Analysis of neuroimaging data

direct-gazeMagnetoencephalography (MEG) is a form of neuroimaging that can be used to assess activity in various brain regions. Working with researchers from the University of Michigan Department of Psychiatry, CSCAR consultant Dave Childers used spectral coherence analysis to examine connections between pairs of brain regions. Since there are over 50 brain regions, and 1400 pairs of regions, a direct analysis would produce an overwhelming set of results that would be difficult to interpret. Modern methods for statistical error control allow false positive associations to be limited, while still retaining power to detect potentially important differences between the study groups.
