[Verse 1] Picture two compasses steering where your eyes will land Dorsal stream runs IPS, superior parietal, FEF in command That's goal-directed searching, you picked the target, you're the aim But something flickers unannounced, off to the side, unclaimed Ventral network answers — TPJ and frontal cortex pounce Right hemisphere mostly, breaking focus, forcing a bounce [Chorus] Dorsal plots the path you chose, ventral rings alarm for the unknown Corbetta and Shulman drew the switch back in 2002, now it's carved in bone IPS and SPL steer the ship, TPJ taps the brake Two networks trading the wheel — attention's give and take [Verse 2] Frontoparietal control, Vincent and Dosenbach drew the frame IPL shaking hands with lateral prefrontal, running the game Not fixed wiring — think of it as rented office space Cole's sixty-four tasks proved the hubs rearrange their face Flexible connectivity, same address, different costume each time Switching partners task to task, parietal keeping the rhyme [Chorus] Dorsal plots the path you chose, ventral rings alarm for the unknown Corbetta and Shulman drew the switch back in 2002, now it's carved in bone IPS and SPL steer the ship, TPJ taps the brake Two networks trading the wheel — attention's give and take [Verse 3] Yeo carved a thousand brains into seven, then seventeen domains Parietal scattered thin — dorsal, control, default remains Somatomotor strip and ventral attention share the lobe's estate Margulies drew a gradient, sensory anchored at one gate Angular gyrus and posterior cingulate crown the transmodal rim Farthest from the senses, where abstraction grows its limb [Verse 4] Van den Heuvel found a rich club — superior parietal, precuneus shake hands Trading heavier traffic than the rest of the networked lands Buckner noticed something darker: hubs that labor overtime Gather amyloid plaques early, default's backbone first in line [Bridge] Zoom in closer — Braga, Buckner, Gordon found it's finer than it seems Averaged brains just blur the picture, single scans reveal the seams Interdigitated ribbons woven through the IPL and precuneal skin Your parietal map is yours alone — precision lets us in [Chorus] Dorsal plots the path you chose, ventral rings alarm for the unknown Corbetta and Shulman drew the switch back in 2002, now it's carved in bone IPS and SPL steer the ship, TPJ taps the brake Two networks trading the wheel — attention's give and take [Outro] Hubs reconfigure, gradients climb, rich clubs hum beneath the skin Seven networks, one parietal home — precision lets the whole truth in
