The Four Streams of the Prefrontal Cortex
Description:... The prefrontal cortex contains Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47, and it is thought to be involved in psychological functions such as executive tasks, attention, and memory. This Research Topic concerns BA8, BA9, BA10, and BA11 only, since they are the most rostral and might be involved in more elementary computations as compared to, say, BA46, which is clearly involved in working memory.
This region of the brain is often treated as an undifferentiated structure, on the one hand, or as a mosaic of psychological faculties, on the other. A third option is to address the landscape of the prefrontal cortex anatomically and functionally, based on the premise that structure and function are inextricably related. This Research Topic sees itself as a descendant of Goldman-Rakic's horizontal division of the prefrontal cortex into spatial, "where", more output-oriented areas in the dorsal prefrontal cortex, and object, "what", more input-oriented areas in the ventral prefrontal cortex.
