  Mathematical model of spiking neuron network (SNN) supplied by astrocytes is
investigated. The astrocytes are specific type of brain cells which are not
electrically excitable but inducing chemical modulations of neuronal firing. We
analyzed how the astrocytes influence on images encoded in the form of dynamic
spiking pattern of the SNN. Serving at much slower time scale the astrocytic
network interacting with the spiking neurons can remarkably enhance the image
recognition quality. Spiking dynamics was affected by noise distorting the
information image. We demonstrated that the activation of astrocyte can
significantly suppress noise influence improving dynamic image representation
by the SNN.
