Scalp EEG recordings during CANTAB battery of tasks probing memory and executive functions in epilepsy patients
Description
The dataset comprises continuous sections of EEG epilepsy monitoring from 86 epilepsy patients, during CANTAB battery performance of five clinically validated tasks. These EEG recordings were obtained at the Mayo Clinic (Rochester, MN, USA) using a 31-channel Quantum system (Natus, Middleton WI, USA) based on 10-20 electrode placement system with 'Cpz' as the reference (256 Hz sampling rate with hardware-based high-pass filter with a 0.1 Hz cut-off frequency). Standardized behavioral measures of particular cognitive functions are provided from the CANTAB database as z-scores to the age and gender of a healthy control population. Timestamps mark the beginning of subsequent phases of particular CANTAB tasks from the first to the last one in the same battery order of progression. Additional clinical information about any events during the batter performance, including seizures or breaks between tasks, is described in the metadata.
