Eye Tracking Facility
Our eye tracking lab uses an ASL EYE-TRAC 6000 series remote optic system (60Hz) with an Apple Mac Pro stimulus display and control computer running both Windows and OS X. It is a complete eye tracking system for situations where the stimulus presented to the subject is restricted to a single surface such as a computer monitor. The system's measurement is displayed in real-time as a cursor superimposed on the viewed image from another video source showing the subject's field of view. A second camera displays a wide angle view of the subject and may be used to quickly locate the eye. Recorded data include time, x and y eye position coordinates and pupil diameter. External data events/marks can be recorded along with eye tracker data via Ethernet communication. Eye position coordinates correlate to specific areas on the surface being viewed. Included with the system is ASL's EYENAL and FIXPLOT data analysis software. A secondary eye tracking system is available in the TMS laboratory. This is a faster SMI RED (120Hz) system ( http://goo.gl/v2tyv ) , and includes a license for SMI’s eye data analysis and stimulus display software (BeGaze and Experiment Center). This system is also connected with an Apple Mac Pro stimulus display and control computer.Neuroimaging Facility: We have two research-dedicated scanners in our shared facility. The first is a 3 Tesla head-dedicated Siemens Allegra MRI scanner, with phased-array, head, and surface coils, capable of anatomic and functional MRI as well as proton NMR spectroscopy (MRS) and the second is a 3 Tesla Siemens Skyra MRI scanner, a whole body wide-bore clinical standard MRI scanner, equipped with current state-of-the-art transmit/receive system and a variety of RF coils, capable of anatomic and functional MRI and MRS.
