Objective
To use structural equation modeling to compare attentional circuitry within the legacy set of 28 schizophrenic subjects who performed similar attentional tasks in both a PET and fMRI scan.
Progress
The data have been analyzed and segmented into a Talairach-based analysis. The mean glucose metabolism has been measured in the PET data on a region by region basis and the mean contrast values in the same regions have been measured in the fMRI data. A structural equation model is being defined for comparison among the two datasets. However, the segmentations are crude at best, and once the methods have been implemented on these regions, a second analysis using the improved segmentation methods will be implemented using FreeSurfer derived segmentations.
