要旨

We developed a physiologically plausible model of the first steps of spatial visual information processing in the fovea of the human retina. With the
predictions of this model we could support the hypothesis that, for moderate contrasts (less than or equal to 40), hyperacuity is mediated by the magnocellular
(MC-) pathway. Despite the lower sampling density in the MC pathway, as compared to the parvocellular (PC-) pathway, the information that is transferred by the
MC ganglion cells is sufficient to achieve thresholds comparable to those of human subjects in psychophysical tasks. This is a result of the much higher
signal-to-noise ratio of the MC pathway cell signals. The PC pathway cells do not transfer enough information for hyperacuity thresholds.
