DOI: 10.1002/cnm.3570
Abstract: Spinal cord impacts can have devastating consequences. Computational models can investigate such impacts but require biofidelic numerical representations of the neural tissues and fluid–structure interaction with cerebrospinal fluid. Achieving this biofidelity is challenging, particularly for… read more here.
