并且,我们还可以使用源定位(source localization)方法,例如最小范数估计(MNE)和波束形成(beamformer)。这些源定位方法可以将传感器的信号映射到大脑每个体素上,并且保留了时间精度,以便在ROI中构建多元时间序列,从而进行解码分析。我们还可以使用被试的解剖像(T1)和功能像(fMRI)来更精确地定义ROI,以提高源定位的质量。
Pythoninverse problemsopen-source softwareSource localization from M/EEG data is a fundamental step in many analysis pipelines, including those aiming at clinical applications such as the pre-surgical evaluation in epilepsy. Among the many available source localization algorithms, ...

EEG source localization We used L2 minimum norm estimation, as implemented by MNE-Python, to obtain cortical current estimates from our sensor level data. The FreeSurfer average brain template from FreeSurfer 674was used to construct the boundary element head model and forward operator for the source...

Next, we install all necessary packages and install Matlab Engine API for Python We also provide a make tool for simple administration of notebooks’ code. For example, the user may execute makeeverything in terminal in order to generate all source code files. See README.md file in the re...
We developed a Matlab-based EEG processing pipeline that complements previous approaches in other programming languages, such as the MNE-BIDS-pipeline (https://mne.tools/mne-bids-pipeline/1.3/index.html) in Python. Matlab is widely used by the EEG community and enabled us to use well-establishe...
Source localization MNE toolbox22 combined with gumpy35 Python toolbox were used for EEG processing and for source localization. First, cortical surface reconstruction using FreeSurfer46. Second, the forward solution and the forward model were computed using the boundary-element model (BEM)47. Thereaf...
