Abstract
Boly et al. (Reports, 13 May 2011, p. 858) investigated cortical connectivity patterns in patients suffering from a disorder of consciousness, using electroencephalography in an auditory oddball paradigm. We point to several inconsistencies in their data, including a failure to replicate the classical mismatch negativity. Data quality, source reconstruction, and statistics would need to be improved to support their conclusions.
摘要
博利等人（2011 年 5 月 13 日，第 858 页）采用听觉Oddball 范式的脑电图技术，对意识障碍患者的皮质连接模式进行了研究。我们发现他们的数据存在多个不一致之处，包括未能复制经典的失匹配负波。要支持他们的结论，需要提高数据质量、源重建和统计学方法。
