The results suggest that long‐range interhemispheric binding of ambiguous motion representations mainly reflect bottom–up processes from hMT+ during perceptual state maintenance, in contrast, state transitions maybe influenced by high‐level regions such as the SPL.
Interhemispheric Binding of Ambiguous Visual Motion Is Associated with Changes in Beta Oscillatory Activity but Not with Gamma Range Synchrony

It is revealed that the visual experience of binding can be identified by distinct signatures of oscillatory activity, regardless of long-range gamma synchrony, suggesting that such type of synchrony does not underlie perceptual binding.

A positive association between the synapse-rich inner plexiform layer (IPL) and V1 in AD is identified, which might reflect changes in synaptic function resulting from Aβ deposition, contributing to early visual loss.
