Synchronized Oscillations in γ Frequency Band in a Neuronal Network

Synchronous oscillation with frequencies in γ band (30-70 Hz), regarded as relevant to the information processing such as scene segmentation, has been numerically studied in a neuronal network. It is found that this synchronous oscillation relates to an intrinsic oscillation of the system in γ band and this feature is robust to various configurations of external stimuli and couplings.
