SimNIBS¶
SimNIBS is a free and open source software package for the Simulation of Non-invasive Brain Stimulation. It allows for realistic calculations of the electric field induced by transcranial magnetic stimulation (TMS) and transcranial electric stimulation (TES).
- A SimNIBS workflow consists of three main parts:
Generate high-quality head models from MR images
Set up and run simulation in the graphical user interface, MATLAB or Python
Visualize simulation results, and transform them to FsAverage or MNI space.

Warning
SimNIBS is a research tool. Clinical usage is not supported or advised. In particular, SimNIBS was not tested to give accurate results in the presence of pathological condition
News¶
Version 3.2.2 is now avaliable. This version includes a number of bug fixes and small improvements. Please see details in changelog.
Version 3.2 is now avaliable featuring TMS optimization using the ADM method (contributed by Luis Gomez), TES field strength and brain network optimization and magnetic field calculations for MRCDI and MREIT
Version 3.1 is now avaliable. This version features TDCS electrode optimization, TMS coil position optimization (contributed by Konstantin Weise and Ole Numssen) and even faster FEM solvers for leadfield calculations
Version 3.0 is now available. It is a major update of SimNIBS. Expect much faster simulations and easier visualizations!
