Networks of neurons in the brain are collectively capable of exhibiting a variety of interesting dynamical phenomena. The network’s dynamics can be quite complicated, involving correlations across the neurons in the network and across time. The correlation may not be obviously related to the architecture of the network itself. One of the challenges in neuroscience is to develop a language which can be used to parsimoniously describe these complicate dynamics, that is to say, a way of systematically coarse-graining the network. In this talk I will briefly review some of standard methods for coarse-graining and highlight the regimes for which they fail, then I will also introduce some recent approaches that we have tried, as well as possible direction for future works.
