Below are plots of the spike trains (i.e., the timing of when neurons fired in the model). In either case, Neuron1 & Neuron4 are the excitatory neurons, Neuron2 & Neuron5 are the PV interneurons and Neuron3 & Neuron6 are the SST interneurons.
This is the time-course if there is no recurrent connection between neurons one and four:

Whereas this is the time-course if there is a recurrent connection between neurons one and four:
