Nunez 和 Srinivasan (2010) 在他们最近的社论中断言，伽玛带活动和颅内记录近年来受到了过多的关注。我们同意，必须在所有可能的尺度和多个频带上检查大脑动力学，并且将我们对大脑动力学的理解仅限于颅内记录或更高频率的内容是愚蠢的。然而，作者提出的一些观点需要进一步考虑。强调多少才算“太多”？ PubMed 对 2007 年以来出版物的检索显示，各频段的引用分布大致遵循静息头皮脑电图中相应的功率分布（见图 1），有 1,356 篇论文引用了 α 或 mu 节律，而 790 篇论文引用了伽马带活动，只有 60 篇提到了高伽马活动。与此同时，自 2007 年以来，有 14,992 篇出版物引用了 EEG 或 MEG，而只有 337 篇出版物提到了颅内 EEG。 1
In their recent editorial, Nunez and Srinivasan (2010) assert that gamma band activity and intracranial recordings have been receiving an inordinate amount of attention in recent years. We agree that brain dynamics must be examined at all possible scales and across several frequency bands, and that it would be foolish to restrict our understanding of brain dynamics exclusively to intracranial recordings or higher frequency content. However, a number of points raised by the authors require further consideration. How much emphasis is ‘‘too much’’? A PubMed search of publications since 2007 reveals that the distribution of citations across frequency bands roughly follow their corresponding power distribution in the resting scalp EEG (see Fig. 1), with 1,356 papers citing alpha or mu rhythms, while 790 cite gamma band activity and only 60 mention high gamma activity. Meanwhile, since 2007, 14,992 publications have cited EEG or MEG, while only 337 mention intracranial EEG. 1
