Sure it does: the sub-human conscious experience of a paramecium is what it's like to /be/ the part of the universe comprising the paramecium. Although that part of the universe is as much a paramecium as the part that's human is human, so I don't think what's going on there is 'sub' human. That said, there's less complexity there, so it seems like being that part of the universe would be less 'interesting'--but then again, that's just a human value judgement and probably similarly irrelevant to the universe and paramecia. Neurons aren't central to what I'm talking about; I'm just applying something like a variant of the panpsychic hypothesis to the human situation.
DNA is a complex language, it's words are chemical signals and it exists in a soup formed of mineral and organic stuff. I think even a paramecium has quite a lot more complexity than we give it credit for. We also know that cells talk to each other by electrical and chemical signaling, so there is that external language besides the internal one.
