闪光灯记忆（FM）是一种生动、持久的记忆，它记录了一个人如何了解到一件令人惊讶、震惊的事情。因此，调频涉及对事件信息来源的记忆，而不是对事件本身的记忆。然而，调频涉及的大脑区域尚不确定。虽然内侧颞叶/间脑（MTL/D）损伤损害了内容或项目记忆，额叶（FL）损伤与源记忆受损有关。因此，人们会期望FM应该依赖于FLs，尽管最近的两份报告并不支持这一观点。在当前的研究中，我们检查了MT/D患者、FL患者和健康受试者对911事件的记忆，以及对该信息来源的记忆。在6个月的保留间隔后，只有MTL/D患者对事件本身的长期记忆受损。另一方面，FL患者表现出源记忆的选择性缺陷，尽管他们对目标事件的记忆没有受损。MTL/D和FL结构在闪光灯事件记忆中起着不同的作用。
A flashbulb memory (FM) is a vivid, enduring memory for how one learned about a surprising, shocking event. It thus involves memory for the source of event information, as opposed to memory for the event itself Which brain regions are involved in FM, however, is uncertain. Although medial temporal lobe/diencephalic (MTL/D) damage impairs content or item memory, frontal lobe (FL) damage has been associated with impaired source memory. One would therefore expect that FM should depend on the FLs, although two recent reports do not support this idea. In the current study, we examined memory for the events of September 11th, and memory for the source of that information, in MT/D patients, FL patients, and healthy subjects. Only the MTL/D patients were impaired in long-term memory for the event itself measured after a 6 month retention interval. The FL patients, on the other hand, showed a selective deficit in source memory, although their memory for the target event was unimpaired. MTL/D and FL structures appear to play different roles in memory for flashbulb events.
