Recording

The data was recorded with the BrainAmp DC amplifier and the Brainvision Recorder software (Brainproducts, Munich, Germany). In the Download section you will find the raw, original data format. It is convertable via matlab using biosig (biosig.sourceforge.net/) or eeglab (www.sccn.ucsd.edu/eeglab/).

The data was recorded in two equivalent experimental blocks from 36 subjects. The recordings from all subjects contain data of two equivalent experimental blocks.

All recordings contain 32 EEG channels, two bipolar EOG channels (horizontal and vertical) for tracking class-correlated eye-movements, and  two bipolar EMG channels (left forearm and right forearm) for tracking task-correlated hand movements. No filters were applied during recording and the sampling frequency was 1000 Hz. For details on channel number, position and scale see the following list:
