Functional MRI Data Analysis Using Connectivity Strengths to Identify Cognitive States

This paper considers a graphical framework for identifying connectivity strengths in cognitive dataset. Functional MRI (fMRI) data with two cognitive states used for the analysis. In general fMRI data expressed in terms of number of voxels and Region of Interests (ROI). Task specific brain activation detection using fMRI is a challenging activity. The connectivity analysis among the ROIs gives inference about connectivity strengths among ROIs....
