27-participant EEG dataset — EEG: Visual Working Memory + Cabergoline Challenge.
Quickstart#
Install
pip install eegdash
Access the data
from eegdash.dataset import DS003519
dataset = DS003519(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)
Filter by subject
dataset = DS003519(cache_dir="./data", subject="01")
Advanced query
dataset = DS003519(
cache_dir="./data",
query={"subject": {"$in": ["01", "02"]}},
)
Iterate recordings
for rec in dataset:
print(rec.subject, rec.raw.info['sfreq'])

About This Dataset#
Visual Working Memory. Mostly unpublished! Beh data published here: 10.3758/s13415-018-0584-6. EEG data never published. Same sample as this published study: 10.1038/ncomms6394. 30 healthy participants (3 dropout) in a double-blind drug study. Total n=27. Drug was Cabergoline 1.25 mg. Subjects had IDs 305/405 - 330/430. The dual numbers were for session: 300s were first session, 400s were second session. Here we have simply put them in as session 1 and session 2. So Joe Smith would have been 305 on visit 1, then 405 on visit 2. If he got cab first we indicated that in the Sess1_Drug column. Task included in Matlab programming language. Data collected circa 2012-2013 in Laboratory for Neural Computation & Cognition at Brown. Check the .xls sheet under code folder for more meta data, incl. OSpan etc. - James F Cavanagh 02/15/2021

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.

Examples
>>> from eegdash.dataset import DS003519 >>> dataset = DS003519(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.
