Quickstart#

Install

pip install eegdash

Access the data

from eegdash.dataset import DS007609

dataset = DS007609(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

Filter by subject

dataset = DS007609(cache_dir="./data", subject="01")

Advanced query

dataset = DS007609(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

Iterate recordings

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

Resting-State EEG and Trait Anxiety

This dataset contains resting-state EEG recordings from 51 participants, collected as part of a study examining the relationship between resting-state EEG alpha/theta power, oscillatory dynamics, and trait anxiety.

Participants

51 right-handed undergraduate students (25 female) from the University of Alberta, aged 17-51 years (mean = 20.4, SD = 4.9), participated for course credit.

Recording

EEG was recorded using a 256-channel EGI HydroCel Geodesic Sensor Net with Net Amps amplifier. The original sampling rate was 500 Hz. Online reference was Cz.

Paradigm

Participants completed a resting-state protocol consisting of alternating 1-minute eyes-open (EO) and 1-minute eyes-closed (EC) blocks, repeated twice (EO-EC-EO-EC), for a total of 4 minutes. Transitions between blocks were signaled by an auditory beep.

Preprocessing

Data were preprocessed in EEGLAB (MATLAB) with the following steps: - Bandpass filter: 0.1-50 Hz - Line noise removal: CleanLine at 60 Hz and 120 Hz - Channel rejection: kurtosis-based (2x threshold), applied twice - Re-referencing to the average - ICA decomposition (runica, extended) - Artifact component removal via ICLabel (>0.8 probability threshold) + visual inspection - Spherical interpolation of removed channels

Phenotype Data

The phenotype/ directory contains anxiety and personality questionnaire scores: - STAI: State-Trait Anxiety Inventory (Spielberger et al., 1983) - TIPI: Ten-Item Personality Inventory, emotional stability subscale (Gosling et al., 2003) - BIS/FFFS: Behavioural Inhibition Scale and Fight-Flight-Freeze System

from the RST-PQ (Corr & Cooper, 2016), with Heym and Jackson factor structures. BIS data are unavailable for the first 5 participants.

Ethics

This study received ethics approval from the University of Alberta Research Ethics Board. Project Name: “Physiological Bases of Human Memory”, No. Pro00113334.

Modality: eeg; Experiment type: Affect; Subject type: Healthy. Subjects: 51; recordings: 51; 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.
