Dynamical mean-field theory for a highly heterogeneous neural population with graded persistent activity of the entorhinal cortex
Fig 6
The maximum Lyapunov exponent of the network dynamics.
a: The numerically estimated maximum Lyapunov exponent, averaged over ten realizations of random initial conditions, for the model network as a function of the coupling strength g. Line colors indicate the value of p (from the far-right purple curve for p = 0.0 to the far-left yellow curve for p = 1.0). Dashed vertical lines indicate gc. The number of neurons in the network is fixed at N = 3000. b: The same Lyapunov exponent for different values of N with p = 0.8. Blue, orange, green, and red lines correspond to networks of N = 100, 500, 1000, and 3000, respectively. Error bars show standard deviation.
