Atlas of impact-induced, in vivo human brain kinematics

Accelerations cause brain tissue to move, and this data summarizes MRI-based observations of 3D brain movement during an in vivo impact (brain-skull displacement and brain tissue deformation). The data is a group average, or atlas, of indivudial data from two groups of study participants: neck extension (n=10) and neck rotation (n=9). Methods Brain tissue motion data was extracted from MRI sequences acquired while the heads of study participatns were subjected to a mild acceleration inside the MRI scanner. The resulting resulting images were processed using a tissue tracking algorithm. The output of the algorithm consisted of skull-brain displacements and strains in each of the participants. This data consists of a group average across the individuals i.e., a representative movement pattern of displacement and strain, as well as its varability.
