The EEG Laboratory

The Antrobus EEG laboratory, located on the 7th floor of the NAC building, contains equipment to record and amplify electroencephalographic (EEG) signals (brain waves) from the human scalp. Participants are fitted with a comfortable latex recording cap that enables the researchers to collect brain waves from 160 recording sites simultaneously. Participants are seated comfortably in a sound-attenuating chamber and typically are asked to perform simple cognitive tasks, such as identifying sounds or discriminating colors. The laboratory contains sophisticated software that allows researchers to construct a map of brain activity. These maps are useful in pinpointing the temporal and spatial sources of mental functions such as language and attention.
