p087fig03.01 A macrocircuit of key visual processes (in green) and the cortical areas in which they primarily occur (in red), from the retina to the Prefrontal Cortex (PFC), including both the What and Where cortical streams.  The [bottom-up, horizontal, and top-down] interactions help each of these processes to overcome computationally complementary processing deficiencies that they would experience without them, and aso to read-out top-down expectations that help to stabilize learning while they focus attention on salient objects and positions.<BR>||  Emerging unified theory of visual intelligence. [What, Where] streams.  Bottom-up and top-down interactions overcome COMPLEMENTARY processing deficiencies.
