“…Here, however, noise does not actually affect the pathways themselves, so the main features of system response are preserved. We have also recently studied [45] what happens if the presynaptic neuron receives a noisy stimulus rather than constant excitatory input. In this case, the neurons produce an irregular sequence of spikes, and the complex dynamical responses of the model are washed out, but the activation and response pathways remain in charge of the produced patterns.…”
