I believe consciousness is a primarily intracellular, not intercellular process; though it does seem cells synchronize, even across organisms. I believe every cell thinks, but nerve cells are more specialized. This isn’t just what I choose to believe, we have significant and growing evidence that this is the case. And it is clear, many parts of the body think, when you consider the extremely sophisticated tasks it performs without your conscious thought or engaging the brain at all, even though computation and perhaps even reasoning is required.
