A new automated method, AutoHS, streamlines Transcranial Magnetic Stimulation (TMS) by precisely locating the motor hotspot. This innovation enhances reproducibility and speed in brain stimulation research and clinical applications.

Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Computational Biology

Background:

  • Transcranial Magnetic Stimulation (TMS) is a key technique for brain research and therapy.
  • Technological advancements like neuronavigation and robotics have improved TMS reliability.
  • Current TMS protocols lack automated setup procedures, particularly for determining stimulation intensity, leading to time-consuming manual processes and variability.

Purpose of the Study:

  • To develop an automated procedure for identifying the motor hotspot (HS) position in Transcranial Magnetic Stimulation (TMS).
  • To compare the efficacy, reproducibility, and speed of the automated procedure against manual methods.
  • To establish the first fully automated setup for TMS protocols by integrating the developed model with existing robotic and automated threshold estimation techniques.

Main Methods:

  • Development of a probabilistic Bayesian model named AutoHS for automatic HS identification.
  • Comparison of AutoHS with manual HS identification procedures using virtual and real experimental data.
  • Integration of AutoHS with robotized TMS and automated motor threshold estimation for a complete automated workflow.

Main Results:

  • The AutoHS model demonstrated superior reproducibility and speed compared to classical manual procedures for HS identification.
  • The automated procedure was found to be at least as reliable as manual methods.
  • The combined approach represents the first fully automated setup procedure for TMS protocols.

Conclusions:

  • The AutoHS system offers a more efficient, reproducible, and reliable method for TMS setup.
  • This automation reduces inter-experimenter variability, simplifying TMS protocol execution in research and clinical settings.
  • The fully automated TMS setup procedure facilitates wider adoption and standardization of TMS applications.
