MR-Compatible Integrated Eye Tracking System

Abstract

This instrumentation grant was used to purchase state-of-the-art, high-resolution video eye tracker that can be used to monitor the subjects' eye movements as they perform visual search tasks, such as searching a visual image for a camouflaged target. The eye tracker has been fully functional for approximately a year and a half now, and has been functioning properly during this entire period. We have been using this valuable piece of equipment in our experiments both inside the magnetic resonance (MR) scanner as well as outside the scanner. Measuring subjects' eye movements in this fashion allows us to not only study the role of changes in eye position and shifts of visual attention on visual perception, but will also helps us factor out potentially confounding effects of eye movements to the observed brain activity.
