  "text": "What resolves this contention: The Compte–Brunel–Wang–Wang line-attractor model requires structured, fine-tuned recurrent E/I connectivity for stable persistent activity, whereas Barak et al. show that a randomly connected chaotic network can perform the same parametric WM task and match aspects of monkey PFC data without that structure. / To observe stable spontaneous and persistent activity, we find that recurrent synaptic excitation should be primarily mediated by NMDA receptors, and that overall recurrent synaptic interactions should be dominated by inhibition. / The random network does a surprisingly good job of both performing the task and matching certain aspects of the data.",
