Pattern of extrastriate visual areas connecting reciprocally with striate cortex in the mouse

Several areas reciprocally connected to striate cortex were found in the extrastriate cortex of the mouse after small single injections of horseradish peroxidase into the striate cortex. By showing that the arrangement of these labeled extrastriate areas resembles closely the physiologic and anatomic subdivision of the extrastriate cortex reported previously in several rodent species, this study supports the hypothesis that there exists a common pattern of visual cortical organization in rodents.
