[Verse 1]
Nineteen eighty-five, a Sheffield room, Anthony Barker holds the key,
A coil above the scalp, no scalpel, no slice, just a jolt the cortex sees.
Magnetic pulse goes rapid, through bone it slips unseen,
Skull's no wall for lightning dressed in a copper sheen.
[Chorus]
TMS, без ножа, sem corte, sem dor,
A pulse through the skull and the cortex wants more,
Магнітний дотик, invisible hand,
Wakes up the motor map, now you understand.
[Verse 2]
Point it over M1, where the hand commands reside,
A twitch lights up the thumb, the MEP's our guide,
Motor evoked potential, millivolt by millivolt,
Size tells us how excitable the corticospinal bolt.
The muscle answers back in a quick electric shout,
Telling us how primed the pathway is, inside and out.
[Chorus]
TMS, без ножа, sem corte, sem dor,
A pulse through the skull and the cortex wants more,
Магнітний дотик, invisible hand,
Wakes up the motor map, now you understand.
[Verse 3]
Now send two pulses, first one soft, the second strong and clear,
Short-interval inhibition quiets what the second would steer.
SICI's its name, a brake pedal built from chemistry,
GABA-A receptors humming the inhibitory melody.
Without that brake, the circuit runs too hot, too wild,
With it tuned just right, the movement stays mild.
[Verse 4]
Repeat it fast as rTMS, excitability bends low or climbs,
Slow pulses quiet neurons, quick ones wake them many times.
Or stream it soft as tDCS, a current thin and slow,
Anode wakes the neurons, cathode makes them go.
Doctors dream of stroke rehab, rebuilding what was lost,
Rewiring silent synapses, whatever the cost.
Será que cura? Can it heal the broken hand?
Клініки full of hope across every land.
[Chorus]
TMS, без ножа, sem corte, sem dor,
A pulse through the skull and the cortex wants more,
Магнітний дотик, invisible hand,
Wakes up the motor map, now you understand.
[Bridge]
Graziano, two thousand two, a monkey's cortex probed,
Not with a flicker but a five-hundred-millisecond load,
Long trains of current pull the hand up to the mouth,
Or fold the arm in a shield, defense facing south.
No twitchy finger map, but something ethological,
Actions sewn into the brain, primordial, logical.
Мавпочка захищається, рука до рота йде,
The motor cortex paints behavior, not just where current lead.
[Chorus]
TMS, без ножа, sem corte, sem dor,
A pulse through the skull and the cortex wants more,
Магнітний дотик, invisible hand,
Wakes up the motor map, now you understand.
[Outro]
Barker's coil, Graziano's trains, a century of spark,
Mapping how the brain behaves, lighting corners once called dark.
Sem corte, без ножа, just a pulse and a plan,
Learn the brain's own language — now you understand.
