eLife Assessment This work provides an important and novel framework for interpreting the interactions between recurrent dynamics across stages of neural processing. The authors report that two different kinds of dynamics exist in recurrent networks differing in the extent to which they align with the output weights. The authors also present convincing evidence that both types of dynamics exist in the brain.

Highlights We examine how the structure in neural activity and connectivity is related to the computations a network performs. We distinguish two general types of structure that we term geometry and modularity. Geometry and modularity can be determined both at the level of neural activity or connectivity. We harness these concepts to synthetically review recent modeling works on three classes of computations.
