Concepts and systems tools for modelling signal processing in vertebrate retina

Abstract

The concept of fast and slow signals interacting by non-linear lateral processing at the inner plexiform layer and its suitable mathematical formulation, allows for a coherent interpretation of simple, complex and colour coding ganglion retinal cells of various representative vertebrates. In its simplest formulation, the processing can be expressed through non-linear spatio-temporal transformations. The formulations result in a coherent unified conceptual frame to interprete signal processing in vertebrates' retinae.
