Multiple neuroimaging and electrophysiological studies confirm that illusory contour perception is mediated by neural processing and completion mechanisms across visual cortical areas.
The retrieved papers provide robust evidence from single-unit recording, fMRI, and electrophysiology demonstrating that visual cortical areas (such as V1, V2, and higher visual areas) represent and process illusory contours through neural completion and feedback mechanisms. None of the papers refute the claim, leading to a SUPPORTED verdict.
