nnmt.lif.exp._cvs_single_population(nu, mu, sigma, V_0_rel, V_th_rel, tau_m, tau_s)

Coefficient of variation of interspike intervals for single population.

The original formula is taken from Brunel [2000] Appendix A.1. However, implementing this formula naively is a numerically unstable approach. We first need to rewrite the integral. You find the integrals used here in Layer et al. [2023].

Parameters:

nunp.array

Firing rates of populations in Hz.

mu[float | np.array]

Mean neuron activity in V.

sigma[float | np.array]

Standard deviation of neuron activity in V.

V_0_rel[float | np.array]

Relative reset potential in V.

V_th_rel[float | np.array]

Relative threshold potential in V.

tau_m[float | 1d array]

Membrane time constant of post-synatic neuron in s.

tau_sfloat

Pre-synaptic time constant in s.

Returns:

[float | np.array]

Estimate of coefficients of variation.
