[Verse 1] Watch her hand, it's strong as ever, grip test perfect, nothing's wrong But ask her "wave goodbye" or "comb your hair" and the gesture's gone It's not the muscle, it's the message lost between the thought and hand Ideomotor apraxia — Liepmann mapped where it began Left parietal cortex, or the premotor strip nearby Damage there steals the skilled plan, though the strength still says "I'll try" [Chorus] Upper neuron: tight and twitchy, reflexes jumping, toes fan wide Babinski curling like a question mark on the sole's underside Lower neuron: soft and shrinking, muscles flicker, strength denied Spasticity up top, flaccid down below — that's your motor neuron guide [Verse 2] ALS won't pick a side, it hunts the whole relay at once Cortex neurons, spinal neurons, both go down — a double blunt So the signs collide and tangle, stiff knee next to withered hand One side screaming hyperreflex, other wasting, barely stand Fasciculations ripple underneath the skin like static hum Mixed-sign riddle for the clinic: upper and lower, both struck dumb [Chorus] Upper neuron: tight and twitchy, reflexes jumping, toes fan wide Babinski curling like a question mark on the sole's underside Lower neuron: soft and shrinking, muscles flicker, strength denied Spasticity up top, flaccid down below — that's your motor neuron guide [Verse 3] Dystonia twists the posture, cramping networks gone astray Basal ganglia tangled up with cerebellar feedback play Essential tremor hums a cousin circuit, quieter, more steady Cerebellar-thalamic wiring shakes the teacup when it's ready Different glitch, different rhythm, both are born below the crown Not the muscle, not the nerve out — it's the circuitry breaking down [Bridge] When the last synapse goes silent, and the body won't obey Locked inside a mind still burning, thoughts with nowhere left to play Electrodes catch the whisper where the motor cortex speaks Brain-computer bridges built for those who've lost their final streaks ALS patients leading — pioneers of silent will Turning thought alone to cursor, proving mind is moving still [Chorus] Upper neuron: tight and twitchy, reflexes jumping, toes fan wide Babinski curling like a question mark on the sole's underside Lower neuron: soft and shrinking, muscles flicker, strength denied Spasticity up top, flaccid down below — that's your motor neuron guide [Outro] Strength intact but gesture missing — call it apraxia's maze Upper tight and lower flaccid — ALS's double blaze Basal ganglia twist, the cerebellum shivers thin That's the brain in all its breakdown, and the mind still locked within
