Development of Novel Methods to Investigate the Brain at Rest

Brain function appears to be highly organized even inthe absence of specific tasks. In this work we usegraph theory in a multimodal neuroimaging experiment employing functional magnetic resonance imaging and near-infrared spectroscopy to better understandfunctional connectivity during theresting state. Our results suggest that, despite differences across subjects, theirgraph properties arevery similar. In addition, we propose a novel approach to analyze group connectivity based on frequency distribution of the links.
