Figure 6.
Probability distribution of the phase difference between a pair of E-I oscillators as a function of extrinsic noise strength σ with g, h given by Fig. 4. Solid curves are based on analytical calculations, whereas black (gray) filled circles correspond to stochastic simulations of the phase-reduced (planar) Langevin equations. (a) N = 105, σ = 0.01. The curve is very flat, showing little synchronization. (b) N = 105, σ = 0.08. Increasing σ causes the curve to have a much sharper peak and much more synchronization.
