ProjectCerebro — Cho 2017 EEG Motor Imagery Dataset (BCI_Data_new)
Dataset Description
Preprocessed EEG motor imagery epochs from the Cho 2017 dataset (GigaDB 100295), processed through the ProjectCerebro pipeline.
Original paper:
Cho, H., et al. (2017). EEG datasets for motor imagery brain–computer interface. GigaScience, 6(7), 1–8. https://doi.org/10.1093/gigascience/gix034
Dataset Structure
Each row is one 4-second EEG epoch with these columns:
| Column | Type | Description |
|---|---|---|
| epoch_id | string | Unique identifier |
| dataset | string | Always cho2017 |
| subject_id | string | Subject ID (s01–s52) |
| label_code | int | 0=left, 1=right, 2=rest |
| label_name | string | left, right, or rest |
| features | float32[] | Flattened EEG (5 ch × 512 samples = 2560 floats) |
| n_channels | int | 5 |
| n_samples | int | 512 (4s @ 128Hz) |
| channel_names | string[] | [FZ, C3, CZ, C4, PZ] |
| sampling_rate_hz | float | 128.0 |
| filter_version | string | bp_8_30_v1 or bp_4_38_v1 |
| preprocessing_version | string | v1.1.0 |
Preprocessing Pipeline
Stage 1 — ICA artifact removal (infomax + ICLabel)
- 20 ICA components fitted on 1–100 Hz broadband signal
- Eye blink, muscle, line noise components excluded (>0.8 confidence)
- Output: cleaned
.fiffiles
Stage 2 — Epoch extraction & standardization
- 5 common channels selected: FZ, C3, CZ, C4, PZ
- Bandpass filter: 8–30 Hz (primary) or 4–38 Hz (ablation)
- Resampled to 128 Hz
- Epochs: -1s to +3s around trial onset → 512 samples
- Baseline correction: subtract mean of pre-stimulus period
Files
| File | Description |
|---|---|
bp8_30/*.parquet |
Primary filter (8–30 Hz) — motor imagery band |
bp4_38/*.parquet |
Ablation filter (4–38 Hz) — broader band |
