Scale‐free functional brain dynamics during recovery from sport‐related concussion

Human Brain Mapping, 2020
Studies using blood‐oxygenation‐level‐dependent functional magnetic resonance imaging (BOLD fMRI) have characterized how the resting brain is affected by concussion. The literature to date, however, has largely focused on measuring changes in the spatial

A prospective pilot investigation of brain volume, white matter hyperintensities and haemorrhagic lesions after mild traumatic brain injury

Frontiers in Neurology, 2016
Traumatic brain injury (TBI) is among the most common neurological disorders. Haemorrhagic lesions and white matter hyperintensities (WMH) are radiological features associated with moderate and severe traumatic brain injury TBI.

A common neural signature of brain injury in concussion and subconcussion

Science Advances, 2019
Clinically silent brain injury in contact sports athletes can be detected by noninvasive MRI. The midbrain is biomechanically susceptible to force loading from repetitive subconcussive head impacts (RSHI), is a site of tauopathy in chronic traumatic ...
