What resolves this contention: Whether prefrontal working-memory delay activity is dominated by sparse transient bursts (Lundqvist/Miller) or by stable persistent attractor activity (Hussar reanalysis) — competing characterisations of the same single-trial PFC spiking data. / On single trials, activity often occurs in sparse transient bursts. / In sharp contrast to the burst-coding model predictions, we only found a small fraction of neurons showing increased WM-de
