What resolves this contention: Mechanism of short-term/working memory maintenance: synaptic short-term plasticity (activity-silent) vs reverberatory spiking discrete attractor in cortical recurrent networks. / Here, we propose that working memory is sustained by calcium-mediated synaptic facilitation in the recurrent connections of neocortical networks. / Together our data indicate that frontal cortex networks function as discrete attractors that maintain short-term memories.
