A stochastic-field description of finite-size spiking neural networks
Fig 3
Simulation of the SPDE and comparison with the full network dynamics and the mean-field theory for a time dependent stimulus.
A) Time evolution of the stimulus. B) Activity obtained from simulations of the full network. C) Activity obtained from simulations of the mean-field equation (Eq 13). D) Activity obtained from the SPDE (Eq 7). The same initial condition was used in all cases. Parameters are as in Fig 2C, except that N = 500 and Δt = 0.1 ms.
