Title: 
Response of Spiking Neurons to Correlated Inputs

Authors:
Ruben Moreno, Jaime de la Rocha, Alfonso Renart and Nestor Parga


Abstract:

The effect of a temporally correlated afferent current 
on the firing rate of a leaky integrate-and-fire (LIF) 
neuron is studied. This current is characterized in 
terms of rates, auto- and cross-correlations, and 
correlation time scale Tc of excitatory and inhibitory 
inputs. The output rate is calculated in the Fokker-Planck 
formalism in the limit of both small and large Tc 
compared to the membrane time constant of the neuron. 
By simulations we check the analytical results, provide 
an interpolation valid for all Tc and study the neuron's 
reponse to rapid changes in the correlation magnitude.
