Lyrics

[Verse 1]
Lateral surface, let's map it slow —
Superior, middle, inferior frontal row,
Precentral gyrus, motor homunculus lives,
Postcentral strip is where sensation gives.
Supramarginal crowns the Sylvian end,
Angular gyrus curves where reading bends,
Pars opercularis, triangularis too,
Orbitalis rounding out the frontal view.

[Chorus]
Мозкова кора — cortex of the mind,
Читай МРТ, кожна борозна знайдена,
Omega sign, hand knob, середина,
Кора кора — function by design,
Resect without a map, you're cutting blind,
Sulci speak if you know how to find.

[Verse 2]
Axial MRI — hunt the central sulcus down,
Omega hand knob, that's your midline crown,
Pars bracket sign and the superior frontal cut,
Bifid postcentral, thin gyrus — read the rut.
Sylvian fissure splits in stem and ramus three,
Anterior horizontal, ascending, then posterior free,
Arachnoid planes give you the surgical seam,
Split the fissure carefully — that's the neurosurgeon's dream.

[Chorus]
Мозкова кора — cortex of the mind,
Читай МРТ, кожна борозна знайдена,
Omega sign, hand knob, середина,
Кора кора — function by design,
Resect without a map, you're cutting blind,
Sulci speak if you know how to find.

[Verse 3]
Broca speaks in pars opercularis,
Wernicke listens past the Sylvianaris —
Arcuate fasciculus strings the two together,
Sever that arc and conduction fails the tether.
Dominance isn't guessed — fMRI, Wada test,
Magnetoencephalography maps the rest.
SMA syndrome — akinesia, mutism, contralateral side,
Recovers in weeks, supplementary motor ride.
Frontal eye fields push the gaze away,
Lesion there, the eyes will stray astray.

[Bridge]
Медіальна поверхня — cingulate, paracentral lobe,
Calcarine sulcus holds the visual strobe,
Cuneus above, lingual gyrus below,
Retinotopic cortex runs a pole-to-pole show.
Macular fibres flare to the occipital tip —
Spare the pole, spare the macula's grip.
Базальна — gyrus rectus, olfactory groove,
Parahippocampal, uncus, fusiform move.
Insula tucked behind the circular seam,
Putamen neighbour, extreme capsule between.

[Verse 4]
Hippocampus — head with digitations curled,
Body, tail, subiculum, dentate unfurled,
Fimbria leads to the choroidal fissure's crease,
Inferior choroidal point — temporal horn's release.
Parietal cortex — neglect lives on the right,
Gerstmann's quartet: acalculia, agraphia's plight,
Finger agnosia, left-right confusion sewn —
Angular gyrus dominant — remember, carve it known.
Apraxia when the praxis maps dissolve,
Every gyrus has a deficit to solve.

[Chorus]
Мозкова кора — cortex of the mind,
Читай МРТ, кожна борозна знайдена,
Omega sign, hand knob, середина,
Кора кора — function by design,
Resect without a map, you're cutting blind,
Sulci speak if you know how to find.

[Outro]
Карта кори — the atlas and the patient disagree,
So map intraoperatively,
Every sulcus earns its name at the table's edge —
Знай кору — cortex knowledge is the surgeon's pledge.
