Interspike interval correlations in neuron models with adaptation and correlated noise
Fig 4
Pattern of interval correlations for the adaptive LIF model.
The PRC Z(τ) and SCC ρk for two different cases that are strong ν < 0 A and weak adaptation 0 < ν < 1 B are shown. In both cases the colored noise correlation time τη is gradually increased. For small correlation times the SCC is governed by the adaption as the colored noise becomes essentially white (dark line and circles). In the other limit of long correlation times the SCCs are positive and governed by the colored noise (light line and circles). For intermediate time scales the SCCs are determined by both processes equally as shown in Fig 3. Parameters (A, B): γ = 1, μ = (20, 5), τa = 2, Δ = (20, 2), σ2 = 0.1, D = 0 and resulting T* = (0.67, 1.04).
