Hypothesis
OpenMEEG aims to provide accurate solutions for electromagnetic forward problems in EEG, MEG, EIT, and intracranial EEG.
Conclusion
OpenMEEG is a state-of-the-art software that accurately computes lead fields for various electromagnetic problems.
Supporting Evidence
- OpenMEEG can compute lead fields for EEG, MEG, EIT, and intracranial EEG.
- It provides accurate solutions even with coarsely sampled meshes.
- OpenMEEG is open source and can be integrated with Python and Matlab.
Takeaway
OpenMEEG is a tool that helps scientists understand brain activity by accurately modeling how electrical signals travel through the head.
Methodology
OpenMEEG uses the Boundary Element Method to solve forward problems in quasistatic electromagnetism.
Limitations
OpenMEEG is limited to nested conductivity models and cannot handle inhomogeneous or anisotropic conductivity without using Finite Element Methods.
