Event Related Potentials (ERP)

Event Related Potentials (ERP)

ERP Facility

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.

At the ERP Faciltiy, 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.
