Figure 7. Relation between the Inline graphic frequency-scaling exponent and that measured from the Fano Factor (FF) of the output spike train.

Figure 7

A Example of the FF changes as a function of time bin, for different input parameters Inline graphic. The resting potential Inline graphic has been set to −60 mV to ensure a large enough number of spikes. The synchrony parameter is fixed at 6%. B Relation between spiking and relative Inline graphic frequency-scaling exponents for different resting potentials (Inline graphic = −65 mV, −62.5 mV and −60 mV). C,D Fano Factor frequency-scaling exponents as a bivariate function of excitatory and inhibitory Inline graphic and Inline graphic parameters, in the absence of excitatory-inhibitory correlation and for and Inline graphic −65 mV (C), and in the case of 40% of correlation and Inline graphic −62.5 mV (D). In this latter case, Inline graphic has been increased by a few mV to ensure a reasonable level of spiking activity.
