A significant component of diffuse brain injury (DBI) is diffuse axonal injury (DAI) which is responsible for the morbidity and mortality associated with this condition. DAI and its experimental counterpart traumatic axonal injury (TAI) result in scattered microscopic pathology characterized by focal impairment of axonal transport leading to progressive swelling and delayed axotomy. DBI-mediated perisomatic axotomy does not result in acute neuronal death suggesting that delayed axotomy was responsible for this unanticipated response. To evaluate this hypothesis, we examined the spatiotemporal progression of DBI-mediated perisomatic TAI. LM / TEM identified impaired axonal transport within 15 - 30 min post-injury. Perisomatic …
