Mild Traumatic Brain Injuries and Their Implications on Changes in Event Related Potentials: A look into Visual Gating (P50)
type: CreativeWork
description: Concussions are a prevalent injury that affect a wide range of individuals. Commonly seen amongst individuals who play contact sports, there are many underlying factors that doctors and clinicians have yet to understand which include properties such as proper diagnosis standards or lasting impacts. In this study, we look at those impacts by using electroencephalographic (EEG) measures to study the changes in event related potentials (ERPs) associated with sensory gating and how this cognitive property is affected in those who have a self-reported concussion. Here we show that a visual attention and gating mechanism exists in both populations (control and concussed) as seen by the P50 ERP after the presentation of our visual stimulus, which is dependent on the Order the stimulus is presented (1st or 2nd). Our findings show that those who have suffered a concussion show a difference in the ability to sensory gate which is prevalent by the differences in ERPs between the two groups.
