SWEC iEEG Dataset: 9,328 Hours of Brain Recordings from 68 Epilepsy Patients

68 subjects with pharmacoresistant epilepsy contributed fully anonymized multi-channel intracranial electroencephalography (iEEG) recordings. The dataset contains 9,328 hours of signal and 704 annotated ictal events, collected at the Sleep Wake Epilepsy Center (SWEC) of the Inselspital in Bern, Switzerland. It was published by NeuroTec on the Hugging Face platform, with a last update in August 2025.

Use Cases

• Train seizure detection models based on the 704 annotated ictal events.
• Analyze pre-surgical iEEG patterns based on multi-channel recordings from pharmacoresistant epilepsy patients.
• Develop time-series forecasting models for neurological events using 9,328 hours of continuous brain signal data.

Strengths

• Contains a substantial volume of 9,328 hours of iEEG signal.
• Includes clinically relevant annotations for 704 seizure (ictal) events.
• Data is sourced from a specialized clinical center (SWEC, Inselspital Bern) and is fully anonymized.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count, file formats, and license information are unknown, which may limit suitability assessment.
