Isolation and control of the effect of synchrony on the free membrane potential statistics.

A,B Adjusted common input fraction (A) and input firing rate (B) for different values of (gray coded) that ensure the same variance and covariance as for . C Correlation coefficient normalized by between the free membrane potential of a pair of neurons using the adjusted common input fraction . D Standard deviation of the free membrane potential, using the adjusted firing rate . The statistics of the free membrane potential measured in simulations in panels C and D are further verified via (6) and (5) (solid lines).
