CCEP database of the Medical Informatics Platform

Single-pulse direct electrical stimulation of cortical regions in patients suffering from focal drug-resistant epilepsy who are explored using intracranial electrodes induces electrophysiological responses. Such cortico-cortical evoked potentials (CCEP) can be used to infer functional and anatomical brain connectivity. This pseudonymized database in BIDS-iEEG format contains stereotactic EEG data obtained in implanted epileptic patients who were candidates to resective surgery and undergone intracortical stimulations. The data were collected from a multicenter population of 217 patients. This database can contribute to the development and validation of human brain atlases and whole brain models by integrating relevant information from CCEPs.
