There are some people who we've had to kind of exclude from our trial for having skulls that are too thick or too thin or scalp that's too thick or too thin. I think we have the middle 97% or so of people, but you can't account for all human anatomy variability.

Not too bad. Once you really get used to this, that's where experience and skill and education really come into play. If you stare at a thousand brains... It becomes easier to mentally peel back the, say, for instance, blood vessels that are obscuring the sulci and gyri, the wrinkle pattern of the surface of the brain.

Occasionally, when you're first starting to do this and you open the skull, it doesn't match what you thought you were going to see based on the MRI. And with more experience, you learn to kind of peel back that layer of blood vessels and see the underlying pattern of wrinkles in the brain and use that as a landmark for where you are. The wrinkles are a landmark? Yeah.

So I was describing hand knob earlier. That's a pattern of the wrinkles in the brain. It's sort of this sort of Greek letter omega shaped area of the brain.

Yeah. Where is it? So you have this strip of brain running down the top called the primary motor area. And I'm sure you've seen this picture of the homunculus laid over the surface of the brain, the weird little guy with huge lips and giant hands. That guy sort of...

lays with his legs up at the top of the brain and face arm areas farther down, and then some kind of mouth, lip, tongue areas farther down. And so the hand is right in there, and then the areas that control speech, at least on the left side of the brain in most people, are just below that. And so any muscle that you voluntarily move in your body

The vast majority of that references that strip or those intentions come from that strip of brain and the wrinkle for hand knob is right in the middle of that.
