Previous studies suggest autism has atypical brain connectivity patterns. In this study, we introduce human brain connectome techniques to investigate the autistic brain in a network level. A total of 49 autistic children and 51 typically developed controls were selected from NDAR. We constructed the brain connectome analysis using 68 cortical regions as nodes and their inter-regional cortical thickness correlations as edges. Results show that autism has more weights of connections for the regions with self-related functions. Increase within frontal lobe and the decrease in frontal-related connections were found, which may contribute to the re-organization of autistic brain.
