About

Roman Rethwilm is a rising figure in non-invasive brain stimulation research, with a focused expertise in optimizing Transcranial Magnetic Stimulation (TMS) methodology. His work centers on two critical pillars: improving the reliability of TMS targeting and understanding how fundamental stimulation parameters affect measurement outcomes. Rethwilm’s major contribution is the development of the Semi-Automated Motor Hotspot Search (SAMHS) framework, a landmark methodological advance that standardizes the crucial first step of motor hotspot identification. This work, which has already garnered 10 citations since 2023, addresses a long-standing challenge in the field by reducing operator dependency and enhancing reproducibility in TMS protocols. In his most recent 2025 study, Rethwilm further demonstrates his impact by systematically investigating how pulse shape and current direction influence test-retest reliability and variability of single-pulse TMS outcomes. This research is vital for establishing more robust experimental designs and clinical applications. By tackling these foundational methodological issues, Rethwilm is providing the tools and evidence needed to increase the rigor and reproducibility of TMS research, making him a key contributor to advancing the field’s technical standards.
