Underlying mechanisms of information integration via interplay of Multiple scale neuronal oscillators

为了研究情景记忆中动态出现的皮层网络的潜在机制，我们同时测量了fMRI和EEG。这项任务是记忆物体和地点信息的关联，这些信息将在海马体中处理。结果表明，当脑电图振荡出现在头皮前部-中部时，内侧前额叶皮层、额叶视野、视觉皮层和海马旁位区形成了一个成功记忆保留的皮层网络。此外，我们开发了一种结合同时记录的功能磁共振成像和脑电图的方法。该方法能够利用功能磁共振成像的空间和时间精度来识别皮层脑电活动。

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.
