This study validates finite element models for directional DBS by comparing experimental measurements with different boundary condition configurations, finding Dirichlet conditions provide higher accuracy in predicting VTA volume.

The paper develops a BEM-based method to solve EEG/MEG forward problems for high-resolution head models in about 60 seconds.

This paper models microscopic electric field perturbations in a mouse brain sample to assess their impact on neuronal activation thresholds, finding modest effects compared to macroscopic predictions.

The paper compares dipole source reconstruction accuracy between 3-layer and 5-layer BEM-FMM models, finding that 3-layer models provide good localization but less accurate orientation, with AMR improving 5-layer accuracy.

This paper introduces an adaptive mesh refinement method to improve accuracy in electromagnetic simulations for brain stimulation and EEG, showing significant error reduction with minimal mesh expansion.

The paper introduces a MATLAB software package for TMS coil analysis and design, using FMM to compute fields and inductances with high accuracy.

The paper develops and validates a new EEG source localization algorithm using BEM-FMM, reciprocity principle, and TES forward model matrix, achieving high-resolution source reconstruction with low computational cost.
