It's called Trans Cranial Magnetic Stimulation, or TMS.

So allometric cranial ontogeny is relative skull growth.

Ideally you want to put the head support in the cranial area, right there.

The comprehensive solution this is the device it's about one inches by two inches and, oddly enough, just the thickness of most cranial bones.

We formed a company called NeuroPace and we started work on responsive neurostimulation, and this is a picture of what the device looked like, that's placed into the cranial bone.

There's a cut made in the scalp it's opened the neurosurgeon has a template he marks it around, and uses a dental burr to remove a piece of the cranial bone exactly the size of our device.
