Influence of synaptic inhibition and neuronal adaptation on network-based oscillations. A-C: Existence of oscillatory network states (OSC) and corresponding frequencies f as a function of the strength and timescale of synaptic inhibition for networks without adaptation (A), with increased spike-dependent adaptation (B) and increased sub-threshold adaptation (C). Asynchronous network states (ASYN) are indicated by white regions. Arrows mark balance of recurrent excitation and inhibition. On the left the delay distributions (green: excitation, orange: inhibition) corresponding to faster (bottom) and slower inhibition (top) are shown.
