Distribution of the coefficient of variation (CV) at each synapse at Poisson inputs with 10 Hz. Each subfigure Figure

8 depicts the distribution of the CV at the given synapse of both neuron

*A *and neuron

*B* at Poisson inputs mean firing rate 10 Hz

*. *For example, As shown in the leftmost subfigure

shows the variation of CV of synapses from presynaptic neuron

*B* to postsynaptic neuron

*A.* Similarly,

depicts the distribution of CV of synapses from presynaptic neuron

*A* to postsynaptic neuron

*B.* Moreover, the slopes of the mean release probability,

and

, were determined using linear regression analysis and give the slope of CV of

from bin 1 to 150 and bin 150 to 200, respectively. Similarly,

and

give the CV of

from bin 1 to bin 150 and from 150 to 200, respectively. As depicted in all these subfigures, at all the synapses when its around 200 bins, the difference of the CVs of neuron

*A* and neuron

*B* was about 0.001 and time functions of CVs of both neurons were paralleled to each other.
