Influence of temporal structure on pairwise spike correlations. (A) Spike cross correlations ν_cond,ij(τ) and auto correlations ν_cond(τ) for three voltage correlation functions C_i(τ). (B) Voltage correlations $C_1(\text{τ})={\text{σ}}_V^2\text{cosh}{(\text{τ}/{\text{τ}}_s)}^{-1}$ (blue), $C_2(\text{τ})={\text{σ}}_V^2\cosh {(\text{τ}/(\sqrt{2{\text{τ}}_s}))}^{-1}\cos (\text{τ}/\sqrt{2{\text{τ}}_s})$ (red), $C_3(\text{τ})={\text{σ}}_V^2[\exp (-{\text{τ}}^2/(6{\text{τ}}_s^2))-{\text{τ}}^2/(\text{3}{\text{τ}}_s^2)\exp (-{\text{τ}}^2/(6{\text{τ}}_s^2))]$(black). Note, all voltage correlations C_i(τ) share the same correlation time τ_s but have a different functional form. (C) ρ_ij vs. T for voltage correlation functions C_i(τ). For all figures the correlation time τ_s = 10 ms, ν = 5 Hz, ν = ν₁ = ν₂; circles denote the corresponding simulation points.
