The BIOMAG meeting is a biennial international conference with a focus on biomagnetism. The topic of biomagnetism includes the measurement of magnetic signals from the human body, such as brain activity, as well as the development of new magnetic sensors. The biomagnetism community is highly productive and generates thousands of high-profile publications a year on cognitive neuroscience, clinical neuroscience and cardiology, as well as the development of software tools and new sensor technology.
