(a) Temporal course of the membrane potential for a suprathreshold LIF neuron in the absence of synaptic stimuli. The pulses $E_s$ are exactly collocated in correspondence of the firing times. $u_{\mathrm{R}}$ represents the reset value and $u_{\mathrm{th}}$ the threshold value. (b) ‘Raster plot’ for a splay state in a network of $N=100$ neurons: neuron indices are reported as a function of firing times. The dots correspond to the times when the neurons emit an action potential. Indices are ordered according to the (first) time the neurons have reached the threshold.
