Two-layer neural field model of the type analyzed by Amari (1977). The model consists of a single layer of feature-selective excitatory neurons reciprocally coupled to a similarly-tuned layer of inhibitory interneurons. Neurons coding for similar values along the metric dimension in the excitatory field engage in locally excitatory interactions (curved solid arrow), and transmit excitatory activation to the inhibitory layer. Neurons in the inhibitory layer transmit broad lateral inhibition back to the excitatory field (dashed arrows). See text for additional details
