... By "neuronal", we're talking "actual, live brain cells", by the way.

Presumably, these cells they're using don't have any microtubulary structures contained in those life support dishes, hence there would be no way for them to create anything even approximating the quantum-modulated engram/EM hologram making up an individual consciousness as we have come to understand it

I would bet my left nutsack there's more than one AI black lab working on an upscaled brain-sized version of this already though
