About This Dataset#

Delineating neural contributions to EEG-based speech decoding

Overview

128-channel EEG recordings during speech production tasks. Participants produced one of 5 color words (green, magenta, orange, violet, yellow) under three speech conditions: overt, minimally overt, and covert. Each trial consists of 5 repetitions of the same word (1.25 sec per repetition).

Delineating neural contributions to EEG-based speech decoding

Overview

128-channel EEG recordings during speech production tasks. Participants produced one of 5 color words (green, magenta, orange, violet, yellow) under three speech conditions: overt, minimally overt, and covert. Each trial consists of 5 repetitions of the same word (1.25 sec per repetition).

Channel layout (139 channels total)

  • Channels 1-128: EEG

  • Channels 129-130: DISPLAY (bipolar pair, misc)

  • Channels 131-132: MIC (bipolar pair, misc)

  • Channels 133-134: EOG (bipolar pair)

  • Channels 135-136: EMG upper orbicularis oris (bipolar pair)

  • Channels 137-138: EMG lower orbicularis oris (bipolar pair)

  • Channel 139: TRIGGER (marks trial onsets)

Session types

  • calibration: Offline data collection for decoder training

  • online: Real-time decoding with trained decoder

Preprocessing note

The EEG channels were recorded with a 10x preamp gain. Raw values have been converted to Volts (×1e-6).

Electrode Layout#

Electrode layout — EEG · 128 sensors — 128 channels

Dataset Statistics#

Channel counts: 139 ch (n=21 recordings)

Sampling frequencies: 256.0 Hz (n=21 recordings)

NEMAR Processing Statistics#

The plots below are generated by NEMAR’s automated EEG pipeline. The histogram shows pipeline success for data cleaning and ICA decomposition, the percentage of data frames and EEG channels retained after artefact removal, line noise per channel (RMS, dB), and the age/gender distribution of participants.

class eegdash.dataset.DS007591(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

Delineating neural contributions to EEG-based speech decoding

Study:

Canonical:

Also importable as: DS007591, Sato2026_Delineating.

Modality: eeg; Experiment type: Motor; Subject type: Healthy. Subjects: 3; recordings: 21; tasks: 3.

Parameters:
  • cache_dir (str | Path) – Directory where data are cached locally.

  • query (dict | None) – Additional MongoDB-style filters to AND with the dataset selection. Must not contain the key dataset.

  • s3_bucket (str | None) – Base S3 bucket used to locate the data.

  • **kwargs (dict) – Additional keyword arguments forwarded to EEGDashDataset.

data_dir#

Local dataset cache directory (cache_dir / dataset_id).

Type:

Path

query#

Merged query with the dataset filter applied.

Type:

dict

records#

Metadata records used to build the dataset, if pre-fetched.

Type:

list[dict] | None

Notes

Each item is a recording; recording-level metadata are available via dataset.description. query supports MongoDB-style filters on fields in ALLOWED_QUERY_FIELDS and is combined with the dataset filter. Dataset-specific caveats are not provided in the summary metadata.

Examples

>>> from eegdash.dataset import DS007591
>>> dataset = DS007591(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.
