这篇综述是基于人类颅内记录（颅内脑电图，iEEG）的技术特点和已经产生的大量结果，试图突出其在人脑制图中的价值。详细介绍了iEEG记录的优点和局限性，并对单极和双极记录的空间和时间分辨率进行了估计。通过回顾在患者执行认知任务时观察到的脑电图的影响，讨论脑电图研究对人类大脑制图的一般领域的贡献。这些影响的范围从产生定位良好的诱发电位到形成分布的大脑结构之间的大规模相互作用，特别是通过远程同步。根据发现与认知相关的神经活动的时空模式的复杂程度，介绍了一个框架来组织这些脑电图研究。这篇综述强调了iEEG对大规模相互作用研究的价值，并详细描述了已经解决这一点的少数研究。(C) 2004 Elsevier Ltd.版权所有。
This review is an attempt to highlight the value of human intracranial recordings (intracranial electro-encephalography, iEEG) for human brain mapping, based on their technical characteristics and based on the corpus of results they have already yielded. The advantages and limitations of iEEG recordings are introduced in detail, with an estimation of their spatial and temporal resolution for both monopolar and bipolar recordings. The contribution of iEEG studies to the general field of human brain mapping is discussed through a review of the effects observed in the iEEG while patients perform cognitive tasks. Those effects range from the generation of well-localized evoked potentials to the formation of large-scale interactions between distributed brain structures, via long-range synchrony in particular. A framework is introduced to organize those iEEG studies according to the level of complexity of the spatio-temporal patterns of neural activity found to correlate with cognition. This review emphasizes the value of iEEG for the study of large-scale interactions, and describes in detail the few studies that have already addressed this point. (C) 2004 Elsevier Ltd.
