Wiener kernels determination in the cats lateral geniculate nucleus as a function of velocity of a sinusoidal...

The aim of this work was to develop a mathematical model which could describe information collected in the lateral geniculate body in response to the movement of a specific stimulus in an animal's visual field. To do this, a visual stimulation technique was developed, as well as a group of computer programs for processing the information recorded during the experiments. This group of programs is a method of non-linear identification based on the Wiener Kernels method, with the speed of an image's motion in the visual field as the systems entry variable. Preliminary results have shown that non-linearities in visual information processing would also be involved in speed coding. Thus a further utilization of the Wiener method seems useful and could contribute a great deal to visual system analysis.
