Graph Analysis of Brain Networks - Measures and Tools

  1. 1. 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
  2. 2. 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
  3. 3. Steps of generate structural and functional brain networks WECO Lab, CSIE dept., FJU 2010/6/2 3 http://www.weco.net
  4. 4. Computational modeling of structural and functional brain netowrks WECO Lab, CSIE dept., FJU 2010/6/2 4 http://www.weco.net

  6. 6. Network measures WECO Lab, CSIE dept., FJU 2010/6/2 6 http://www.weco.net
  7. 7. Measures of network topology WECO Lab, CSIE dept., FJU 2010/6/2 7 http://www.weco.net
  8. 8. Construction of brain networks WECO Lab, CSIE dept., FJU 2010/6/2 8 http://www.weco.net
  9. 9. 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
