Yes, SED can be altered through perceptual learning~
Did you know that ~70% of the normal population have some degree of eye dominance? We use this term loosely here, but refer specifically to the a mysterious imbalance in how V1 treats the two eyes' inputs. In our latest IOVS paper, we look for the optimal protocol and show that training under certain conditions can lead to a re-balancing of the inputs. Check out our latest work with our very own KY Kam!
