How Traumatic Brain Injuries affect Speech:Translating Principles of Neural Plasticity Into Research on Speech Motor Control Recovery and Rehabilitation:
The purpose of this study is discriminate between principles of plasticity and speech motor coordination to improve neurological rehabilitation. The study defined neural plasticity as the ability of the central nervous system to change and adapt in response to environmental cues, experiences, behavior, injury, or disease and can result in a change in function within the brain. Changes can include changes in intracortical microcircuitry, altering the topography of cortical maps. Changes can produce latency in connections or dendrite sprouting. Following a Traumatic Brain injury further damage to cortical areas if there is not a period of retraining following the injury. The training should focus on the areas of the brain which are damaged. Recovery is greatest in the first three months following the injury. The study found that speech movements have greater potential for being retained than for non-speech movements. Sources: Ludlow, C.
