The Visual-Origin Theory of Neural Decussation: A Design-Based Explanation for Contralateral Control
Year: 2025
Type: article
Abstract: The Visual Origion Theory of Neuronal Decussation explains the universal contralateral organization of vertebrate sensory and motor pathways as a direct consequence of light geometry. Rays from the right visual world cross the midline in space before reaching the eyes; the optic chiasm simply preserves this pre-existing crossing, aligning each hemisphere with the contralateral visual hemifield. Motor decussations then follow the same spatial logic to produce rapid, field-coherent action. Alternative wirings are geometrically and temporally inferior and match known human pathologies (achiasma, albinism). VOD offers the first unified, physics-driven account of why vertebrate brains are built contralaterally.
