Interhemispheric striate projections in the prosimian primate, Galago senegalensis.
Previous studies have shown interhemispheric visual connections in primates to be limited to extrastriate cortex. Using the retrograde transport technique of horseradish peroxidase, we show that in the prosimian primate Galago senegalensis both striate and extrastriate cortex contribute a substantial projection to the contralateral hemisphere. Thus, the lack of an interhemispheric projection from area 17 is not a characteristic of primates and may be peculiar to only a few primate species.
