README

Data was collected at the University of Michigan by Steven Peterson in the lab of Daniel Ferris. This study's protocol was approved by the University of Michigan Institutional Review Board and all participants provided written consent.

Each data file includes synchronized 128-channel EEG, lower leg EMG, neck EMG, EOG, and motion capture data. Participants performed four 10-minute, same-day sessions where they either stood or walked at 0.22 m/s on a treadmill-mounted balance beam that was 2.5 cm tall and 12.7 cm wide.

During each session, participants were exposed to sensorimotor perturbations (either virtual-reality-induced visual field rotations or side-to-side waist pulls, lasting 0.5 seconds and 1 second in duration, respectively). Each session involved 150 perturbation events, balanced between rotation/pull directions.

We have included the indices of all good channels for each participant in EEG.etc.good_chans of each .set file (includes non-EEG channel indices). Criteria for determining good/bad EEG channels can be found in our eNeuro publication. EEG.etc also includes the resulting ICA sphere and weight matrices when run on only the EEG channels, along with the selected good IC's that were retained for our analyses.

Dear Dr. Peterson,

Thanks for uploading this dataset. I read in your paper that you've employed a pre-processing procedure to remove bad channels. Could you perhaps upload the list of bad channels for each of these .set files? Thank you again!

Hi Velu,

The indices of all good channels for each participant can be found under EEG.etc.good_chans (includes non-EEG channel indices). The bad channels are the ones with indices not included in EEG.etc.good_chans. I have updated the README to include this information.
