How do neurosurgeons get to the middle of someone’s brain without damaging other parts of the brain?
In: Biology
In short, they don’t.
Detailed imaging (pre-op MRI and intro-operative CT) are often used to create a robust surgical plan which includes trajectories, burr hole locations, and implant targets to minimize risk of bleeding, damage to important speech regions, etc. Unintended cognitive, personality, speech, and motor symptoms are not uncommon following major neurosurgery.
