[Verse 1] Your eyes ain't cameras clicking frames in sequence neat Vision's more like jazz musicians trading riffs they meet Lower neurons catch the edges, corners sharp and small While higher brain cells dream of faces, shapes that never fall It's hierarchical prediction on a graph that bends and flows Not some factory line assembly, more like how a river knows [Chorus] Feedforward carries evidence ascending like the blues Feedback drops predictions down with attentional cues Small receptive fields below catch details fleeting fast Large receptive fields above hold memories that last It's the interaction where the magic happens true Recurrent graph computing everything you view [Verse 2] Down in V1 they're encoding spatial frequency high Local patches, rapid changes, movements of the eye Up in temporal cortex dwelling sit the abstract kings Invariant to transformation, recognizing constant things Your grandma's face stays grandma's face from near or far away 'Cause higher levels learned the rules that never seem to sway [Chorus] Feedforward carries evidence ascending like the blues Feedback drops predictions down with attentional cues Small receptive fields below catch details fleeting fast Large receptive fields above hold memories that last It's the interaction where the magic happens true Recurrent graph computing everything you view [Bridge] When you spot a friend approaching through the crowded street Bottom-up meets top-down signals where the pathways meet Prediction error drives the learning, updates what you know Attention amplifies the signal, makes important features glow This ain't no simple bottom-up conveyor belt design It's bidirectional conversation, your predictive mind [Verse 3] Fast-changing information travels upward seeking home Slow invariant properties drift down like honeycomb Context shapes perception through those feedback highways wide While feedforward pathways carry sensory data's ride The cortical hierarchy builds reality complete Through recurrent computations, making vision so elite [Chorus] Feedforward carries evidence ascending like the blues Feedback drops predictions down with attentional cues Small receptive fields below catch details fleeting fast Large receptive fields above hold memories that last It's the interaction where the magic happens true Recurrent graph computing everything you view [Outro] So next time that you're seeing, remember what's at play Hierarchical prediction guides you through your day Not a camera, not a scanner, but a graph that thinks and learns Through feedforward, feedback cycles, how your vision discerns
