| Research Abstract |
To investigate the underlying mechanisms of the cortical networks which dynamically emerge for the episodic memory, we measured the simultaneous fMRI and EEG. The task was the memory for the association of objects and places information, which would be processed in the hippocampus. The results showed that the medial prefrontal cortex, the frontal eye field, the visual cortex and the parahippocampal place area emerge a cortical network for the successful memory retention, when the theta EEG oscillation appeared on the front-central scalp sites. Furthermore, we developed a method for combining the simultaneously recorded fMRI and EEG. This method enables to identifying the cortical EEG activity with the fMRI spatial and EEG temporal precisions.
