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

Thread below! 👇 ImageImageImageImage 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.
