About This Dataset#

This is the preprocessed dataset used for study “Characterization of spatiotemporal dynamics in EEG data during picture naming with optical flow patterns”.

The Picture Naming Task study included sixteen native French-speaking men, ranging in age from 18 to 70 years old. The participants met the inclusion criteria, which required normal or corrected-to-normal vision and hearing, as well as right-handedness, as determined by a handedness questionnaire [Oldfield1971assessment]. Exclusion criteria were in place to ensure that participants had no history of neurological or psychiatric disorders, drug addiction, or head trauma. In total 20 subjects were included in the study. The four first subjects’ data was excluded due to hardware failure.

Participants were required to name the pictures shown on a screen. Each event (random pictures) has three phases: [-2s, 0s] is the baseline (pre-visual-stimulation); at time 0 picture is shown on screen; then [0s, 1.5s] post-stimulation phase; [1.5s, 3s], naming phase. Pictures used in the task were selected from the Snodgrass & Vanderwart black-and-white line drawing corpus [Snodgrass1980standardized]. “./code/experiment_schema.pdf” showed the task design.

Data pre-processing pipeline is illustrated in “./code/preprocess_pipeline.pdf”. In total, 270 trials each for the 16 subjects.

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.

Canonical:

Also importable as: DS004554, Volpert2023.

Modality: eeg. Subjects: 16; recordings: 16; tasks: 1.

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 DS004554
>>> dataset = DS004554(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.
