The spectral images, reproduced in neurosurgery journals and textbooks, could be captioned "Beauty and the Beast."
Captured by X-ray and CT scan, the human brain is pierced by a bullet, nail, pool cue or chunk of razor-sharp debris. The intruding object has ripped a jagged vortex of destruction through the brain's gelatinous lobes and forged an even wider path of quivering shock. If the projectile came in hard and fast, shards of broken skull will be scattered through the delicate tissue. The bullet might have ricocheted off bone and tumbled wildly in the cavity, bursting blood vessels and carving uneven holes where, only moments before, healthy brain cells had hummed.
Such havoc, you would think, would put an abrupt end to the brain's rhythmic buzz of activity and extinguish the life defined by its complex inner work-ings. But — as the awakening of Rep. Gabrielle Giffords has demonstrated these last weeks — the human brain can be resilient, capable of withstanding brutish damage and then masterminding its reconstruction.
"I have seen every foreign body in the world pass through the brain, and I never cease to be amazed that some seem to survive and do amazingly well," said Dr. Ian Armstrong, a Century City neurosurgeon, shortly after Giffords was shot.
