A lateral-inhibition type neural field model with restricted connections is
presented here and represents an experimental extension of the continuum neural
field theory (CNFT) by suppression of the global inhibition. A modified CNFT
equation is introduced and allows for a locally defined inhibition to spatially
expand within the network and results in a global competition extending far
beyond the range of local connections by virtue of diffusion of inhibition. The
resulting model is able to attend to a moving stimulus in the presence of a very
high level of noise, several distractors or a mixture of both.
