This current is characterized in terms of rates, auto and cross-correlations, and correlation time scale $ au_c$ of excitatory and inhibitory inputs. The output rate $
u_{out}$ is calculated in the Fokker-Planck (FP) formalism in the limit of both small and large $ au_c$ compared to the membrane time constant $ au$ of the neuron. By simulations we check the analytical results, provide an interpolation valid for all $ au_c$ and study the neuron’s response to rapid changes in the correlation magnitude. | Source: | arXiv, cond-mat/0211292 | Other source: | [GID 1142651] pmid12513181 | Services: | Forum | Review | PDF | Favorites |
