>Two barely-there lines above the outer edges of her eyebrows mark where surgeons screwed a halo apparatus to Anya's skull to keep her head from moving while they destroyed tiny bits of her brain.
>he remembers being sedated, but not completely out, lying on her back on the scanner table. A special helmet fixed to her head beamed high-intensity ultrasound waves at a targeted brain circuit. When the waves intersected at the desired spot, tissue was ablated - burned away like kids using a magnifying glass and the sun's rays to scorch dead leaves.
>These aren't the "ice pick through the eye socket" lobotomies of the postwar 1940s and '50s. With magnetic resonance guided focused ultrasound capsulotomy - Anya's surgery - there are no burr holes in the skull. No opening of the cranium, no cutting into the brain, no blood. The helmet-like device surgeons placed over her scalp that January day in 2019 is lined with more than 1,000 ultrasound transducers that emit acoustic waves at frequencies far higher than humans can hear.
>Once converged on the target brain circuit, tissue is heated to 60C - a thermal dose sufficient to melt away brain cells and interrupt what scientists have hypothesized is scrambled, hyperactive circuitry within brain networks.
>The brain lesions are tiny, about seven to 10 millimetres, maybe a quarter-inch in diameter, though destroying any bits of a healthy brain is ethically thorny.
