rawData.zip

<b>rawData.zip</b><br> <br> The data were recorded using BCI2000 software (see https://www.bci2000.org/mediawiki/index.php/Technical_Reference:BCI2000_File_Format). Each folder corresponds to one experimental session (day) and named by 2-letter participant's code and 3-digit session number. Files within each session correspond to "runs" (...R00) - continuous multichannel EEG recordings comprised of trials (epochs) and intertrial intervals. <br> Epochs corresponding to experimental cues marked up by "StimulusCode" variable. Stimulus code "1" refers to motor imagery of some kind and stimulus code "2" - to visual attention to an abstract picture (non-motor condition, reference). Stimulus code "0" refers to interstimulus intervals (blank screen). <b>recData.mat</b> - is matlab-formatted table, containing a description of files, specifying the type of motor imagery used (FL/FR - left/right hand fingers tap imagery, SL/SR - left/right arm circumduction imagery, TR/TR_video - right hand thumb swipe imagery without/with video instruction present) and feedback condition (presented/not presented). <br>Columns 9 and 10 - indicies of epochs corresponding to imagery (9) and non-motor task (10)<br>The last 5 columns represent the strength of event-related desynchronization of EEG sensorimotor rhythms during the motor imagery compared to non-motor task. (m1 - at the strongest source, m2 - mean of the two strongest sources ... m5 - mean of the five strongest sources).<br>
