背景:颅内脑电图数据为研究人脑功能提供了独特的时空精度。由于新的iEEG数据共享实践以及与临床医生的更紧密合作,大型数据集最近变得可访问。然而,这些数据集的复杂性带来了新的挑战,特别是关于iEEG的可视化和解剖显示。
方法:我们介绍HiBoP,专为大型患者组和多个实验设计的多模态可视化软件。其主要功能包括动态显示任务/刺激引起的iEEG反应,感兴趣的区域和电极的定义,以及组级和个体级3D解剖功能数据之间的转换。
结果:我们提供了一个用例,其中包含来自36名患者的数据,以揭示触觉刺激后的整体皮质动力学。我们使用HiBoP可视化高伽马响应[50-150Hz],并定义了初级体感和运动前皮质以及顶叶小脑的三个主要反应成分。与现有方法的比较若干iEEG软件现在公开可用,具有突出的分析特征。然而,大多数是用语言(Python/Matlab)开发的,这些语言是为了方便用户包含新的分析,而不是可视化的质量。HiBoP代表了一个可视化工具开发的视频游戏标准(统一/C#),并快速进行详细的解剖分析,跨越多个条件,病人,以及易于向第三方软件出口的模式。
结论:HiBoP提供了一个用户友好的环境,极大地促进了对大型iEEG数据集的探索,并帮助用户破译微妙的结构/功能关系。
BACKGROUND: Intracranial EEG data offer a unique spatio-temporal precision to investigate human brain functions. Large datasets have become recently accessible thanks to new iEEG data-sharing practices and tighter collaboration with clinicians. Yet, the complexity of such datasets poses new challenges, especially regarding the visualization and anatomical display of iEEG.
METHODS: We introduce HiBoP, a multi-modal visualization software specifically designed for large groups of patients and multiple experiments. Its main features include the dynamic display of iEEG responses induced by tasks/stimulations, the definition of Regions and electrodes Of Interest, and the shift between group-level and individual-level 3D anatomo-functional data.
RESULTS: We provide a use-case with data from 36 patients to reveal the global cortical dynamics following tactile stimulation. We used HiBoP to visualize high-gamma responses [50-150 Hz], and define three major response components in primary somatosensory and premotor cortices and parietal operculum.
UNASSIGNED: Several iEEG softwares are now publicly available with outstanding analysis features. Yet, most were developed in languages (Python/Matlab) chosen to facilitate the inclusion of new analysis by users, rather than the quality of the visualization. HiBoP represents a visualization tool developed with videogame standards (
Unity/C#), and performs detailed anatomical analysis rapidly, across multiple conditions, patients, and modalities with an easy export toward third-party softwares.
CONCLUSIONS: HiBoP provides a user-friendly environment that greatly facilitates the exploration of large iEEG datasets, and helps users decipher subtle structure/function relationships.
