Researchers from the University of Illinois Urbana-Champaign, working with domestic and international collaborators, have combined three imaging techniques to detect the timing and location of brain responses to a stimulus. The researchers said the study is the first to combine the three technologies for simultaneous imaging of brain activity.
The trimodal approach combines EROS (event-related optical signal), a technique that tracks the activity of neurons near the surface of the brain using near-infrared light; functional MRI (fMRI); and electroencephalography (EEG).
A new approach to brain imaging combines functional MRI, electroencephalography, and a technique known as EROS, which shines near-infrared light on the scalp to…
