Quickstart#

Install

pip install eegdash

Access the data

from eegdash.dataset import DS003420

dataset = DS003420(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

Filter by subject

dataset = DS003420(cache_dir="./data", subject="01")

Advanced query

dataset = DS003420(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

Iterate recordings

for rec in dataset:
    print(rec.subject, rec.raw.info['sfreq'])

About This Dataset#

Dataset 1

Presentation

This dataset was collected between 2012 and 2013 in Rennes (France) during two conditions (visual naming and spelling tasks). The dataset consists of naming and spelling the names of visually presented objects. The data was collected in the Rennes University Hospital. This experiment was approved by an independent ethics committee and authorized by the French institutional review board (IRB): “Comite de Protection des Personnes dans la Recherche Biomedicale Ouest V” (CCPPRB-Ouest V). This study was registered under the name “conneXion” and the agreement number: 2012- A01227-36.

This experiment was approved by an independent ethics committee and authorized by the French institutional review board (IRB): “Comite de Protection des Personnes dans la Recherche Biomedicale Ouest V” (CCPPRB-Ouest V). This study was registered under the name “conneXion” and the agreement number: 2012- A01227-36.

Participants

Twenty-three right-handed healthy volunteers of whom 12 females, with an age range between 19 and 40 years (mean age 28 year),and 11 males with an age range between 19 and 33 years (mean age 23 years) participated in this study. (See participants.json and participants.tsv for more details)

Experiment

  • The experiment begins with the verification of inclusion/exclusion criteria.

  • The participants read the information notice and the consent form.

  • Then they sign two questionnaires.

  • One subject –>Two conditions (naming and spelling)–> two runs for each condition.

  • Each run contains 74 stimuli.

  • The spelling task always follow the naming task and its instruction was not given before the naming task was completed to avoid any reminiscence of words orthographic structures

  • Each run contains balanced numbers of animals and objects as well as long and short words.

  • Pictures are presented on a screen using a computer and the experimental paradigm is presented using E-prime Psychology Software Tools.

  • The responses produced by the participants were collected via a Logitech microphone and analyzed to detect onsets of speech using Praat v5.3.13(University of Amsterdam, 1012VT Amsterdam, The Netherlands).

EEG acquisition

  • HD-EEG system (EGI, Electrical Geodesic Inc., 256 electrodes)

  • Sampling frequency: 1000Hz

  • Impedances were kept below 5k

API Reference#

Use the DS003420 class to access this dataset programmatically.

class eegdash.dataset.DS003420(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

OpenNeuro dataset ds003420. Modality: eeg; Experiment type: Other; Subject type: Healthy. Subjects: 23; recordings: 92; tasks: 0.

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.
