The primate visual system is functionally and anatomically divided into two processing streams. One processes the “what” of the visual field, e.g. the color of an object. The other processes the “where” of the visual field, such as movement of an object and distance of landmarks from each other and from the self. How exactly these two streams meet, and where exactly their information is bound, is unclear. It has been hypothesized that this segregation continues all the way through the entorhinal cortex, in which the medial entorhinal cortex (MEC) computes spatial representations, while the lateral entorhinal cortex (LEC) is responsible for object representation. There is, however, evidence that (more…)
