EEGDash — the Python library for 700+ BIDS-first EEG/MEG/EMG/fNRIS/iEEG datasets.

The open catalog of EEG / MEG datasets — indexed, described, and loadable with one line of Python.

Welcome to the official Hugging Face org for EEGDash. Raw EEG/MEG recordings are never rehosted here — each dataset on this page is a pointer to its canonical source (OpenNeuro, NEMAR, or the lab that collected it), and EEGDashDataset handles download, caching, and conversion to a PyTorch-ready braindecode object. One CSV drives the whole catalog; every card you see here regenerates from it automatically.

Catalog shape

In numbers: the archive indexes 736 EEG / MEG datasets totalling 40,361 subjects, 222,750 recordings, and 85,298 hours of signal. 600+ are already mirrored on 🤗 and growing daily, sourced from OpenNeuro (546) and NEMAR (190). By recording type: 571 EEG · 73 iEEG · 55 MEG · 22 fNIRS, plus a handful of multimodal combos.

Featured datasets

A handful of representative entries, grouped by population. Every slug links to its HF card; every card links back to the canonical source.

Get started in 30 seconds

pip install eegdash

from eegdash import EEGDashDataset

# Load any dataset in the catalog by its ID…
ds = EEGDashDataset(dataset="ds002718", cache_dir="./cache")

# …or by canonical alias — every known name is a registered class:
from eegdash.dataset import Wakeman2015
ds = Wakeman2015(cache_dir="./cache")

# …or pull a Hub-mirrored, pre-windowed Zarr copy:
from braindecode.datasets import BaseConcatDataset
ds = BaseConcatDataset.pull_from_hub("EEGDash/ds002718")

# EEGDash datasets ARE braindecode datasets — plug into PyTorch unchanged.
from torch.utils.data import DataLoader
loader = DataLoader(ds, batch_size=32, shuffle=True)
