Abstract：Source memory has important functions in ours lives. Functional magnetic resonance imaging（fMRI）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 fMRI，should be integrated to separate specific brain regions in different stages of source memory.
