| # Categorized Free Recall: Delayed Free Recall of Word Lists Organized by Semantic Categories | |
| **Dataset ID:** `ds004809` | |
| _Herrema2023_Categorized_Free_Recall_ | |
| **Canonical aliases:** `catFR_Categorized_Free_Recall` · `CatFR` | |
| > **At a glance:** IEEG · Visual memory · epilepsy · 252 subjects · 889 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="ds004809", 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 catFR_Categorized_Free_Recall | |
| ds = catFR_Categorized_Free_Recall(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/ds004809") | |
| ``` | |
