Sentences with phrase «functional connectivity analyses»

With NIH funding of the Human Connectome Project (http://www.humanconnectomeproject.org), the field of AAN connectomics is now expanding due to ultra-high resolution HARDI techniques for structural connectomic analyses and resting - state functional MRI (rs - fMRI) techniques for functional connectivity analyses.

Functional connectivity is typically measured using one of three approaches: (1) regression analysis using a seed region of interest (Greicius et al., 2003; Fox et al., 2005), (2) full or partial correlation analysis of multiple regions of interest (Ryali et al., 2012), or (3) independent component analysis (ICA) of the entire imaging dataset to identify spatial maps with common temporal profiles (Beckmann and Smith, 2004; Cole et al., 2010).
