ABSTRACT
A great deal of what is known about the integrative parts of the back cortex comes from the visual system, so the authors will build on that information. Signals from the visual cortex travel to the integrative regions in the back cortex via two different routes. It turns out that the upper and lower areas of the back integrative cortex are responsible for very different things. The upper route leads to understanding where things are. It analyzes spatial relationships and pays particular attention to how things are arranged especially when the authors want to copy that arrangement (i.e., mimic something). Knowing what is an important step in beginning to comprehend our experience, but knowing where may be even more important. Knowing where things are gives us relationships. Spatial relationships tell us the detailed structure of the material world, and this structure leads to function.
