Mobile brain/body imaging (MoBI) during sensorimotor balance perturbations

EEG, EMG, EOG, and sacrum/head position data from 30 participants during sensorimotor balance perturbations. Data is formatted as an EEGLAB .set file. All data streams are synchronized and can be found in the EEG.data section. The order of electrodes is: EEG (#1-128), neck EMG (#129-130), EOG (#131-133), lower leg EMG (#134-141), body motion markers (#142-147), and load cells (#148-149). Digitized electrode locations are included for electrodes 1-133.Neck EMG channel labels: left neck EMG (#129), right neck (#130).EOG channel labels: electrode right of right eye (#131), electrode left of left eye (#132), electrode above left eye (#133).Lower leg EMG electrode labels: LTA (left tibialis anterior), LSOL (left soleus), LMG (left medial gastrocnemius), LPL (left peroneus longus), RTA (right tibialis anterior), RSOL (right soleus), RMG (right medial gastrocnemius), RPL (right peroneus longus).Motion capture marker labels: SACR (sacrum), HEAD (head). Directions: x (mediolateral), y (anterior/posterior), z (superior/inferior). Larger values are in the left, posterior, and superior directions for x, y, and z, respectively.Load cell labels: LoadCell_l (left side), LoadCell_r (right side). These were used to determine the onset timing and force applied during the pull perturbations.Units: Electrodes #1-133 are in uV, #134-141 are in mV, #142-147 are in mm, and #148-149 are in N.
