI called connectivity based cortical parcellation, we were able to segment the human inferior parietal lobule into spatially contiguous regions that closely match the human cytoarchitectonic atlas. This supports the cortical field hypothesis in that connectivity profiles appear to define the same field boundaries as histo-logic features. Here we present an approach and evaluation method for connectivity-based cortical parcellation.
