56-participant EEG dataset — EEG: Simon Conflict in Parkinson's.
Quickstart#
Install
pip install eegdash
Access the data
from eegdash.dataset import DS003509
dataset = DS003509(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)
Filter by subject
dataset = DS003509(cache_dir="./data", subject="01")
Advanced query
dataset = DS003509(
cache_dir="./data",
query={"subject": {"$in": ["01", "02"]}},
)
Iterate recordings
for rec in dataset:
print(rec.subject, rec.raw.info['sfreq'])

About This Dataset#
Simon conflict task with cost of conflict reinforcement manipulation. 28 Parkinson patients and 28 matched controls. Task adapted from here: 10.1038/ncomms6394. Beh data first published here: 10.1016/j.cortex.2017.02.021. EEG published here: 10.1016/j.neuropsychologia.2018.05.020. PD came in twice separated by a week, either ON or OFF medication. CTL only came in once. Task included in Matlab programming language. Data collected circa 2015 in Cognitive Rhythms and Computation Lab at University of New Mexico. Subjs also had an acceleromter taped to their most tremor affected hand. X, Y, Z dimensions recorded throughout. Check the .xls sheet under code folder for more meta data. Triggers are complicated. See CC_Triggers.mat under code folder. Many analysis scripts are included; no idea how these hold up. Many are old. - James F Cavanagh 02/08/2021

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 DS003509 >>> dataset = DS003509(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.
