Note: Images show multiple slices sweeping through each orientation with TI field intensity overlaid in color on grayscale T1 anatomy. Overlay opacity is reduced to show underlying anatomy. Each series shows 7 slices from posterior to anterior (axial), left to right (sagittal), and posterior to anterior (coronal).

Methods

We kindly ask to report results from simulations performed with this tool using the following boilerplate.

Boilerplate Text

Electromagnetic field simulations were performed using the TI-CSC 2.0 (Transcranial Stimulation Computational Suite), which integrates SimNIBS for finite element modeling of transcranial electrical stimulation. Head models used isotropic conductivity values for different tissue types. Temporal interference (TI) stimulation was simulated using two pairs of electrodes in unipolar configuration. Electrode positions were defined using the EGI_template.csv electrode positioning system. The finite element method was used to solve Laplace's equation for the electric potential distribution in the head model. Electric field distributions and temporal interference patterns were calculated and analyzed using custom analysis pipelines. All simulations were performed using SimNIBS (www.simnibs.org) with head models derived from individual anatomical MRI data processed through the TI-CSC preprocessing pipeline.
