Active decorrelation is dependent on the firing rate. a Membrane potential (Vm) of two simulated sample neurons (gray and blue) for 3 cycles of motor behavior in a recurrent topology model (inset). The dashed line indicates low–pass filtered Vm used for correlation analysis below. b Fast correlation between traces in a vs. time has a clear rhythm, i.e. dependence of firing rate. Sample pair (gray) and population average (blue). c Histogram of correlation between fast correlation and Vm indicates anti–phase (negative correlation, green) compared with shuffled data (gray). d No anti–phase relation between fast correlation and Vm was apparent in experimental measurement (green, n = 17 pairs, 34 correlations) i.e. not significantly different from shuffled distribution (gray, Kolmogorov Smirnov test)
