p300fig08.12 A single flash activates a Gaussian receptive field across space whose maximum is chosen by a winner-take-all recurrent on-center off-surround network.<BR>||  Gaussian receptive fields are sufficient! (Grossberg, Rudd 1992).  Single flash.  Suppose that a single flash causes a narrow peak of activity at the position where it occurs.  It generates output signals through a Gaussian filter that produces a Gaussian activity profile at the next processing stage.,  A recurrent on-center off-surround network chooses the maximum activity and suppresses samaller activities.  Winner-take-all
