"A tale of two visual systems"

In 1969, Gerald Schneider's Science paper outlined evidence for two visual systems in rodents; one based on the outputs of the superior colliculus and the other on the outputs of primary visual cortex (V1). More recently, there has been much support for the concept of two visual cortical streams in primates, a dorsal one for motor behavior, and a ventral one for object identification, with both emanating from V1. Now, investigators are describing "dorsal" and "ventral" processing streams from V1 in mice. I will show how the two visual systems of Schneider relate to the dorsal and ventral streams of primates, and that the "dorsal" and "ventral" streams of rodents do not.
