Sub-Concussive Blows Lead to Changes in Event-Realted Potentials Associated with Visual Sensory Gating: An EEG Study

Visual sensory gating, the ability to gate out competing visual stimuli and gate in relevant novel stimuli, was shown to be lacking in participants with self-reported histories of head blows. These participants showed a near absence of P50 and P200 ERP’s which were used as a proxy for visual gating.
