(a) Electrode coverage for subject 1. The spatial scale of the grid is indicated in the lower box. Distance is measured along an anterior-posterior line, along the Sylvian fissure, with anatomical reference point of the ventral-most aspect of the central sulcus (position=0). (b) Average high-gamma analytic amplitude (AA) response to words and pseudowords across all electrodes (combined across all subjects). Neural responses to words (red) and pseudowords (blue; shading indicates 95% confidence intervals around the mean at each time point) show prolonged differences, with generally greater responses to pseudowords (black bar; bootstrap p < 0.05). Lower box plots show stimulus length for words and pseudowords, which are not significantly different (p = 0.148). (c) Timing of the peak of neural responses to words and pseudowords in all electrodes, in all subjects, across the anterior-posterior span of the temporal lobe.
