nnmt.lif._general._mean_input¶

nnmt.lif._general._mean_input(nu, J, K, tau_m, J_ext, K_ext, nu_ext, I_ext=None, C=None)[source]¶

Calc mean input for lif neurons in fixed in-degree connectivity network.

Following Eq. 3.4 in Fourcaud and Brunel [2002].

Parameters:

nunp.array: Firing rates of populations in Hz.
Jnp.array: Weight matrix in V.
Knp.array: In-degree matrix.
tau_m[float | 1d array]: Membrane time constant of post-synatic neuron in s.
J_extnp.array: External weight matrix in V.
K_extnp.array: Numbers of external input neurons to each population.
nu_ext1d array: Firing rates of external populations in Hz.
I_extfloat, optional: External d.c. input in A, requires membrane capacitance as well.
Cfloat, optional: Membrane capacitance in F, required if external input is given.

Returns:
