Colgate EEG Lab Skip Navigation

ERP Laboratory

Electroencephalography (EEG) is one of the most documented neuroimaging (broadly defined) techniques available to neuroscientists studying human behavior. 
Professor Bruce Hansen and students prepare a test subject with an EEG neuroimaging net.

Additional Information

Electroencephalography itself involves placing surface electrodes on the scalp of a human participant and recording weak gross electrical signals generated by the brain.  Thus, in contrast to functional magnetic resonance imaging (fMRI), positron emission tomography (PET), or diffuse optical imaging (DOI) techniques, EEG is a more direct measure of neural activity whereas the former neuroimaging techniques yield measures of physiological changes that are only correlated with changes in neuronal activity.  Furthermore, EEG recordings can be time-locked to behavioral experimental paradigms (in the form of event-related potentials, or ERPs) thereby allowing for a wide variety of analyses focused on the temporal localization of different brain signals.  Thus, EEG (and related analyses) is a very powerful technique for assessing the temporal characteristics of the brain’s neuroelectric activity. 

Colgate's ERP lab is equipped with a state-of-the art EEG system that was funded through a National Science Foundation (NSF) Major Research Instrumentation (MRI) grant.  The system is intended for shared use by Colgate faculty and undergraduate research students exploring human behavior from multiple perspectives.  It is hoped that Colgate's ERP lab will provide a common tool connecting a diverse range of faculty and students interests and will facilitate both intradisciplinary and interdisciplinary work among researchers who may not otherwise collaborate. 

Faculty and student researchers who are interested in incorporating EEG or ERP measures into their research must complete the lab's training sessions (see contact information above to schedule your training sessions). If you have completed the training sessions, please visit the "Helpful Links" section above.  There, you will find a download link for the abridged reference manual for general lab protocols.
