This study creates age and gender-stratified group-average brain models to analyze biomechanical responses to traumatic brain injury, finding significant demographic differences in deformation patterns.

This study uses magnetic resonance elastography to assess brain mechanical properties and perineuronal net density in a rat model of FASD, showing reduced stiffness in alcohol-exposed rats that recovers by adulthood.

This study uses anisotropic MR elastography to show age-related declines in white matter mechanical properties, providing complementary information to diffusion tensor imaging.

This study uses magnetic resonance elastography to measure mechanical properties of post-mortem human brain tissue and track changes over time, revealing stiffness and damping ratio trends.

This paper uses contrastive learning on regional biomechanical properties from MRE to improve brain age prediction and detect neurodegeneration, finding that stiffness and damping ratio are sensitive biomarkers for Alzheimer's and MCI.
