Synaptic Mechanisms of Blast Induced Brain Injury
Frontiers in Neurology, 2016 Blast wave-induced traumatic brain injury (TBI) is one of the most common injuries to military personnel. Brain tissue compression/tension due to blast-induced cranial deformations and shear waves due to head rotation may generate diffuse micro-damage to
