Electrophysiological white matter dysfunction and association with neurobehavioral deficits following low-level primary blast trauma

► We examine behavioral and electrophysiological outcome following subclinical primary blast exposure in rats. ► Low level primary blast results in increased anxiety and stress-related behavior. ► We observed impairment in unmyelinated and myelinated electrophysiology in the corpus callosum up to 14 days post-injury. ► We demonstrate a loss in interaction between ankyrin G and alphaII-spectrin following low level blast exposure.
