SPATIAL MODELING AND fMRI

by

Patrick Carmack, Ph.D.
University of Central Arkansas
University of Southwestern Medical Center at Dallas


Abstract

fMRI naturally lends itself to spatial modeling (kriging). The basics of kriging along with some of the more recent modifications researched by our team will be presented. Finally, the efficacy of the new methodology will be explored via simulation and an application to a novel fMRI threat experiment with comparisons to a voxel wise analysis.

Biographical Note

Dr. Patrick Carmack, in conjunction with researchers at The University of Texas Southwestern Medical Center at Dallas and Southern Methodist University, is pioneering the use of spatial statistical modeling to analyze brain scan data to identify specific areas of the brain affected by various diseases. The new techniques have already been successfully applied to compare three-dimensional Single Photon Emission Tomography (SPECT) brain scans of people suffering from the Gulf War syndrome with those of a healthy control group.

His current research is focused on extending the current three-dimensional methodology to four dimensional fMRI data to identifying these differences in brain activation from locations deep within the brain. Spatial modeling uses information from neighboring locations to strengthen weak signals in active brain locations so they can be reliably detected.
