[Verse 1] Deep in hippocampus where the place cells fire Grid cells map the cortex like a neural choir O'Keefe found the secret in a rat's brain maze Each neuron holds location in its firing phase Tolman saw the vision back in forty-eight Cognitive maps were building what we navigate Not just spatial movement through the world we roam Abstract reasoning finds its neural home [Chorus] Navigate the mind's terrain Grid cells plot the mental plane Successor states predict the flow Where thoughts and memories will go Hexagonal patterns guide the way Through conceptual space we play Reasoning moves like GPS Finding paths through mental mesh [Verse 2] Successor representation holds the key between Model-free reactions and the planning scene States encoded by their future occupancy Place field shapes emerge from this prophecy Stachenfeld mapped the theory to the brain Predictive maps where memories remain Between the reflex and the master plan Lives the code that makes us truly human [Chorus] Navigate the mind's terrain Grid cells plot the mental plane Successor states predict the flow Where thoughts and memories will go Hexagonal patterns guide the way Through conceptual space we play Reasoning moves like GPS Finding paths through mental mesh [Bridge] Constantinescu found the smoking gun Grid codes fire when concept work gets done Humans navigate through abstract space With hexagonal signals we can trace Tolman-Eichenbaum machine divides Structure scaffold from content that hides Factorizing what from where Reusable maps that transfer everywhere [Verse 3] Transitive inference jumps from A to C Trajectory finding sets the logic free Behrens unified the spatial and conceptual dome Every reasoning path leads the long way home Replay sequences plan tomorrow's moves Mattar showed priority's neural grooves From rat maze running to the deepest thought Same machinery that evolution brought [Verse 4] In the entorhinal cortex layers deep Theta rhythms rock while neural patterns sweep Social hierarchies map to spatial code Status relationships follow grid node road Time itself gets structured in this neural space Sequences unfold with grid cell's steady pace From bird migration to our abstract dreams Navigation's more than what it seems [Final Chorus] Navigate the mind's terrain Grid cells plot the mental plane Successor states predict the flow Where thoughts and memories will go Hexagonal patterns guide the way Through conceptual space we play Reasoning moves like GPS Finding paths through mental mesh Cognitive maps light neural fires Abstract navigation never tires
