# PURSUE N2pc Visual Search

**Dataset ID:** `ds007137`

_Couperus2025_N2PC_

**Canonical aliases:** `Couperus2021_N2pc`

> **At a glance:** EEG · Visual attention · healthy · 294 subjects · 294 recordings · CC0

## 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="ds007137", 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 Couperus2021_N2pc
ds = Couperus2021_N2pc(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/ds007137")
```

# PURSUE N2pc 视觉搜索

**数据集编号：** `ds007137`

_Couperus2025_N2PC_

**标准别名：** `Couperus2021_N2pc`

> **概览：** 脑电图（EEG） · 视觉注意力 · 健康人群 · 294名受试者 · 294条记录 · CC0许可

## 加载该数据集

本仓库仅为**索引指针**，原始脑电图（EEG）数据存储于其官方源地址（OpenNeuro / NEMAR）；[EEGDash](https://github.com/eegdash/EEGDash) 可按需流式加载该数据集，并返回 PyTorch / braindecode 格式的数据集对象。

python
# 安装eegdash库
from eegdash import EEGDashDataset

ds = EEGDashDataset(dataset="ds007137", cache_dir="./cache")
print(len(ds), "条记录")

你也可以通过标准别名加载该数据集——这些类已在`eegdash.dataset`中完成注册：

python
from eegdash.dataset import Couperus2021_N2pc
ds = Couperus2021_N2pc(cache_dir="./cache")

若该数据集已按照braindecode的Zarr格式镜像至Hugging Face Hub，你也可以直接拉取：

python
from braindecode.datasets import BaseConcatDataset
ds = BaseConcatDataset.pull_from_hub("EEGDash/ds007137")
