Mathematical Simulation and Investigation of the Phenomenon of Coherent Resonance in the Brain

摘要

We numerically modulate one- and multilayer network consisting of Rulkov neurons coupled to each other by chemical coupling, coupling strength was chosen randomly from some area of values. Couplings inside each layer are excitatory, but between layers a part of couplings are inhibitory and another one is excitatory. We discover the phenomenon of formation of space-time structures and investigate the influence of such parameters as network size, number of stimulated neurons, part of inhibitory couplings between layers and amplitudes of external stimulus and internal noise on it. We discover the phenomenon of coherent resonance depending from the parameters.
