Cross-sectional and longitudinal clinical research studies of traumatic brain injury using diffusion tensor imaging (DTI), functional MRI (fMRI), 3D MR spectroscopic imaging, and magnetoencephalography (MEG)

NIH-funded cross-sectional and longitudinal clinical research studies of traumatic brain injury using diffusion tensor imaging (DTI), functional MRI (fMRI), 3D MR spectroscopic imaging, and magnetoencephalography (MEG), with correlation to candidate susceptibility genes and to neurocognitive function (attention, memory, information processing speed, and executive function).
