Cognitive Electrophysiology

Cognitive electrophysiology is a direct measure of brain activity measured through electrodes placed on the scalp. It includes electroencephalography (EEG) and event-related potentials (ERP).

EEG/ERP studies examine changes in scalp-recorded brain electrical activity corresponding to cognitive processing in real time.


refers to the dynamic, ongoing electrical activity recorded during cognitive processing.


refers to relying on signal averaging to extract the activity reliably linked with specific sensory stimuli and/or motor responses (the electrical potentials that are related to specific events).

Cognitive electrophysiology is well suited for undergraduate research education

The equipment and supplies are relatively inexpensive, and yet the opportunities for learning are immense. It allows students to learn about neurobiology, physics, psychology, mathematics, engineering, statistics, and computer science and to integrate across these fields, which is important for real-world applications. The skills learned in an ERP lab are transferable to many areas of research and to practical applications of science in medicine, engineering, computer-human interaction, etc.
