Neural responses to the onset of speech in both the speaking and the listening condition. In each plot, time is relative to the onset of speech at 0ms. Red traces show the mean cortical responses at the corresponding anatomical location across all subjects in the speaking condition. The thick red line is the grand-average over subjects and the flanking thin red lines are the standard error bars. Blue traces show the mean cortical responses in the listening condition. The thick blue line is the grand-average over subjects and the thin blue lines are the standard error bars. Solid boxes surround peaks with a significant magnitude difference between speaking and listening, p< 0.0096, dotted boxes surround peaks with p<0.05. Similarly, solid lines mark significantly different latencies of peaks between speaking and listening, p< 0.0096, and dotted lines mark peaks with p<0.05.
