EEG Data for: "Cortical oscillations and entrainment in speech processing during working memory load"

<p>This repository contains EEG and audio data used and described in:</p> <p><strong>Hjortkj&aelig;r, J, M&auml;rcher-R&oslash;rsted, J, Fuglsang, SA, Dau, T (2018). Cortical oscillations and entrainment in speech processing during working memory load. European Journal of Neuroscience.&nbsp;</strong><strong>doi</strong><strong>:10.1111/ejn.13855</strong></p> <p>Please cite this article when using the data</p> <p>&nbsp;</p> <p>The MAT-files contain the aligned EEG and audio data for each subject (N=22). The envelopes of the speech audio (without noise) have been extracted as described in the paper. Each file (data_N.mat) contains a Matlab struct in the format of the Fieldtrip toolbox containing the following fields:</p> <p>&nbsp;</p> <p>data.trial:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;EEG and audio data for all 40 trials [channels x timepoints]</p> <ul> <li>channels 1-64: scalp EEG</li> <li>channel 65: left mastoid electrode</li> <li>channel 66: right mastoid electrode</li> <li>channel 67: horizontal EOG</li> <li>channel 68: vertical EOG for left eye</li> <li>channel 69: vertical EOG for right eye</li> <li>channel 70: audio envelopes</li> </ul> <p>data.trialinfo:&nbsp; &nbsp; &nbsp;Experimental condition in each trial</p> <ul> <li>1 = low noise, 1-back</li> <li>2 = low noise, 2-back</li> <li>3 = high noise, 1-back</li> <li>4 = high noise, 2-back</li> </ul> <p>data.time:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Sample indices for each trial in seconds</p> <p>data.label:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Name of each channel in data.trial</p> <p>data.fsample:&nbsp; &nbsp; EEG/audio sampling rate in Hz (128)</p>
