摘　　要：来源记忆在生活中发挥重要作用。功能磁共振成像(functional magnetic resonance imaging,f MRI)研究发现,海马在来源记忆的编码和提取、前额叶在来源记忆的提取监控、顶叶皮层在来源记忆成功提取阶段起着重要作用。事件相关电位(event-related potential,ERP)研究中新发现后期负成分(late posterior negativity,LPN)的新异效应,与来源提取有关。未来研究应综合运用实时动态f MRI等多种技术,分离来源记忆不同阶段的特定脑区。Source memory has important functions in ours lives. Functional magnetic resonance imaging（f MRI）studies have found that hippocampus plays an important role in encoding and retrieval phase of source memory,prefrontal cortex in retrieval monitoring of source memory,and parietal cortex in successful retrieval phase of source memory. And event-related potential（ERP） studies have recently discovered a novel effect called ＂late posterior negativity＂（LPN）,which is related to source retrieval. In future,various technologies,especially real-time f MRI,should be integrated to separate specific brain regions in different stages of source memory.
