| 33 | Electrode locations were chosen for relevance to movement/ motion intention. C3, Cz, and C4 are associated with sensorimotor integration. F3 and F4 are associated with motor planning. These are the central nodes. Fp1 and Fp2 are associated with attention and judgement, while Fz is associated with working memory. |

| 35 | Data collected was as follows: |
| 36 | |
| 37 | 5 samples rest (10 sec each) |
| 38 | 10 samples up |
| 39 | 10 samples down |
| 40 | 10 samples right |
| 41 | 10 samples left |
| 42 | |
| 43 | (up, down, left, right represent direction of imagined motion; each sample includes 3 sec prep and 3 sec imagined movement) |

| 47 | Data analysis (for EEG/ BCI data) is being done through EEGLAB and BCILAB toolboxes for MATLAB (from the [http://sccn.ucsd.edu/ Scwartz Center for Computational Neuroscience]). Sample data was initially used to create channel spectra maps (and other data visualizations) using the EEGLAB interface. |
