Intracranial EEG Epilepsy - Studies 3, 5 and 6 (Mayo Clinic; IEEG.org)

iEEG

Long-term clinical intracranial EEG recordings (subdural grid/strip and depth electrodes) from three patients with drug-resistant epilepsy, recorded at Mayo Clinic, Rochester, and originally shared via IEEG.org and Pennsieve Discover (Studies 3, 5 and 6). The recordings contain expert seizure annotations, with 41 runs totalling roughly 397 hours sampled at 500 Hz. Data were losslessly converted from MEF 2.0 to BrainVision format in BIDS, with participant demographics and clinical outcome information.

WIRED ICM Sample Dataset - Workshop on Intracranial Recordings in Humans, Epilepsy, DBS

ANAT iEEG Zarr

A sample intracranial EEG (iEEG) dataset prepared for the WIRED ICM course on intracranial recordings in humans, epilepsy, and deep brain stimulation (Paris, March 2024). It contains recordings from patients with epilepsy during naturalistic listening tasks (movie trailers and TIMIT sentences). It also includes illustrative examples of seizure-related activity and vagus nerve stimulator artifact.

SeizeIT2

EEG EMG

SeizeIT2 is a multicenter, prospective dataset of wearable behind-the-ear EEG, ECG, EMG and movement recordings from 125 adult and pediatric patients with focal epilepsy. Patients were monitored in five European epilepsy monitoring units with the Sensor Dot wearable device alongside standard video-EEG. The dataset contains about 11,640 hours of wearable data with 886 recorded focal seizures, annotated in BIDS-score compatible format, and supports the development and validation of seizure detection algorithms.

Dataset of intracranial EEG, scalp EEG and beamforming sources from epilepsy patients performing a verbal working memory task

EEG iEEG Zarr

This dataset contains simultaneously recorded scalp EEG and intracranial EEG (depth electrodes) from fifteen epilepsy patients undergoing intracranial monitoring while performing a modified Sternberg verbal working memory task. Encoding, maintenance, and recall are temporally separated. It includes electrode MNI coordinates with anatomical labels, trial-level behavioral information, and LCMV beamforming-reconstructed virtual sensor data for several cortical regions. The data support studies of working memory, connectivity, and replay of memory items.

A multimodal epilepsy dataset of paired 3-Tesla and 7-Tesla MRI and intracranial EEG (Penn 3T-7T, Pennsieve 662)

ANAT FUNC iEEG

A multimodal dataset of paired 3-Tesla and 7-Tesla MRI (structural and resting-state fMRI) from 30 patients with drug-resistant focal epilepsy. For 15 of these patients it also provides curated ictal and interictal intracranial EEG epochs (ECoG and SEEG) with electrode localizations in MNI space. Preprocessing derivatives (fMRIPrep, FreeSurfer, iEEG-recon) are included. This is a BIDS redistribution of Pennsieve Discover dataset 662.

Wakeful and sleep-like states in subdural ECoG (Pahwa et al., 2015): 4 patients, 64-channel grids

iEEG

Subdural electrocorticography (ECoG) recordings from four patients with intractable epilepsy, acquired with 8x8 electrode grids over left frontal, temporal and parietal cortex during clinical monitoring. For each patient, two wakeful and two sleep-like epochs were identified from video and audio of natural behaviour, with no task. The data support work on detecting wake and sleep-like states for future ECoG brain-computer interface applications.
