Electroencephalography (EEG) is a non-invasive technique which records electrical activity generated by the brain through sensors placed on the scalp.
EEG can help us to understand the processes involved in various cognitive tasks such as remembering, making decisions, paying attention and reading.
It can also be used to look at brain activity when a person is sleeping. Find out more about the work taking place in the sleep laboratory.
Three labs and data analysis tools
We house three dedicated EEG labs which can measure up to 128 channels. Two of these systems are from BioSemi and the third is from Brain Products. We utilise both active and passive electrode set-ups; the former has a quicker set-up time which can be useful when testing certain populations.
The labs are fully equipped with software to present high-fidelity visual and auditory stimuli to participants and a comprehensive range of tools are available for the analysis of the data. Complementary EEG systems are also available in the magnetic resonance imaging (MRI) and magnetoencephalography (MEG) suites to allow multi-modal imaging.
Dedicated prep areas
In addition to the labs, we also have a dedicated area for preparing participants for EEG, along with hair-washing facilities to remove electrode gel after an experimental session.
