ERP-FRP Laboratory
When brain cells fire, they release tiny amounts of electricity that travel through the brain and scalp to escape into the outside world. This bid for freedom is very convenient because it allows us to measure a person's brain responses from outside their head. We do this using small sensors that are sewn into a soft cap.
In the MACCS ERP-FRP lab, we measure two types of brain responses: event-related potentials (ERPs) and fixation-related potentials (FRPs). An ERP is the average brain response to a particular stimulus, such as a high-pitched musical note or the photo of a face. An FRP is the average brain response to one part of a whole visual stimulus, such as the eyes in a face, or a word written in a sentence. Thanks to our FRP collaborators in Salzburg, MACCS now runs one of only five research-active FRP systems in the world.
