The data file is a zip file, which is split into 19 files using 'split' command in Mac. The zip file is titled 'ProcessedData.zip'. The zip file contains seven folders and the folders contain processed data used to compute main results and to create all figures in the manuscript. 1) Behavioral confusion matrix 2) ITPC and induced power 3) Phase and power data for classification and mutual information analysis 4) Selected channels for each subject 5) Shuffled ITPC 6) Sound materials 7) Temporal averaged data Each folder (except Sound materials) contains data files of 15 subjects. The subject is indicated by ‘sub#’ in the filename. In each folder, there is a ‘readme’ text file that illustrates data information. All the datasets are of matlab format and could be processed in MATLAB. Some datasets are formatted in fieldtrip data structure and the information about the data structure can be found here: www.fieldtriptoolbox.org Further information on data processing can be found in the Method section of the manuscript. The raw data files and the denoised data files can be required by contacting Xiangbin Teng, [email protected]

Stimuli and behavioral results.

<p>(a) Cochleograms of 3 stimulus types. A Gammatone filterbank of 64 banks was used to decompose the stimuli. The prior distributions of segment duration for the 3 stimuli are shown on the right. (b) Behavioral performance. The blue, gray, and red lines show d-prime values for <i>θ</i>, <i>α</i>, and <i>γ</i> sounds across different signal-to-noise ratios (SNRs), respectively. The 3 separately plotted results at the top-right corner are d-prime values in clean stimulus conditions. Error bars: ±1 standard error of the mean. Data are deposited in the Dryad repository: <a href="http://dx.doi.org/10.5061/dryad.f357r" target="_blank">http://dx.doi.org/10.5061/dryad.f357r</a> [<a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.2000812#pbio.2000812.ref121" target="_blank">121</a>].</p

Classification results.

<p>(a) Confusion matrices for phase-based and power-based classifications. “Stimulus label” represents the actual stimulus type and “classified label” represents the classified bin. Color bar codes the percentage of trials classified into each bin. (b) Classification performance for each sound using phase and power. Phase-based classification performs significantly better than power-based classification. The blue, gray, and red bars represent <i>θ</i>, <i>α</i>, and <i>γ</i> sounds, respectively. (c) Frequency band contributions to phase-based classification of each sound. “N” indicates classification without the given frequency band; “Y” indicates classification with the given frequency band. Phase in the theta band improves performance for classifying all stimuli and phase in the gamma band contributes to classifying γ sound. The color scheme is as in (b). The error bars represent ±1 standard error of the mean.

<i>Z</i>-scores of intertrial phase coherence (zITC) to 3 clean stimuli and their response topographies.

<p>(a) Top panel, spectra of zITC for <i>θ</i>, <i>α</i>, and <i>γ</i> sounds. The dashed line (<i>z</i>-score of 1.64) is equivalent to an alpha level of 0.05 (1-tailed, corrected). The shaded areas represent ±1 standard error of the mean. The bottom panel shows zITC for <i>θ</i>, <i>α</i>, and <i>γ</i> sounds in 4 frequency bands, theta (4–7 Hz), alpha (8–12 Hz), beta (13–30 Hz), and gamma (31–45 Hz). The color scheme of blue, gray, and red in both panels represents zITC of <i>θ</i>, <i>α</i>, and <i>γ</i> sounds, respectively. The error bars represent ±1 standard error of the mean. (b) Topographies of zITC for each sound at each frequency band. Auditory response patterns (compared to, for example, classic evoked M100 responses) are observed clearly in the theta band for <i>θ</i> sounds as well as for the <i>α</i> and <i>γ</i> sounds. In the gamma band, the topographies show the auditory response pattern only for the <i>γ</i> sound. No clear pattern is observed in other frequency bands.

Time-frequency analyses of evoked power.

<p>Evoked power responses to <i>θ</i>, <i>α</i>, and <i>γ</i> sounds, respectively. The vertical dashed lines indicate the onset of the auditory stimuli. The dashed boxes in the panels mark the frequency bands of evoked power responses corresponding to the stimulus modulation rates. <i>θ</i> sounds evoke power increase in the theta band and <i>γ</i> sounds in the gamma band.
