Invasive electrophysiological patient recordings from the human brain during memory tasks with pupilometry (MC_005)


Data comprise intracranial EEG (iEEG) brain activity, including electrocorticography (ECoG) signals, recorded from over 100 electrodes implanted in one patient throughout various brain regions. These iEEG signals were recorded in epilepsy patients undergoing invasive monitoring and localization of seizures when they were performing a battery of four memory and cognitive tasks lasting approx. 1 hour. Gaze tracking on the task computer screen as well as pupilometry was also recorded together with behavioral performance. The recordings were collected from a minimum of one daily session (run) during a two-week long hospital stay for the seizure monitoring with at least one task from the battery completed. Each dataset comes from one patient and includes metadata about anatomical coordinates of every electrode contact, labels for each electrode contact channel, and timing of events in each task.  All data are stored in BIDS (Brain Imaging Data Structure) format for efficient signal processing supported by the International Neuroinformatics Coordinating Facility), and were collected at Mayo Clinic (USA) or at the Wroclaw Medical University (Poland). These unique datasets arerelevant for anyone interested in neurology, neuroscience and neurophysiology of human memory and cognition.
