目的探讨用单通道脑电检测连续语音的皮层反应。特别是，使用互相关方法和从时间响应函数（TRF）中提取的参数比较检测率和时间。DesignEEG从32个通道记录，同时呈现25分钟的连续英语语音。检测参数为语音和EEG之间的互相关（XCOR）、TRF滤波器的峰值和功率（TRF-peak and TRF-power）以及预测TRF和真实EEG之间的相关性（TRF-COR）。使用自助分析确定响应的统计学显著性。不同的电极配置进行了比较：使用单通道Cz或Fz，或选择通道的最高correlation value.Study sampleSeventeen母语为英语的科目与轻度至中度hearing loss.ResultsSignificant皮质反应检测到所有科目在Fz通道与XCOR和TRF-COR。与TRF参数（最佳TRF-COR，平均值= 6.4 min）相比，XCOR（平均值= 4.8 min）的检测时间较短，从XCOR到TRF峰值和TRF功率的时间差异显著。分析多个EEG通道和测试通道与包络和EEG之间的最高相关性降低检测灵敏度相比，FZ单独.ConclusionsCortical连续语音的反应，可以检测到从一个单一的通道与记录时间，可能是适合于临床应用。
ObjectiveTo explore the detection of cortical responses to continuous speech using a single EEG channel. Particularly, to compare detection rates and times using a cross-correlation approach and parameters extracted from the temporal response function (TRF).DesignEEG from 32-channels were recorded whilst presenting 25-min continuous English speech. Detection parameters were cross-correlation between speech and EEG (XCOR), peak value and power of the TRF filter (TRF-peak and TRF-power), and correlation between predicted TRF and true EEG (TRF-COR). A bootstrap analysis was used to determine response statistical significance. Different electrode configurations were compared: Using single channels Cz or Fz, or selecting channels with the highest correlation value.Study sampleSeventeen native English-speaking subjects with mild-to-moderate hearing loss.ResultsSignificant cortical responses were detected from all subjects at Fz channel with XCOR and TRF-COR. Lower detection time was seen for XCOR (mean = 4.8 min) over TRF parameters (best TRF-COR, mean = 6.4 min), with significant time differences from XCOR to TRF-peak and TRF-power. Analysing multiple EEG channels and testing channels with the highest correlation between envelope and EEG reduced detection sensitivity compared to Fz alone.ConclusionsCortical responses to continuous speech can be detected from a single channel with recording times that may be suitable for clinical application.
