Abstract
In this paper I discuss the kinds of dependence relation that philosophers have argued may obtain between neural events and conscious events; between Ns and Cs. Three major candidate relations are constitution, realization, and identity. There are other candidates for the mind/body relation, but these will serve as the major options. Indeed, these are already more than three options, because philosophers do not agree on the best way to understand constitution; still less to understand realization. I argue that dispute is not merely "metaphysical": each candidate has distinct empirical consequences.
