[Verse 1]
Liepmann walked the wards in nineteen-hundred,
watched a hand forget the shape it plundered,
left hemisphere's down, the gesture's gone missing,
not weak, not blind — just the plan stopped listening.
Ideomotor apraxia, he named the ghost,
a message with no sender, an order with no post.
[Chorus]
Praxicon, praxicon, сховано глибоко,
в лівій тім'яній частці — that's where the know-how go.
Heilman found the library, Rothi turned the key,
posterior forgets the plan, anterior forgets to be free,
die Hand weiß es schon, doch die Leitung ist zerbrochen,
Praxicon, praxicon — the gesture left unspoken.
[Verse 2]
Buxbaum drew two rivers running through the skull,
dorso-dorsal's online, shaping grip from pure pull —
both sides pitch together, a mirror-matched machine,
sculpting fingers to a coffee cup, quick and unseen.
But ventro-dorsal's quieter, left side owns the lease,
storing how a hammer swings, a function held in peace,
knowledge of the tool outlives the tool in hand,
semantic grip surviving when the real one's banned.
[Chorus]
Praxicon, praxicon, сховано глибоко,
в лівій тім'яній частці — that's where the know-how go.
Heilman found the library, Rothi turned the key,
posterior forgets the plan, anterior forgets to be free,
die Hand weiß es schon, doch die Leitung ist zerbrochen,
Praxicon, praxicon — the gesture left unspoken.
[Verse 3]
Goldenberg handed strangers tools they'd never met,
wire bent to fetch a token, puzzle freshly set,
damage left parietal, the trick refused to form,
mechanical reasoning needs that cortex to perform.
Peeters watched the monkeys and watched the human eye,
only ours lit anterior supramarginal — why?
Orban called it ours alone, a uniquely human patch,
the spot where watching toolwork finds its only match.
[Verse 4]
Fogassi tracked a neuron in the PFG terrain,
firing at a grasp before the goal was even plain,
reach to eat, it sings one song, reach to place, another tune,
the hand's intention broadcast like a secret platoon.
These cells shake hands with F5, mirror calling mirror back,
understanding action from the opening of the act,
parietal reads the ending written in the start,
intention coded early — a blueprint, not an art.
[Bridge]
Posterior loses words, anterior loses will,
ліва частка пам'ятає every learned tool skill,
zwei Wege, zwei Systeme — use and knowledge, hand in hand,
one is built for grasping, one remembers how we planned.
[Outro]
Praxicon, praxicon, сховано глибоко,
die Hand weiß es schon — the gesture left unspoken,
mirror, tool, and intention, woven in the fold,
parietal lobe's story, quietly retold.
