Human Intracranial Database (release-5)

The Human Intracranial Database (HID) is a collection of stereotactic electroencephalography (sEEG) data in epileptic patients, performing up to eight behavioral tasks. The behavioral tasks were used as functional localizers: short and classic task paradigms designed to activate large-scale neural networks involved in language processing (LEC1 and LEC2), verbal and visuo-spatial working memory (MVEB and MVIS), visual attention (VISU), motor behavior (MOTO), high-level visual (MCSE) and auditory perception (AUDI). Furthermore, most patients were also recorded during resting state (REST) and a series of tests designed to evaluate whether specific types of actions can generate artifacts (ARFA). The sEEG data were obtained via several sEEG depth-electrodes (linear arrays with up to 20 contacts) that were implanted in each patient in a stereotactic surgery. Coordinates of the sEEG electrode contacts are provided in the individual brain space of each patient as well as in a reference brain space (MNI ICBM 152). Semantically sEEG electrode contacts were linked to brain areas of the MarsAtlas, but can be positioned on the individual anatomy for checking purposes.

人类颅内数据库（Human Intracranial Database，HID）是一个收录癫痫患者立体定向脑电图（stereotactic electroencephalography，sEEG）数据的数据集，所有受试者需完成至多8项行为任务。这些行为任务均作为功能定位范式：包括用于激活语言处理相关大规模神经网络的经典短任务（LEC1与LEC2）、语言与视觉空间工作记忆任务（MVEB与MVIS）、视觉注意任务（VISU）、运动行为任务（MOTO）、高级视觉任务（MCSE）以及听觉感知任务（AUDI）。此外，多数患者还会在静息状态（REST）以及一系列用于评估特定动作是否会产生伪影的测试（ARFA）期间被同步采集数据。该立体定向脑电图数据通过多根立体定向脑深部电极采集，此类电极为最多含20个触点的线性阵列，经由立体定向手术植入每位患者颅内。立体定向脑电图电极触点的坐标以两种形式提供：每位患者的个体脑空间坐标，以及参考脑空间坐标（MNI ICBM 152）。语义层面上，立体定向脑电图电极触点已与MarsAtlas脑区图谱建立关联，同时也支持基于个体解剖结构进行触点定位以作核查使用。
