In 1987 the first commercially available TMS stimulator was developed and has evolved into today’s 200². These stimulators have been used in over 10,000 published research articles*. The 200² delivers single, monophasic pulses, has a simple user interface, and is easily integrated with external triggering and neuronavigation systems.
