SEEG Recordings from Epilepsy Patients Performing a Visual Working Memory Task

Stereo-electroencephalography (SEEG) recordings acquired from patients with drug-resistant epilepsy while performing a visual working memory task. The dataset is 12.5 GB and organized according to the BIDS standard for iEEG data. It was authored by Ziwei Tian and last updated on May 7, 2026.

Use Cases

• Analyzing neural oscillations during working memory tasks based on SEEG recordings.
• Investigating brain network dynamics in epilepsy patients based on multi-contact electrode data.
• Developing models for memory encoding and retrieval based on high-frequency (2048 Hz) neural signals.
• Validating BIDS-standard iEEG data structures for data sharing and reuse.

Strengths

• Data is organized according to the BIDS standard, facilitating easy sharing and reusability.
• Recordings have a high sampling rate of 2048 Hz.
• The dataset size is 12.5 GB, indicating a substantial volume of neural signal data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Electrode placement was determined solely by clinical requirements, which may limit systematic coverage of brain regions.
