You electrically stimulate around the spot with a probe where you’re planning to resect. If the patient can’t perform whatever task you’re evaluating then you know you can’t resect in that area. Generally looking for a 1cm margin between tissue you’re going to resect and a positive stim site.
Can’t undo brain cuts. CNS neurons don’t repair themselves like peripheral neurons or your skin. Generally not cutting glioma brain tumors out per se more likely to use ultrasonic aspiration to suck the tumor out piecemeal. Depends on the tumor though.
- SeanAnderson 4y agoOh, that makes sense. Cool that we can "dry run" explore with electric pulses! Thanks for explaining :)
- infogulch 4y ago"dry run" is a great analogy!
- elteto 4y agoFascinating! What is ultrasonic aspiration and how does it work?
- amelius 4y agoHow do you know what task to evaluate? And what if this was not a saxophone player, but a tennis player? Or both?
- Firmwarrior 4y agoThe worst is when you're performing brain surgery on a brain surgeon. The operating theater can get really crowded.
- cfu28 4y agoOperating theater overflow :)
- guynamedloren 4y agoOkay, this was a good one!
- rurban 4y agoWith our brain surgery robot the brain surgeon can definitely perform brain surgery on himself. Or invite a fellow brain surgeon over the phone, well a tablet might work better. Or better VR 3d glasses.
- ayewo 4y agoYou seem knowledgeable about the topic. I'm also curious as to the answer to this question [1]. Why does left-handedness make brain surgery slightly more complicated? 1: https://news.ycombinator.com/item?id=33215614 https://news.ycombinator.com/item?id=33215614
