Quickstart#

Install

pip install eegdash

Access the data

from eegdash.dataset import DS007526

dataset = DS007526(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

PD-EEG: Resting-State & Walking EEG in Parkinson’s Disease

Overview

This dataset contains EEG recordings from Parkinson’s disease (PD) patients and healthy controls (HC), collected under two behavioral conditions: resting state (sitting) and walking. The dataset was acquired at the Neurology Institute, Tel Aviv Sourasky Medical Center.

Participants

  • Parkinson’s disease (PD): 116 participants

  • Healthy controls (HC): 28 participants

Inclusion criteria (PD):

  • Age 40–90

  • Hoehn & Yahr stage ≤ 3

  • MoCA ≥ 21

  • Able to walk independently

Exclusion criteria:

  • History of stroke or major neurological disorder

  • Brain surgery

  • Significant head injury

  • Inability to walk independently

All participants provided informed consent. The study was approved by the local ethics committee and conducted in accordance with the Declaration of Helsinki.

Experimental Design

Each participant underwent EEG recording under two conditions: 1. Resting State (144 Recordings)

  • Sitting

  • Eyes open

  • Duration: ~4 minutes

  1. Walking (133 Recordings) - Walking on a treadmill at a comfortable speed while holding the handrails. - Duration: ~4 minutes

Additional clinical data were collected, including: - Demographic data - LEDD (Levodopa Equivalent Daily Dose) - a measure of anti-parkinsonian medication dosage. - MoCA (Montreal Cognitive Assessment) - a global measure of cognitive function. - MDS-UPDRS - Movement Disorder Society Unified Parkinson’s Disease Rating Scale - the gold standard clinical rating scale for Parkinson’s Disease. - CTT - Color Trails Test - a measure of executive function and processing speed.

EEG Acquisition

  • System: 64-channel Geodesic EEG System 400 (EGI system)

- Montage: International 10–20 system

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: DS007526, Katzir2026.

Modality: eeg; Experiment type: Clinical/Intervention; Subject type: Parkinson's. Subjects: 144; recordings: 277; tasks: 2.

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 DS007526
>>> dataset = DS007526(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.
