Before revision:  For the case of two-dimensional rate units with strong adaptation, we find that the network exhibits a state of "resonant chaos", whose resonance frequency can be predicted from the properties of isolated units .
After revision:  For the case of two-dimensional rate units with strong adaptation, we find that the network exhibits a state of "resonant chaos", characterized by robust, narrow-band stochastic oscillations. The coherence of stochastic oscillations is maximal at the onset of chaos and their correlation time scales with the adaptation timescale of single units. Surprisingly, the resonance frequency can be predicted from the properties of isolated units .
