| Research Abstract |
The functions of various brain areas on the encoding and retrieval of episodic memory have been studied intensely, yet the specific contribution of each brain area has not been elucidated. The purpose of the present study was to identify neural networks that support event memory itself, temporal context memory, spatial context memory, and source memory. For this purpose, we employed both neuroimaging and neuropsychological studies. The results showed (1)the influence of prefrontal activity on medial temporal lobe activity during the retrieval of episodic memory,(2)the crucial role of the medial temporal lobe in the retrieval of source memory, and (3)the differential roles of subregions within the medial temporal lobe in episodic memory.
