性爱的最高境界莫过于达到性高潮，可是据统计，美国大约有四分之一的妇女难以达到性高潮；科学家认为，如果能找到女人高潮之谜，或许可以拯救这些无法达到高潮的妇女。$ y1 v1 X E9 Y+ o O

这项研究邀请多名女性自愿者参与，在她们躺在核磁共振扫描器时，并与性伴侣调情到性高潮，而从脑部扫描出的照片显示，当她们达到高潮时，脑部的「眼窝额皮质」就会呈现关闭。: @8 _5 o5 B) F

研究人员乔治艾迪斯(Janniko Georgiadis)指出，当人们描述高潮的感觉，多以「失去控制」来形容，从电脑扫描照片来看，性高潮会改变人的意识状态。 研究人员认为，也许让性冷感的妇女观察自己脑部变化，再经由一些「训练」，控制脑部的「眼窝额皮质」放轻松，就能享受未曾经历的快感。 9 F( A, @3 q% Y$ ]' s; _9 D
