Lyrics

[Verse 1]
Nineteen-oh-nine, Bálint watched a man reach blind,
Eyes locked open, psychic paralysis of gaze left behind,
Holmes in nineteen-eighteen drew the second line,
Simultanagnosia — one object swallows all design.
Bilateral parieto-occipital, the back-brain pincer bites,
Posterior cortical atrophy now writes these modern nights.

[Chorus]
Vê mas não alcança — optic ataxia, mão perdida no espaço,
Três sintomas, um abraço — esse é Bálint no meu abraço,
Gerstmann quebra o fio — não é lesão, é desconexão,
Quatro sinais, one wire down, caiu a conexão, caiu no chão.

[Verse 2]
Perenin and Vighetto, nineteen eighty-eight, drew the deeper map,
Superior parietal, intraparietal sulcus — that's the reaching gap.
Karnath and Perenin, two-thousand-five, zoomed to the junction site,
Parieto-occipital border, matching PRR and SPOC just right.
Pisella, two-thousand, moved the target mid-flight, watched the hand,
No quick correction comes — the automatic pilot can't command,
The fingers overshoot the cup, the eye knows but the arm won't land.

[Chorus]
Vê mas não alcança — optic ataxia, mão perdida no espaço,
Três sintomas, um abraço — esse é Bálint no meu abraço,
Gerstmann quebra o fio — não é lesão, é desconexão,
Quatro sinais, one wire down, caiu a conexão, caiu no chão.

[Verse 3]
Gerstmann, nineteen twenty-four, four strangers share one host:
Finger agnosia first — can't name the digit lost,
Agraphia steals the pen, acalculia steals the sum,
Left-right disorientation spins the compass numb.
Left angular gyrus, they said, the single guilty seat,
But Rusconi, two-thousand-nine, found no shared cortical street.

[Bridge]
Four functions, four addresses, never neighbors on the map,
They meet below in white matter, down in the subcortical gap.
Roux confirmed it stimulating — cortex sparking, function stays,
É debaixo, não em cima, o problema são as vias.
Dorso-dorsal grasps the target, ventral streams attend and see,
Left IPL counts and spells — three systems, running separately.

[Verse 4]
Bedside test: count the fingers, copy a cube, name left from right,
Draw a clock — the numbers crowd, the hands dissolve from sight.
MRI shows parietal thinning, PET confirms the hypometabolic sign,
PCA and Bálint overlap — Alzheimer's atypical line.
Treatment's compensation: scanning strategies, structured space,
No cure for the wire, just new paths the mind can trace,
The lesion holds its ground, but the circuits find a different face.

[Chorus]
Vê mas não alcança — optic ataxia, mão perdida no espaço,
Três sintomas, um abraço — esse é Bálint no meu abraço,
Gerstmann quebra o fio — não é lesão, é desconexão,
Quatro sinais, one wire down, caiu a conexão, caiu no chão.

[Outro]
Não é a área, é a estrada — it's the wire, not the ward,
The parietal lobe keeps singing circuits, each one its own chord.
