Description:
The problem of the genesis of oscillatory phenomena in a continuous distribution of excitatory and inhibitory neurons is addressed by introducing a neural field model of reaction-diffusion type. The presence of the diffusive term, combined with the nonlinear point interactions allows the system to exhibit cooperative activation properties in space and time. A detailed analysis of the resulting oscillatory behaviour of the model evidences its capability of generating stimulus-induced spatio-temporal coherence fields, similar to the ones experimentally observed in the mammalian visual cortex. The perceptual role of the attendant association fields, as flexible mediums to establish feature association in the visual space, is discussed
