BackgroundMonocular enucleation, the surgical removal of one eye, occurs early in life and leads to changes in visual, auditory, and audiovisual processing in adulthood. These changes can be observed behaviorally, as well as through cortical structure and white matter connectivity of visual and auditory pathways. Subcortically, the thalamus is a critical sensory processing structure that modulates both unisensory and multisensory stimuli, which are later processed in the cortex. Previous studies
