Figure 8.

A temporal sequence of inputs creates a spatial pattern of activity across item chunks in an Item-and-Order working memory (height of hatched rectangles is proportional to cell activity). Relative activity level codes for item and order. A rehearsal wave allows item activations to compete before the maximally active item elicits an output signal and self-inhibits via feedback inhibition to prevent its perseverative performance. The process then repeats itself. Solid arrows denote excitatory connections. Dashed arrows denote inhibitory connections.
