A conceptual model of amphibian's tectum opticum with probabilistic coded outputs

Abstract

Systems theoretical methods used to describe lower vertebrate retinal processing [1] can be extended to include models of the amphibian tectum. Figure 1 is a diagram of the frog’s visual system with the eyes enlarged so that the ganglion cells can be illustrated collecting information from the retina and conveying it to both the optic tectum and the geniculate nucleus. Connections to the tectum are the principal ones. Experiments indicate that only the presence of blue light in the field of view is reported to the geniculate.
