Inferring functional connectivity using spatial modulation measures of fMRI signals within brain regions of interest
2008
2008 5th IEEE International Symposium on Biomedical Imaging: From Nano to Macro
We propose inferring functional connectivity between brain regions by examining the spatial modulation of the blood oxygen level dependent (BOLD) signals within brain regions of interest (ROIs). This is motivated by our previous work, where the spatial distribution of BOLD signals within an ROI was found to be modulated by task. Applying replicator dynamics to our proposed spatial feature time courses on real functional magnetic resonance imaging (fMRI) data detected task-related changes in the
