摘　　要：视觉事件相关电位(event-related potential,ERP)是利用不同范式的视觉刺激,从检测并记录神经电生理反应的角度客观反映大脑对刺激的认知加工过程的电生理技术,其内源性成分与高级心理活动有着密切联系。本文介绍了视觉ERP主要内源性成分(视觉失匹配负波、N200、P300)的特征,综述了其在颅脑损伤后遗症和视功能客观评价中的相关研究进展,展望了视觉ERP在法医学领域的应用前景。Visual event-related potential(ERP)is an electrophysiological technique that objectively reflects the cognitive processing of stimulus from the perspective of detecting and recording neural electrophysiology responses using different paradigms of visual stimuli.Its endogenous components are closely related to advanced psychological activities.This article introduces the characteristics of main endogenous components including visual mismatch negativity(vMMN),N200 and P300,reviews the research progress of visual ERP in the sequelae of brain injury and objective evaluation of visual function,and prospects the application prospect of visual ERP in the field of forensic medicine.
