Scalp EEG recordings during CANTAB battery of tasks probing memory and executive functions in epilepsy patients

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.本数据集包含86名癫痫患者在完成五项经临床验证的CANTAB成套测验（CANTAB battery）任务期间的连续癫痫脑电图（EEG）监测片段。该脑电图记录采集自美国明尼苏达州罗切斯特市梅奥诊所（Mayo Clinic），采用31通道Quantum系统（Natus公司，美国威斯康星州米德尔顿），电极布局遵循10-20系统，参考电极为'Cpz'；采样率为256Hz，硬件高通滤波器截止频率为0.1Hz。研究同步提供了来自CANTAB数据库的特定认知功能标准化行为指标，该指标以健康对照人群的年龄和性别为常模计算得到Z分数（z-score）。时间戳标记了各项CANTAB测验按成套测验推进顺序，从首个任务到末个任务的各阶段起始节点。元数据中还记录了测验过程中各类事件的额外临床信息，包括癫痫发作或任务间休息情况。
