Lyrics

[Verse 1]
Electrodes kiss the angular gyrus, right-side line,
Blanke flips the switch in two thousand two — Nature's headline,
The patient floats above her own reclining frame,
An out-of-body echo calling out her name,
Sense of self slips sideways, drifting through the room —
Ein Geist outside the body, wo bin ich, in diesem Raum?

[Chorus]
TPJ, c'est où je suis,
Wo bin ich — tell me whose mind owns the view,
Angular gyrus bending body and belief,
Temporo-parietal junction, self and other interweave,
C'est toi ou moi, the border keeps shifting through,
TPJ, map my body, now map you.

[Verse 2]
Two thousand five, the full-body trick returns,
Blanke tilts the camera, watches where location turns,
Ionta's two thousand eleven, published bold in Neuron's air,
First-person perspective lives right there,
Stroke the back, project it forward, feel your "I" relocate —
Temporo-parietal junction holds the self-location gate.

[Chorus]
TPJ, c'est où je suis,
Wo bin ich — tell me whose mind owns the view,
Angular gyrus bending body and belief,
Temporo-parietal junction, self and other interweave,
C'est toi ou moi, the border keeps shifting through,
TPJ, map my body, now map you.

[Verse 3]
Saxe and Kanwisher, two thousand three, found it clean —
Right TPJ lights only when you guess what others mean,
False belief, the marble hidden, swapped behind her back,
Lesion the left side — Samson's patients lose the track,
Nat Neurosci, two thousand four, the proof arrived precise:
Damage that hemisphere, theory of mind pays the price.

[Verse 4]
Mars carved the junction with connectivity's fine blade,
Two thousand twelve, Cerebral Cortex, the map remade —
Dorsal cluster dating IPL, the vigilant eye,
Ventral cluster courting default mode, the social sky,
Macaque brains lack that ventral wiring fully grown —
Dis donc, this social patch might be ours alone.

[Bridge]
Circuit breaker, Corbetta's call, two thousand eight,
Right TPJ reorients, resets the attentional gate,
Mitchell says the mentalizing map and attention overlap,
Krall, two thousand fifteen, runs the meta-analysis lap,
Domain-general? Spezialisiert? Niemand weiß es genau —
Un débat sans fin, mon ami, c'est comme ça.

[Chorus]
TPJ, c'est où je suis,
Wo bin ich — tell me whose mind owns the view,
Angular gyrus bending body and belief,
Temporo-parietal junction, self and other interweave,
C'est toi ou moi, the border keeps shifting through,
TPJ, map my body, now map you.

[Outro]
From area five, the body's own address,
Through intraparietal streams that calibrate and guess,
Up to the junction where the bodily becomes another's mind,
Temporo-parietal — c'est la frontière you'll always find,
Wo bin ich, who are you, the question never ends,
TPJ, le pont between oneself and friends.
