Multiday motor imagery with and without feedback

rawData.zip

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.

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).

recData.mat - 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).

Columns 9 and 10 - indicies of epochs corresponding to imagery (9) and non-motor task (10)

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).
