Extended Data Fig. 3: Binning affects noise correlations and inference.
From: Systematic errors in connectivity inferred from activity in strongly recurrent networks
a, Noise correlations between neuron pairs (top: full matrix, bottom: superposed rows) for binned vs unbinned spikes from the ring network. The optimal bin-width groups causally related spikes together, and noise correlations at an intermediate r then reflect underlying weights. b, Inference error using inverse Ising with MPF on spike data binned at different widths. c, Fraction of spikes discarded when binarizing binned spike data for Inverse Ising inference.
