Abstract
The distribution of light difference threshold throughout the visual field has been said to be mirrored rather exactly by the distribution of ganglion cells throughout the retina (e.g. Pappel and Harvey, 1973). The close correlation between psychophysical results and anatomical data has suggested the hypothesis that light difference threshold is primarily determined by retinal mechanisms. Here we present evidence that light difference threshold can also be strongly influenced by non-retinal factors. Specifically we would like to suggest that light difference threshold at a given retinal location can be modulated by interhemispheric interactions which are most likely taking place at the subcortical level. A more extensive report of these observations has been published elsewhere (Singer et al., 1977).
