A statistical damage model for coupled mechano-electrophysiological axonal injury.

A novel axonal deformation damage model accurately reproduces neuro-electrophysiological responses under various stretching conditions, capturing sodium left-shift phenomena.

• Why it matters: Understanding the effects of white matter nerve stretching on electrical signals is crucial for improving clinical treatments of CNS injuries, yet existing models fail to fully describe experimental results.
• What they did: The model incorporates coupled effects of sodium and potassium channel damage, mechanical property differences among axons, and uses statistical distributions to represent injury variability, building on prior research.
• The result: This model demonstrates good universality and offers a mechanical mechanism-based reference, potentially guiding future clinical strategies for nerve injury treatment.
