摘要 目的利用事件相关脑电位(ERP)技术探讨健康成人错误监控功能的特征。方法将62名19~50岁的右利手健康成人作为被试者(男性33名,女性29名),平均年龄(29.6±6.6)岁,平均受教育年限(16.7±2.0)年。应用德国Brain Products公司的ERP记录与分析系统检测被试者前额区(Fz)、中央区(Cz)、左中央区(C3)、右中央区(C4)及顶区(Pz)的错误相关负电位(ERN),对ERN潜伏期和波幅进行统计学分析。结果各脑区头皮记录点均在约50 ms处出现1个负波,ERN波形较稳定。统计学分析结果显示:C3脑区与C4脑区的ERN潜伏期和波幅比较,差异均无统计学意义(P>0.05);在Fz、Cz、Pz 3个脑区,男性组与女性组的ERN潜伏期和波幅比较,差异也无统计学意义(P>0.05);Fz和Cz脑区的ERN波幅与被试者年龄呈显著正相关(r=0.282,P=0.027;r=0.250,P=0.049)。结论健康成人的ERN较稳定、可靠,在神经精神科临床工作中具有一定的推广和应用价值。 目的利用事件相关脑电位(ERP)技术探讨健康成人错误监控功能的特征。方法将62名19~50岁的右利手健康成人作为被试者(男性33名,女性29名),平均年龄(29.6±6.6)岁,平均受教育年限(16.7±2.0)年。应用德国Brain Products公司的ERP记录与分析系统检测被试者前额区(Fz)、中央区(Cz)、左中央区(C3)、右中央区(C4)及顶区(Pz)的错误相关负电位(ERN),对ERN潜伏期和波幅进行统计学分析。结果各脑区头皮记录点均在约50 ms处出现1个负波,ERN波形较稳定。统计学分析结果显示:C3脑区与C4脑区的ERN潜伏期和波幅比较,差异均无统计学意义(P>0.05);在Fz、Cz、Pz 3个脑区,男性组与女性组的ERN潜伏期和波幅比较,差异也无统计学意义(P>0.05);Fz和Cz脑区的ERN波幅与被试者年龄呈显著正相关(r=0.282,P=0.027;r=0.250,P=0.049)。结论健康成人的ERN较稳定、可靠,在神经精神科临床工作中具有一定的推广和应用价值。
