Scheme of neurons and connections in the reduced model. Currents \(I_{1} (t)\) and \(I_{2} (t)\) represent external depolarizing step currents injected to the two dINs to mimic sensory input. Both currents have the same duration d and amplitude A. The current pulses for \(I_{1} (t)\) and \(I_{2} (t)\) are initialised at time \(t_{1}\) and \(t_{2}\), respectively (see Sect. 3.1 for details)
