Preliminary Work-Technical University Graz
Methods
Subjects and Signal Source
- Healthy subjects
- EEG electrodes
- 4 - 56 electrodes
- Electrodes placed for research purposes over frontal, central, and
parietal areas
- 2 to 8 identical data collection sessions
Experimental Paradigm
- Each session contained 4 runs of 40 trials each
- Trial started when a fixation cross appeared
- The fixation cross was overlaid with an arrow (pointing left, right or
down) for 1.25 seconds
- Subject responded by imagining lifting left/right hand or foot
- Feedback provided during imagination
EEG Analysis Methods
- Band Power and Linear Discriminant Analysis (LDA)
- Adaptive Autoregressive Parameters and LDA
- Common Spatial Patterns and LDA
