Abstract:Monocular patching improves the non-patched eye in clinical practice, while recent laboratory evidence suggests that short-term patching strengthens the patched eye instead. The neural mechanisms underlying these opposite effects remain elusive. Using high-resolution 7T fMRI, we found two rapid and opposing mechanisms in the visual thalamus and higher visual cortex in response to monocular contrast deprivation (MCD) in human adults. Short-term MCD shifted ocular dominance of BOLD responses in favor of the depr… Show more
