Fig. 2From: Stochastic synchronization of neuronal populations with intrinsic and extrinsic noiseLimit cycle in a deterministic E-I network with parameters w E E =11.5, w I E =− w E I =10, w I I =−2, h E =0 and h I =−4. Also F(u)=1/(1+ e − u ). (a) Limit cycle in the ( x E , x I )-plane. (b) Trajectories along the limit cycle for x E (t) (solid curve) and x I (t) (dashed curve).Back to article page
