Graph Analysis of Brain Networks - Measures and Tools Graph Analysis of Brain Networks - Measures and Tools Presentation Transcript

  • Graph Analysis of Brain Networks—Measures and Tools Speaker : Jimmy Lu Advisor : Hsing Mei Web Computing Laboratory(WECO Lab) Computer Science and Information Engineering Department Fu Jen Catholic University
  • Steps of Graph Analysis  Define the network nodes. (EEG, MEG, MRI, DTI, etc.)  Estimate a continuous measure of association between nodes  Generate an association matrix, a binary adjacency matrix or undirected graph.  Calculate the network parameters of interest in this graphical model of a brain network WECO Lab, CSIE dept., FJU 2010/6/2 2 http://www.weco.net
  • Steps of generate structural and functional brain networks WECO Lab, CSIE dept., FJU 2010/6/2 3 http://www.weco.net View slide
  • Computational modeling of structural and functional brain netowrks WECO Lab, CSIE dept., FJU 2010/6/2 4 http://www.weco.net View slide
  • Illustrative anatomical, functional, effective connectivity networks WECO Lab, CSIE dept., FJU 2010/6/2 5 http://www.weco.net
  • Network measures WECO Lab, CSIE dept., FJU 2010/6/2 6 http://www.weco.net
  • Measures of network topology WECO Lab, CSIE dept., FJU 2010/6/2 7 http://www.weco.net
  • Construction of brain networks WECO Lab, CSIE dept., FJU 2010/6/2 8 http://www.weco.net
  • Graph analysis tools  Brain connectivity toolbox (BCT)  A toolbox of Matlab  Contributor: Olaf Sporns, Mikail Rubinov, Rolf Kotter, Patric Hagmann  Define functions for analyzing complex graph (ex: degree, shortest path, etc.)  The functions are the collection of many research results  The web site also provide some useful information. (ex: connectivity datasets, tools for visualization, etc.)  Open source. We can define our own measures. WECO Lab, CSIE dept., FJU 2010/6/2 9 http://www.weco.net
