二十多年来,BESA Research 软件包为先进的 EEG 和 MEG 数据分析设定了标准。 BESA 研究将易于使用的界面与创新的、量身定制的分析方法和数据审查工具相结合,为进行 EEG/MEG 数据分析提供了一种方便且极其顺畅的途径。

BESA Data Analysis


BESA Research 7.1 允许快速轻松地测试假设、多源分析算法(包括皮层成像和体积成像方法)、与 MRI 和 fMRI 的集成以及适合年龄的模板头部模型 (FEM) 以及导入单个头部模型的选项(FEM) 通过 BESA MRI 2.1 生成。

更新后的软件提供了许多用于查看和处理 EEG 或 MEG 数据的新工具。使用为许多 EEG 和 MEG 文件格式实现的读取器直接读取原始数据,数据处理步骤包括数字滤波、人工制品检测和校正、相关性计算和频谱分析。

BESA Research 7.1涵盖信号处理和分析的全过程,从获取的原始数据到动态源图像,允许数据审查和处理;源蒙太奇和 3D 整体头部映射; ERP分析和平均;源定位和源成像;皮层映射和时频分析;源相干性和时频分析;增强大脑活动观察的源一致性。
