Using a novel statistical estimator and theoretical modeling, both developed in the framework of maximum entropy models, we reveal highly structured CA1 cell-cell interactions in male rats during open field exploration. The statistics of these interactions depend on whether the animal is in a familiar or novel environment. In both conditions the circuit interactions optimize the encoding of spatial information, but for regimes that differ in the informativeness of their spatial inputs. This structure facilitates linear decodability, making the information easy to read out by downstream circuits. Overall, our findings suggest that the efficient coding hypothesis is not only applicable to individual neuron properties in the sensory periphery, but also to neural interactions in the central brain."}],"oa":1,"year":"2023","volume":43,"date_published":"2023-11-29T00:00:00Z","quality_controlled":"1","pmid":1,"scopus_import":"1","title":"The structure of hippocampal CA1 interactions optimizes spatial coding across experience","intvolume":"        43","citation":{"ista":"Nardin M, Csicsvari JL, Tkačik G, Savin C. 2023.
