Rostral Prefrontal Cortex (Brodmann Area 10): Metacognition in the Brain
The study of rostral prefrontal cortex (PFC) must count now as perhaps the fastest-growing new area of cognitive neuroscience. Until approximately 10 years ago, virtually nothing was known about this huge brain region (actually the largest architectonic subregion of the PFC). Now we have evidence that stretches across neuroanatomy, anthropology, brain development, cognitive neuroscience, neuropsychology, neuropsychiatry (adults and children), and, most recently, even behavioral neuroscience (Tsujimoto, Genovesio, & Wise, 2011). The purpose of this chapter is to lay out, in as straightforward a way as possible, the current state of our knowledge about this fascinating brain region. We will conclude by suggesting that perhaps the best description for the overall function of this brain region in humans would be that it is a hub formetacognition.
