In the EEG Lab, which was opened in 2013, researchers can test language processing in the most direct way: by measuring exactly when the brain responds to specific stimuli. The EEG Lab is comprised of three set-ups with BioSemi Active Two system (64 + 8 channels) with Actiview, and two workstations for data analysis with Brain Vision Analyzer software.

Electrical activity in the brain

Electroencephalography (EEG) is a way to record the electrical activity of the brain. In the EEG Lab, researchers study how the brain responds to spoken, signed, or written language. EEG can tell us a great deal about the time-course of language processing. While the brain is constantly producing low-frequency electrical activity, researchers are interested in the electrical activity produced as a response to some specific stimuli. This phenomenon can be used to study many types of linguistic research questions.  

These changes in frequency and polarity of electrical brain activity are called event-related potentials (ERP). There are several well-known and predictable event-related potentials called ERP “components” that researchers look for in the presence of specific linguistic manipulations. In this way, researchers are able to measure, for example, the brain’s electrical activity in response to an unexpected word, an ungrammatical sentence, an infrequent word, or changes in prosody.

The EEG Lab is situated in the Lipsius Building room 1.04.
