Event-Related Potential (ERP)

An event-related potential (ERP) is the measured brain response that is the direct result of a specific sensory, cognitive, or motor event.

Event-related potentials (ERP)

Measures the firing of groups of neurons in the cortex. As a person views or listens to specific types of information, neuronal activity creates small electrical currents that can be recorded from non-invasive sensors placed on the scalp. ERP provides excellent information about the timing of processing, clarifying brain activity at the millisecond pace at which it unfolds.
