Eyelink 1000 Plus

The UConn Brain Imaging Research Center (BIRC) houses an Eyelink 1000 Plus eye tracker, which is the fastest, most accurate, and most precise eye tracker for MRI environments. 

Eye-tracking during scans allows researchers to monitor participants' eye movements while simultaneously collecting fMRI data, and subsequently employ advanced analytical techniques such as fixation-related (FIRE) fMRI.  

The eye tracker can be used with multiple stimulus presentation software including Experiment Builder, PsychoPy, E-Prime, NBS Presentation, Psychtoolbox, and OpenSesame.

If you are interested in adding eye tracking as an additional measure to fMRI, please contact gitte.joergensen@uconn.edu.

Dr. Joergensen has many years of eye-tracking experience and will provide support with how to best integrate eye tracking with fMRI, as well as other aspects of eye-tracking.
