Paper Abstract

We study the effect of noise on a generalized mathematical model for small neural-glial ensemble. In deterministic regime, our model predicts long-term potentiation of the postsynaptic neuron as well as various calcium transients in response to the activation of glion via different pathways. Being activated by noise, the presynaptic neuron shows the irregular firing pattern. We consider how the glion (a generic glial cell) moderates the regime of the postsynaptic neuron. We observe the number of noise induced effects, such as different types of post-excitatory behavior of the postsynaptic neuron at small noise intensity and the long-term potentiation of the postsynaptic neuron at some optimal noise intensity.
