[Verse 1]
Lateral intraparietal, parked behind your eye,
Watching dots drift leftward while coherence climbs up high,
MT whispers motion, LIP keeps the score,
Firing rate's a tally, climbing more and more.
Shadlen and Newsome clocked the ramp unfold,
Ninety-six, two-thousand-one, the pattern told,
Roitman found the finish line, a common height,
Seventy milliseconds before the saccade takes flight.
[Chorus]
Ramp it up, stack the clicks, reach the bound,
LIP's the ledger where the evidence is found,
Count the dots, climb the slope, cross the gate,
Decide, decide — don't hesitate.
[Verse 2]
Platt and Glimcher, ninety-nine, in Nature they revealed,
Bigger juice meant bigger spikes — value unconcealed,
Sugrue watched the foraging, the matching law in play,
Fractional income steers the neurons' sway,
Kiani offered sure-bets, dangled low-risk gold,
Confidence rode shotgun with the story being told,
High firing, sure of motion, skip the gamble, stay secure,
LIP's not just counting dots, it's weighing if you're sure.
[Chorus]
Ramp it up, stack the clicks, reach the bound,
LIP's the ledger where the evidence is found,
Count the dots, climb the slope, cross the gate,
Decide, decide — don't hesitate.
[Verse 3]
Hanks and Ditterich sent a current through the patch,
Biased choices, shifted timing — watch the circuit catch,
Freedman and Assad trained a category sense,
Not just motion vectors — abstract bins, condensed,
Monkeys sort the pattern into groups, LIP tags it clean,
Abstract thought in spiking form, the subtlest code I've seen.
[Bridge]
But Latimer cried foul in two-thousand-fifteen,
Said the ramp's a blur — a statistical screen,
Maybe neurons leap in steps, a punctate little stair,
Sudden jumps mistaken for a slow continuous flare,
Call it accretion, grain by grain, or one great lurching stride,
The models tie on single trials — the question's open wide.
[Verse 4]
Katz and Yates and Pillow and Huk, two-thousand-sixteen,
Silenced LIP's neurons, yet behavior stayed serene,
Motion choices still intact without the area's light,
Zhou and Freedman narrowed it — the deficit tied to sight,
Only when the target sat inside the blinded field,
Did the muted patch of cortex make the choices yield.
[Chorus]
Ramp it up, stack the clicks, reach the bound,
LIP's the ledger where the evidence is found,
Count the dots, climb the slope, cross the gate,
Decide, decide — don't hesitate.
[Outro]
One node among many, not the only throne,
A distributed network, LIP's not alone,
Necessity shifts with the task and where you stare,
The parietal story's written everywhere.
