Studies involving functional connectivity of the brain are of growing interest due to its significance in understanding the underlying mechanisms of the resting brain and also its potential for clinical applications. This work involves examining the spatial consistency of functional connectivity within the primary motor cortex of the resting brain within and across sessions using test-retest methodology. Seven subjects underwent three resting state scans in each of three separate sessions for a total of nine resting state scans. In each of the sessions a functional MRI involving the motor cortex was also obtained. A generalized linear model (GLM) was used to extract voxels that were significantly correlated with the task from the functional MRI scan. The most strongly correlated voxels were used as seed voxels to generate functional connectivity maps from the resting state scans using GLM analysis.
