From Deafness to Peripheral Vision — And From Patch to Punch

From Deafness to Peripheral Vision — And From Patch to Punch. Hook: PNAS study finds early deafness drives visual cortex to allocate more resources to peripheral vision. Auditory cortex recruited for visual processing. Bridge: Adult brain retains competitive plasticity — same mechanism treats amblyopia without patching. Century-old occlusion therapy has miserable compliance. Dichoptic training balances input: high-contrast Gabor to amblyopic eye, reduced to fellow eye. Brain fuses, suppression lifts, acuity/stereopsis improve. AmblyoPunch packages this as Quest VR game: punch coins, dodge spikes, 4 stages. https://www.meta.com/en-gb/experiences/amblyopunch/1239507485902689/
