Abstract(in Japanese) (See Japanese page)
Abstract(in English) Episodic memory retrieval refers to the retrieval of personally experienced past events.Electrophysiological(e.g., ERPs)and hemodynamic(e.g., PET, fMRI)measures of brain activity indicate that this process involves primarily medial temporal and front alactivity.Medial temporal activity seem to reflect retrieval of stored information(retrieval success)whereas anterior frontal activity seems related to the maintenance of the mental set of episodic retrieval(retrieval model).A combined PET/ERP study indicated that medial temporal activity is brief and item-related while frontal is continuous and task-related.Medial temporal activity may underlie retrieval confidence and occurs also during false recognition.Frontal function is critical for context retrieval and is more sensitive to aging and brain damage than medial temporal function.
