Anatomical terms of neuroanatomy |
In mammalian brain anatomy, the prefrontal cortex (PFC) covers the front part of the frontal lobe of the cerebral cortex. It is the association cortex in the frontal lobe.[2][3] The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47.[1]
This brain region is involved in a wide range of higher-order cognitive functions, including speech formation (Broca's area), gaze (frontal eye fields), working memory (dorsolateral prefrontal cortex), and risk processing (e.g. ventromedial prefrontal cortex). The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals.[4] Many authors have indicated an integral link between a person's will to live, personality, and the functions of the prefrontal cortex.[5]
This brain region has been implicated in executive functions, such as planning, decision making, working memory, personality expression, moderating social behavior and controlling certain aspects of speech and language.[6][7][8][9] Executive function relates to abilities to differentiate among conflicting thoughts, determine good and bad, better and best, same and different, future consequences of current activities, working toward a defined goal, prediction of outcomes, expectation based on actions, and social "control" (the ability to suppress urges that, if not suppressed, could lead to socially unacceptable outcomes).
The frontal cortex supports concrete rule learning, with more anterior regions supporting rule learning at higher levels of abstraction.[10]
The prefrontal cortex is the anterior section of the brain's frontal lobes. Central to the top-down control of attention, inhibition, emotion, complex learning, and theory-of-mind processing, the prefrontal cortex is a heterogeneous brain circuit composed of many important subdivisions (Duncan, 2001).
