Neuronal activation, output and input to a one-dimensional DF (upper subpanel) and interaction kernel in the field (lower subpanel). (A) DF with no neural peaks, (B) a self-stabilizing peak, (C) history of neural activity in the DF of panel B over time, (D) a self-sustaining peak, (E) multi-peak DF with two peaks, and (F) a winner-take-all DF
