Visibility, Visual Awareness, And Visual Masking Of Simple Unattended Targets Are Confined To Areas In The Occipital Cortex Beyond Human V1/V2, Peter U. Tse, Susanna Martinez-Conde, Alexander A. Schlegel, Stephen L. Macknik

Dartmouth Scholarship

In visual masking, visible targets are rendered invisible by modifying the context in which they are presented, but not by modifying the targets themselves. Here, we localize the neuronal correlates of visual awareness in the human brain by using visual masking illusions. We compare monoptic visual masking activation, which we find within all retinotopic visual areas, with dichoptic masking activation, which we find only in those retinotopic areas downstream of V2. Because monoptic and dichoptic masking are equivalent in magnitude perceptually, the present results establish a lower bound for maintenance of visual awareness of simple unattended targets. Moreover, we find …
