🧠 Scientific Explanation & Psychophysics
Human visual perception processes 3D scenes by connecting local spatial cues (corners, edges, depth gradients). While each individual joint is locally plausible, the brain fails to realize that the global spatial combination is impossible in 3-space.
Why This Works in the Brain
The visual cortex processes incoming sensory information using specialized receptive fields and cortical feature detectors. Illusions occur when mathematical geometries produce conflicting spatial signals, exposing how the brain constructs subjective perception from objective electromagnetic light waves.
