There is a recent preprint on the arXiv about defining consciousness with a so called Integrated Information Theory. Will this be relevant to the study of neuronal networks in vitro? It was not straightforward from the manuscript how we can quantify the postulated requirements in our systems. For example, how can we calculate $\Phi^\rm{max}$ for a cultured network with limited number of neurons? Or, what about a simulated network in silico?

The arguments presented in the manuscript seem moving. This can even be a close approximation to the real thing if there is indeed. However, the hit is not strong that will make one feel right on. All the elaboration also creates distance from acceptance. But, can there be anything better?
