目的 探讨不同内容视觉性刺激诱发成年男性性唤起时事件相关电位特征的差异.方法 采用内隐情绪诱发任务和改进后的双选择Oddball范式,利用事件相关电位技术,记录男-女色情图片、男性裸体图片与女性裸体图片诱发15名健康成年男性性唤起时脑电生理变化的差异.结果 三类性图片诱发额中央区(Fz) N2波幅、顶中央区(Pz)P3波幅[分别为:男-女性活动图片(2.32±1.70) μ V、(16.62±2.16) μV;男性裸体图片(1.58±1.33) μV、(15.82±1.64) μV;女性裸体图片(1.23±1.47) μV、(14.54±2.00) μV]均差异无统计学意义(均P＞0.05)；但三类性图片诱发N2、P3波幅均显著大于中性人物图片[(-6.01±1.35)μV、(11.36±1.81)μV](均P＜0.05)；三类性图片诱发中央区(Cz)的PSW波幅差异具有统计学意义,其中男-女性活动图片[(12.59±1.13)μV]诱发的PSW波幅显著大于女性裸体图片[(10.38±0.76) μV]和男性裸体图片[(8.80±0.89)μV],(均P＜0.05),但女性裸体图片和男性裸体图片诱发的PSW波幅差异无统计学意义(P=0.25).结论 高度暴露的男-女性活动图片诱发成年男性最强的性唤起及消耗最多的注意资源,性唤起维持时间也最长.

Objective To observe the differences in event related potential(ERP) during sexual arousal elicited by different types of sexual picture in adult men.Methods An implicitly emotional task and a modified oddball paradigm were used.The differences were recorded in EEG with ERP when sexual arousal was induced by heterosexual couple erotic picture,male erotic picture and female erotic picture in fifteen health men.Results The amplitudes of N2 at Fz and P3 at Pz induced by male-female erotic picture ((2.32 ± 1.70) μV,(16.62 ± 2.16) μV),male erotic picture ((1.58 ± 1.33) μ V,(15.82 ± 1.64)μV) and female erotic picture ((1.23 ± 1.47)μV,(14.54 ± 2.00)μV)were not significant differences (P ＞ 0.05).But the amplitudes of N2 and P3 elicited by neutral human picture((-6.01 ± 1.35)μV,(11.36 ± 1.81) μV) were smaller than each type erotic picture (P ＜ 0.05).There was statistical significance in PSW at Cz elicited by different types of erotic picture.The PSW elicited by male-female erotic picture((12.59 ± 1.13)μV) was significantly higher than female erotic picture((10.38 ±0.76) μV) and male erotic picture((8.80 ±0.89) μV) (P＜0.05).However,there was no significant difference in PSW component between male erotic picture and female erotic picture.Conclusion The level of sexual arousal elicited by explicit heterosexual couple erotic pictures is highest and the attention also maintains longest in heterosexual male.
