“Ignition” phenomena in random nets

摘要: The spread of excitation in a “random net” is investigated. It shown that if the thresholds individual neurons net are equal to unity, positive steady state will be reached γ, which previously had been computed as weak connectivity net. If, however, greater than either no exists, or two such states depending on magnitude axone density. In latter case smaller unstable and hence resembles an “ignition point” If initial stimulation (assumed instantaneous) exceeds point,” eventually assumes state.
