There is excitement about the use of synaptic wiring diagrams, or connectomes, for modeling neural computation, but there is also concern that the information a connectome provides is not sufficient to meaningfully constrain a model. My group has made efforts to understand the capabilities and limitations of this kind of data. I will describe a new method for identifying symmetries in connectome data that are suggestive of computations involving representations of variables of interest to an animal, such as ring or toroidal attractors. I will also describe a theory we have developed that characterizes the solution spaces of connectome-constrained recurrent networks and predicts when such networks exhibit degeneracies or unique solutions.
