Capsulotomy, an ablation technique for OCD, involves heating or destroying small brain tissue areas (3-4mm) and can be helpful with no obvious side effects after recovery.

“you can actually heat the tissue and even destroy it some would say this part of the brain is very safe to destroy it's kind of like an appendix um others would say it's safer to modulate I have seen patients do very well with these ablations and so you know you asked me earlier what what I find so amazing about the brain these effects that we can have sometimes the lack of effect is what's so amazing you can actually Traverse parts of the brain without having any adverse effects on patients function at least that you can test but you can also destroy small parts of the brain we're talking three or four millimeters in size these little ablations can be really helpful for patients but have no obvious side effects that we can tell perhaps after a short recovery from surgery”
