This high temporal resolution lends itself well to the study of the earliest stages of information processing and the subsequent transitions from sensory-based perceptual processing to the higher cognitive operations that are necessary to successfully navigate through the complex stimulus-laden environment of everyday life.īasic Protocol 1 details the set-up for an EEG study participant. Many EEG researchers utilize an event-related potential (ERP) experimental design, in which a large number of time-locked experimental trials are averaged together, allowing the investigator to probe sensory, perceptual, and cognitive processing with millisecond precision. EEG measures the electrical activity of large, synchronously firing, populations of neurons in the brain with electrodes placed on the scalp.

Electroencephalography (EEG) is a non-invasive and relatively inexpensive method for assessing neurophysiological function that can be used to achieve this goal. Understanding the basic neural processes that underlie complex higher-order cognitive operations and functional domains is a fundamental goal of cognitive neuroscience.
