In the study of human brain function, simultaneaous multimodal measurements are becoming more and more common. In this context, fNIRS and EEG are getting a lot of interest. The two technologies provide complementary information and therefore together they offer a more comprehensive picture. In addition, both are non-invasive, as well as relatively affordable, and recent advancements have made it possible to develop devices that are fully wearable. The latter allows for a larger variety of experimental set-ups, including more naturalistic studies. For the same reason, this combination is very suitable for a wide range of populations.
During this workshop, we will bring attention to the potential of combined fNIRS-EEG research and will discuss key technological and methodological aspects that should be taken into consideration when designing experiments that integrate the two. We will present solutions for accurate synchronization of the two data streams, as well as placement of the sensors on the scalp. In a second part, we will also have an interactive demonstration and introduce 'Combined EEG-fNIRS optode holder', which allows positioning optodes and electrodes on the same location, while avoiding interference.
