# Wang et al. 2024 — Brain Treebank: Large-scale intracranial recordings from naturalistic language stimuli

**Dataset ID:** `nm000253`

_Wang2024_et_al_Brain_

**Canonical aliases:** `BrainTreeBank`

> **At a glance:** IEEG · 10 subjects · 26 recordings · CC BY 4.0

## Load this dataset

This repo is a **pointer**. The raw EEG data lives at its canonical source
(OpenNeuro / NEMAR); [EEGDash](https://github.com/eegdash/EEGDash) streams it
on demand and returns a PyTorch / braindecode dataset.

```python
# pip install eegdash
from eegdash import EEGDashDataset

ds = EEGDashDataset(dataset="nm000253", cache_dir="./cache")
print(len(ds), "recordings")
```

You can also load it by canonical alias — these are registered classes in `eegdash.dataset`:

```python
from eegdash.dataset import BrainTreeBank
ds = BrainTreeBank(cache_dir="./cache")
```

If the dataset has been mirrored to the HF Hub in braindecode's Zarr layout,
you can also pull it directly:

```python
from braindecode.datasets import BaseConcatDataset
ds = BaseConcatDataset.pull_from_hub("EEGDash/nm000253")
```
