Want to do #eyetracking in #fMRI without eye tracker? Check out our #preprint!
@CYHSM & I developed #DeepMReye, a #DeepLearning framework to decode gaze position from the MR-signal of the eyeballs. No camera needed! w/@doellerlab

How does MR-based #eyetracking work?
The orientation of the eyeballs naturally reflects gaze direction. This & the strong MR-signal variations induced by eye movements serve as the basis for gaze decoding.

What is #DeepMReye & what does it do?
It's a #CNN that uses the multi-voxel-pattern of the eyeballs to decode gaze position on the screen. It can perform #eyetracking even in existing #fMRI data.
We tested it on 268 participants scanned with 14 scan protocols on 5 MRI scanners!
