Relationship between the Consciousness State and the Default Mode Network in Traumatic Brain Injury

Abstract: Introduction:This study investigated the relationship between Coma Recovery Scale-Revised (CRS-R) and the neural networks between the medial prefrontal cortex (mPFC) and precuneus (PCun)/posterior cingulate cortex (PCC) in disorders of consciousness (DOC) patients with a traumatic brain injury (TBI) using diffusion tensor tractography (DTT). Measures: Twenty-five consecutive patients with TBI admitted to the rehabilitation department of a university hospital were enrolled in this study. The Coma Recovery Scale… Show more

“…Fiber tractography is determined using the constrained spherical deconvolution method described by Tournier et al 9 A machine-learning model then computes the most likely parcellation on a voxel-by-voxel basis based on structural connectivity and a match to an augmented Human Connectome Project atlas of task-based and resting-state fMRI. The result is a patient-specific parcellation and white matter fiber map for several well-known connectome networks, including the default mode network (DMN), 10,11 optic radiation (OR), 12 and central executive network (CEN). 13-15 The network data were in-turn converted to a set of “burn-in” images where the voxel data containing network parcellation or fiber tracts were set to the maximum voxel value for the data set.…”
