If you joined Rory and I in any of our 'Introduction to TMS Physiology' Webinars you'll have seen the slide about the importance of current direction when stimulating the motor cortex. Many researchers don't consider how this differs between TMS devices; so in the article below we try to clarify this matter for those who may be new to the field, or are considering the purchase of new/different equipment.
