prefrontal cortex

frontal association cortex

The anterior part of the frontal lobes of the brain, lying in front of the motor and premotor areas.nnThis brain region has been implicated in planning complex cognitive behaviors, personality expression, decision making and moderating correct social behavior. The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals.nnThe most typical psychological term for functions carried out by the pre-frontal cortex area is executive function. 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).nnMany authors have indicated an integral link between a person's personality and the functions of the prefrontal cortex. - definition adapted from Wikipedia.

Frequently Asked Questions

What is the prefrontal cortex?

The prefrontal cortex (PFC) is the anterior part of the frontal lobes of the cerebral cortex, located in front of the primary motor and premotor areas. It is the most highly developed region of the human brain and is associated with complex cognitive functions.

What functions does the prefrontal cortex serve?

The prefrontal cortex is involved in executive functions including planning, decision-making, working memory, impulse control, and goal-directed behavior. It also plays a central role in personality expression, social behavior, and the orchestration of thoughts and actions in alignment with internal goals.

How is the prefrontal cortex organized into functional subdivisions?

The PFC is commonly divided into the dorsolateral PFC (working memory, cognitive control), the ventromedial/orbitofrontal PFC (reward evaluation, emotional decision-making), and the anterior cingulate cortex (error monitoring, conflict resolution), each contributing distinct functions.

What is the clinical significance of prefrontal cortex damage?

Damage to the prefrontal cortex, as illustrated historically by Phineas Gage, results in personality changes, disinhibition, impaired judgment, and deficits in planning and impulse control. PFC dysfunction is also implicated in schizophrenia, ADHD, depression, and addiction.

How does the prefrontal cortex develop across the human lifespan?

The prefrontal cortex is one of the last brain regions to complete development, with myelination and synaptic pruning continuing into the mid-20s. This late maturation is thought to explain why adolescents show greater risk-taking and impulsivity compared to adults.
