Overview

With increased awareness of the long-term effects of traumatic brain injury on cognition, many researchers are curious as to what can be done to enhance recovery. Here, researchers used SMART™ training techniques and measured the cortical thickness in 60 individuals with chronic TBI. Their findings indicate that cognitive training can induce brain plasticity that continues throughout the chronic phases of TBI.
