Event-related potential assessment of information processing after closed head injury.

摘要: We evaluated alterations in information processing after closed head injury as a function of task demands and stimulus modality- Visual auditory discrimination tasks were administered to 1 survivors 16 matched healthy controls. In tasks, compared with controls, the had smaller N100s, rind later N200s, more posterior scalp distribution N200, longer P300 response latencies. Auditory N200 correlated highly duration unconsciousness. contrast, visual only reduced differentiated groups. Our results indicate that stimuli, including perception features evaluation categorization may be impaired heat trauma. sensory spared, but higher-order involved classification compromised.
