Neuroimaging Investigations of the Mind and Behavior

Erin Bigler
Professor of Psychology and Neurology
Brigham Young University

Neuroimaging, in particular magnetic resonance imaging (MRI), has revolutionized the study of the brain. MRI techniques like diffusion tensor imaging (DTI) permit the study of aggregate pathways in the brain, which in turn allows the investigation of connectivity within the brain that is associated with behavior. Functional MRI (fMRI) permits the investigation of neural correlates of brain activation associated with a particular behavior. New image-analysis techniques allow quantification of the entire brain, so that the volume of each brain structure, their contour and shape can be quantified along with thickness of the gray matter of the cortical mantel. All of these methods are being applied to the study of neuropsychiatric and neurological disorders. This colloquium will review all of these methods and how they have improved our current understanding of the neurobehavioral relationships observed in developmental disorders like autism and acquired brain injury.
