Thanks—I meant “formal” as in “formal grammar”, not that it wasn’t described in the published protocol. As in, there’s nothing in the protocol’s explicit form that distinguishes between this implied meaning and a real extra recipient—so it simplifies the parsing but adds an extra post-parsing step.
Between the various cortical layers and white matter, what part of the brain’s structure do these implants typically target? Do they sit on top of the outermost layer of some specific region of the cortex (effectively creating a new layer), or do they make long-distance connections to other brain structures?
