[Verse 1] Beyond the bars and edges that we know so well V1's got secrets, more stories to tell Spatial frequency sorts the coarse from fine Rough bark from silk, each texture's divine Some neurons love the details, crisp and tight Others prefer the blur, the broader sight [Chorus] Five dimensions dancing in your visual cortex Spatial frequency, motion, depth connects Binocular disparity brings the world alive Color blobs and end-stopping help us thrive V1's not just orientation, there's so much more Five feature filters at the neural core [Verse 2] Motion detectors catch the leftward flow Magno-driven cells know which way things go Direction selective, they fire with precision Up, down, diagonal - each has its mission While stationary patterns leave them cold Moving targets make their stories unfold [Chorus] Five dimensions dancing in your visual cortex Spatial frequency, motion, depth connects Binocular disparity brings the world alive Color blobs and end-stopping help us thrive V1's not just orientation, there's so much more Five feature filters at the neural core [Verse 3] Two eyes diverge but V1 makes them one Binocular disparity's where depth's begun Left eye, right eye, slightly different views This tiny shift gives stereoscopic clues First cortical stage where the eyes combine Turning flat pictures into depth divine [Verse 4] Hypercolumns organize this neural maze Each contains the maps that guide our gaze Orientation columns spinning all around While ocular preference keeps eyes unbound Six layers deep in cortical design Simple, complex cells in ordered lines [Bridge] Cytochrome oxidase blobs light up the scene Processing color in patches of protein Red, blue, and yellow find their neural home While end-stopped cells won't let long bars roam Fire for short lines but shut down when extended Curvature detection, context blended [Chorus] Five dimensions dancing in your visual cortex Spatial frequency, motion, depth connects Binocular disparity brings the world alive Color blobs and end-stopping help us thrive V1's not just orientation, there's so much more Five feature filters at the neural core [Outro] From texture maps to motion's flow From stereo depth to color's glow End-stopping curves complete the show V1's dimensions help us know [Final Chorus] Five dimensions dancing in your visual cortex Spatial frequency, motion, depth connects Binocular disparity brings the world alive Color blobs and end-stopping help us thrive V1's not just orientation, there's so much more Five feature filters at the neural core
