Concussion could alter transmission of information within the brain

Researchers from New York University (NY, USA) have discovered a correlation between cross-hemispheric cerebral activity and a delayed response time in concussion patients. The study, presented recently at the Radiological Society of North America Annual Meeting (1–6 December, Chicago, IL, USA), suggests that damage from concussion may alter the way information is transmitted between the two halves of the brain. Previous research has demonstrated that mild traumatic brain injury can cause damage to the corpus callosum. Until now, very little has been known about the effect this has on cognitive function. This study involved 36 patients with recent concussion and...
