Ethics
Every experiment involving human participants has been carried out following a protocol approved by the Institutional Review Board of Carnegie Mellon University. Each participant gave informed written consent. (Quoted verbatim from the primary publication’s Ethics statement: Wang, H., Zhang, Y., Karrenbach, M., Ding, Y., & He, B. (2026). Sensory-guided human-machine joint learning accelerates the acquisition of motor imagery brain computer interface control. Nature Communications, 17, 6177. https://doi.org/10.1038/s41467-026-75435-5. Participants were recruited from the Pittsburgh area and compensated $15/hour; informed consent followed the World Medical Association’s Declaration of Helsinki.)
Participants
Number of subjects: 39 Health status: healthy BCI experience: naive
Experimental Protocol
Paradigm: imagery Task type: online 1D and 2D cursor control Number of classes: 4 Class labels: left_hand, right_hand, hands, rest Trial duration: 5.0 s Tasks: left hand imagery, right hand imagery, bilateral hand imagery, rest Study design: One longitudinal MI-BCI study release with 39 unique participants. The primary randomized experiment included 31 participants: joint learning (n=15), BCI2000 control (n=8), and tactile control (n=8). A separately recruited EEGNet-control cohort added 8 participants. Feedback type: visual cursor feedback, with cohort-specific tactile guidance, EEGNet adaptation, or fixed BCI2000 decoding Stimulus type: visual cursor and directional cue Stimulus modalities: visual, tactile Primary modality: visual Synchronicity: synchronous Mode: online Training/test split: True Stimulus presentation: SoftwareName=BCI2000

Paradigm-Specific Parameters
Detected paradigm: motor_imagery Imagery tasks: left_hand, right_hand, hands, rest Imagery duration: 5.0 s
Data Structure
Trials: varies by run and subject Blocks per session: 6 Trials context: Each regular session contains six runs; run0 is a separate initial BCI2000 baseline. Subjects completed 4, 6, or 8 regular sessions.
Preprocessing
Data state: trial-segmented Preprocessing applied: True Steps: trial segmentation, auxiliary-channel exclusion, per-trial temporal centering in the MOABB reconstruction Notch filter: 60.0 Hz Notes: The release contains 62 selected EEG channels and states that no additional filtering or downsampling was applied. Runs use either fixed-length EEGNet trials or variable-length BCI2000 trials.
Signal Processing
Classifiers: weighted EEGNet, EEGNet, BCI2000 linear classifier Feature extraction: EEGNet, autoregressive spectral features Frequency bands: online_EEGNet=[4.0, 40.0] Hz Spatial filters: CSP-based initial sample weighting

Examples
>>> from eegdash.dataset import NM000335 >>> dataset = NM000335(cache_dir="./data") >>> recording = dataset[0] >>> raw = recording.load()
- __init__(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#
- save(path: str, overwrite: bool = False, offset: int = 0)[source]#
Save datasets to files by creating one subdirectory for each dataset:
path/ 0/ 0-raw.fif | 0-epo.fif description.json raw_preproc_kwargs.json (if raws were preprocessed) window_kwargs.json (if this is a windowed dataset) window_preproc_kwargs.json (if windows were preprocessed) target_name.json (if target_name is not None and dataset is raw) 1/ 1-raw.fif | 1-epo.fif description.json raw_preproc_kwargs.json (if raws were preprocessed) window_kwargs.json (if this is a windowed dataset) window_preproc_kwargs.json (if windows were preprocessed) target_name.json (if target_name is not None and dataset is raw)
- Parameters:
path (str) –
- Directory in which subdirectories are created to store
-raw.fif | -epo.fif and .json files to.
overwrite (bool) – Whether to delete old subdirectories that will be saved to in this call.
offset (int) – If provided, the integer is added to the id of the dataset in the concat. This is useful in the setting of very large datasets, where one dataset has to be processed and saved at a time to account for its original position.
