Multicenter iEEG Sleep Atlas

The Multicenter iEEG Sleep Atlas is an international collaboration collecting intracranial electroencephalography (EEG) recordings from patients with drug-resistant focal epilepsy implanted with stereo-EEG electrodes in addition to baseline clinical information, anatomical scans, and post-surgical assessment.

Included in the project are 24-hour and resting state recordings with sleep/wake annotations for sleep stage as well as all source codes used within this project. iEEG data is stored in BIDS standard format, optimized for re-use and data sharing, and can be visualized online in this project’s Electrophysiology Browser.

This project is a collaboration across 11 sites in 6 countries, targeting the understanding of region-specific differences in human sleep and generate knowledge on the distinct participation of various cortical regions in sleep. It aims to generate a unique dataset of 200 patients that will allow to study direct cortical recordings in the human brain as only possible in the context of pre-surgical epilepsy evaluation. Data collection is coordinated and harmonized across sites through this collaboration.
