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?
