To further clarify, I believe the authors are advocating a WM model where an excitatory subnet (activated by a Positive cue) sustains its firing (in the absence of that cue; the Delay period) by activating inhibitors of its own inhibitors. (these inhibitory subnets, like goldenshale mentions, also seem to inhibit excitatory subnets, diffusely). model diagram: https://i.ibb.co/nrh1pVJ/figs.png https://i.ibb.co/nrh1pVJ/figs.png
