About

TI-Toolbox is an open-source platform for temporal interference (TI) brain-stimulation research. It helps researchers explore how electrode placement and stimulation settings shape electric fields in the brain, bringing study planning, simulation, and analysis into one workflow.

Started as a side project in 2024, the toolbox supports both researchers new to TI modeling and experienced users working with larger studies. You can explore stimulation using standard head models or personalize a study with a participant’s MRI.

From a research question to results

  • Prepare your study — organize imaging data and build head models that represent the anatomy you want to study.
  • Explore stimulation — simulate electrode arrangements and visualize the resulting electric fields.
  • Find promising settings — search for electrode placements and currents that focus stimulation on your region of interest.
  • Compare and communicate — analyze target regions, compare results across participants, and create figures and reports.

Use the desktop interface to work through a study, or build on the same tools in scripts and notebooks when you need a custom workflow.

Built for research

TI-Toolbox brings related modeling tasks together so you can spend more time on your research questions. Organized projects, reusable settings, and saved results help you revisit analyses and share your work with collaborators.

The project is developed openly on GitHub, with contributions from the research community. Feedback, questions, and ideas help shape its development.
