How do neurosurgeons get to the middle of someone’s brain without damaging other parts of the brain?

Answer 1

Going inside the brain is a last case scenario. In those cases the alternative to surgery is death or a great worsening of the patients QoL. So, rewards outweigh the risks in those cases. Damage does happen, and it is sometimes severe, but it’s all dependent on the result. If going inside your brain meant possible vision loss in your left eye but also meant the removal of a lethal tumor, you’d likely say yes.

Of course, brain surgeons are highly trained in what areas of the brain do what and the ways to do the least damage possible.
