The prefrontal cortex is the area of our brain associated with planning cognitively complex behaviors, and the expression of our personality. Scientists call these sophisticated tasks that happen in the prefrontal cortex “executive functions”.
Executive functions: a majority of the executive functions that we develop are via the prefrontal cortex. This allows us to help assess risk, think ahead, evaluate ourselves, set goals, and regulate our emotions.
The brain’s prefrontal cortex helps to determine the adaptive value of pleasure recorded by the nucleus accumbens and checks the urge to take the drug when it would be unwise. If the prefrontal cortex is not functioning properly, an addictive drug has more power to monopolize the reward circuit.

The prefrontal cortex and the executive control of attention we review two studies aimed at understanding the role of prefrontal cortex (pfc) in the control of attention. The first study examined which attentional functions are critically dependent on pfc by removing pfc unilaterally and transecting the forebrain commissures in two macaques.
The prefrontal cortex also known as prefrontal cortex, is a region of the brain that is located in the anterior part of the frontal lobes. Specifically, this structure is located in front of the motor and pre-motor areas of the frontal cortex, resulting in a basic region for the planning of cognitively elaborated behaviors.
Role of the prefrontal cortex and executive control in addiction. The prefrontal cortex is the part of the brain that is the cerebral cortex, which covers the front part frontal lobe. Pfc’s most typical psychological term for its functions is executive function. The prefrontal cortex has been associated with a person’s personality by more.
The primary motor cortex is the most posterior aspect of the frontal lobes (pre- central gyrus), and contains a motor “humunuclus” representing a symatotopic.

According to wikipedia, the prefrontal cortex carries out the executive functions of the brain. These include determining right from wrong, predicting future outcomes and working towards goals. Additionally, the prefrontal cortex is involved in repressing socially inappropriate behaviors.
However, the prefrontal cortex is still sensitive to experience in adulthood, and the adult brain is still able to build the complex networks required for executive.
Because the pfc is still developing during adolescence, teens don’t have the impulse control of adults. ” the implication that “impulse control” is the primary function of the prefrontal cortex is echoed in other books about the teen brain. But this explanation dramatically understates what the pfc actually does.
The role of the dorsolateral prefrontal cortex (dlpfc) in the control of behavior remains a topic of ongoing controversy. The discovery of sustained neural discharge in monkey dlpfc neurons during the retention interval of delayed-response (dr) tasks suggested that this region is involved in on-line.

We used individuals with traumatic brain injuries to examine the contribution of the dorsolateral prefrontal cortex (dlpfc)—a region important for executive.
The prefrontal cortex, located in the lower part of the frontal lobes, can be thought of as the executive center of the brain. * * it integrates information coming from the lower brain with input from the higher brain. As a result of its integrative capacities, the prefrontal cortex can regulate the survival responses from the lower brain.
The prefrontal cortex is presumed to act as a high-level gating or filtering mechanism that enhances goal-directed activations and inhibits irrelevant activations. This filtering mechanism enables executive control at various levels of processing, including selecting, maintaining, updating, and rerouting activations.
Executive functions are interrelated, and they depend on a neural circuit in which the prefrontal cortex at the front of the brain plays a prominent role.
The part of the brain that is key to reasoning, problem solving, comprehension, impulse-control, creativity and perseverance is the prefrontal cortex. These functions (called executive functions) are needed when we have to focus and think, mentally play with ideas, use our short-term working memory, and think before reacting in any situation.
Jan 1, 2008 the lateral prefrontal cortex is critically involved in broad aspects of executive behavioral control.
This situation has now changed considerably and the chapters in the prefrontal cortex—executive and cognitive functions reflect the ever-increasing degree of theoretical, and technical, sophistication that has been brought to bear on this area of study.
The prefrontal cortex is essential for executive functioning, allowing us to: organise and plan for the future; inhibit responses to distraction to achieve a goal; the dorsal and lateral prefrontal cortex regulates attention and motor responses while the ventral and medial portion regulates emotion.
Abstract: the prefrontal cortex is critical to many cognitive abilities that are considered particularly human, and forms a large part of a neural system crucial for normal socio-emotional and executive.
We review two studies aimed at understanding the role of prefrontal cortex (pfc) in the control of attention. The first study examined which attentional functions are critically dependent on pfc by removing pfc unilaterally and transecting the forebrain commissures in two macaques. The monkeys fixated a central cue and discriminated the orientation of a colored target grating presented among.
Jul 20, 2013 the prefrontal cortex, a lobe found beneath our forehead, is considered the ceo of the brain.
Thank you for this instructive, insightful article about the prefrontal cortex – the executive, the boss, and the tips for strengthening the prefrontal cortex. Your article brings together so many connections that could give us new answers.
Impulsive-aggression may result from executive dysfunction pertaining to the dorsolateral region of the prefrontal cortex, the display of premeditated aggression.
The prefrontal cortex: the different parts of the prefrontal cortex are vital to executive function. Development of the executive system the abilities of the executive system mature at different rates over time because the brain continues to mature and develop connections well into adulthood.

The prefrontal cortex is known to be a key structure for the performance of executive functions.
The prefrontal cortex (pfc) subserves cognitive control: the ability to coordinate thoughts or actions in relation with internal goals. Its functional architecture, however, remains poorly understood. Using brain imaging in humans, we showed that the lateral pfc is organized as a cascade of executive processes from premotor to anterior pfc regions that control behavior according to stimuli.
This book is devoted to the executive, emotional, social, and integrative functions of the prefrontal cortex (pfc). The pfc has usually been studied only with its executive function or with its emotional function, but recent studies indicate that the pfc plays important roles in integrating executive and emotional functions as well as in social behavior.
