We examined the fMRI prefrontal activities associated with two forms of episodic retrieval, i.e., retrieval for which complex cognitive activities are required and one for which simple recognition is enough. The two types of retrieval activated overlapping and separate brain areas. The former included the bilateral parahippocampal, cerebellar hemispheres, medial and inferior occipital, and right prefrontal and left inferior temporal areas, while the left frontal area was activated only with the complex retrieval task. These findings suggest differential involvement of each prefrontal area for these two types of retrieval. The right prefrontal area is primarily related to simple or basic retrieval of episodic items such as a single word or picture, while the left to complex or systematic retrieval such as integration among episodic items.
