Abstract
The realization of local space-time models of retinal processes can be achieved by means of available typical dynamical systems simulation tools (like Simulink) because only a very small number of parallel channels is needed. In short, the aim is to simulate both the time and space dimensions as delay chains, where the travelling signals are available at different points of the delay chain to interact among them. These models provide an interesting and fruitful insight into the neurophysiological processes. For the discrete case, this is equivalent to modelling a generalized shift register, which provides for the transformation of space into time. Thus, a spatial contrast of illumination (e.g. a local spatial pulse of light) is equivalent to a time pulse. For the temporal local modelling (linear and non-linear ON, OFF and ONOFF neurons) we consider the modelling based on the interaction of fast and retarded processes.
