The PFC can be divided into two broad regions, each with a different function: the lateral PFC (dorsolateral prefrontal cortex and ventrolateral prefrontal cortex) and the ventromedial PFC (also known as the orbitofrontal PFC).
How does the prefrontal cortex affect behavior?
The prefrontal cortex in primates guides behavior by selecting relevant stimuli for the task at hand, mediated through excitatory bidirectional pathways with structures associated with sensory processing, memory and emotions.
Does the frontal lobe control emotions?
The frontal lobes are considered our emotional control center and home to our personality. It's involved in motor function, problem solving, spontaneity, memory, language, initiation, judgment, impulse control, and social and sexual behavior.
What are the parts of the frontal cortex?
One way to describe the functional organization of the frontal cortex is to divide it into three areas, each having a specific brain function. These are the prefrontal cortex, the motor cortex and Broca's area. The prefrontal cortex corresponds to the superior, middle and inferior frontal gyri of the frontal lobe.

What is the prefrontal cortex?
The prefrontal cortex (PFC) relates to the portion of the brain located on the anteriormost portion of the frontal lobe, occupying portions of all three surfaces of the frontal lobe (orbital, medial and lateral surfaces). It is also called the ‘frontal granular cortex’ and ‘frontal association cortex’.
What part of the brain is the prefrontal cortex?
The prefrontal cortex comprises approximately one-third of the entire cerebral cortex . It is important to mention that this region starts to develop before birth, progresses slowly throughout childhood, and finally completes its development process (myelinization) in late adolescence. This is one of the reasons why children don't have as developed high-order cognitive abilities as adults do.
Why is the prefrontal cortex divided into three subregions?
The division of the prefrontal cortex into three different subregions is mainly due to their unique connections to other parts of the brain and their different functions.
What is the lateral prefrontal region?
The lateral prefrontal region provides the cognitive foundation for different patterns of behavior, orientation and reasoning. In addition, this region also helps in planning, the general and temporal organization of activities (e.g. daily routines), and switching from one task to another. The injuries of this region can lead to the inability to organize multiple activities in a meaningful order, to switch between the activities, and as well to adapt to rule changes. Due to its close proximity to the primary cortical center for vocalization and language production (Broca's area) this region is involved in the abstract mediation of the verbal expression of language.
Which part of the brain is responsible for decision making?
The prefrontal cortex is the region of the frontal lobe of the brain, also known as the "personality center". It is the portion of the brain that fully develops last, in late adolescence. Through its many connections to other cortical areas, the prefrontal cortex is involved in many high-order cognitive processes such as decision making, reasoning, personality expression, and social cognition.
Which artery supplies the prefrontal cortex with blood?
The prefrontal cortex receives a rich blood supply via the anterior cerebral artery and middle cerebral artery (branches of the internal carotid artery ).
Which region of the brain is responsible for impulse control?
The orbital prefrontal region is the region that participates in impulse control, emotional processing, and social cognition. Because of its rich connections with the hypothalamus, the orbital region mediates reward aspects of eating and self-regulation. Additionally, it is able to ignore distractions and help in maintaining attention on a certain task. The injuries of this region lead to the exact same symptoms that famous neurological patient Phineas Gage had (see above).
Which lobe of the brain controls the brain's functions?
The frontal lobe works alongside other brain regions to control how the brain functions overall. Memory formation, for example, depends on sensory input, which depends on numerous areas of the brain. As such, it is a mistake to attribute any one role of the brain to a single region.
What is the frontal lobe?
The frontal lobe of the brain is vital to our consciousness, as well as functions that appear uniquely human, such as spoken language. It is one of four paired lobes in the brain’s cerebral cortex, and it plays vital roles in memory, attention, motivation, and numerous other daily tasks.
How does frontal lobe damage affect personality?
Frontal lobe damage can affect personality, emotion, and behavior. Individual, couple, and family counselling may help with the management of these changes. Medications that address impulse control issues can also be useful, particularly for people who struggle with attention and motivation.
How to treat frontal lobe injury?
Treatment for frontal lobe injuries focuses on addressing the cause of the injury first. A doctor might prescribe medication to treat an infection, surgery to remove a growth, or medication to reduce the risk of a stroke.
What is the struggle of frontal lobe damage?
People with frontal lobe damage often struggle with gathering information, remembering previous experiences, and making decisions based on this input.
Which lobe is located near the forehead?
The frontal lobe is located near the forehead and plays a vital role in motivation and memory.
How does the brain learn to work?
The brain can sometimes learn to work around an injury as other regions compensate for damage to the frontal lobe. Occupational, speech, and physical therapy can move this process along. These treatments can prove especially helpful in the early stages of recovery, as the brain begins to heal.

Does LSD affect serotonin?
in addition to the neurotransmitter serotonin in the brain , LSD can also affect
What is the cerebral cortex?
Your cerebral cortex is the outermost layer of your brain. Its surface has many folds, giving it a wrinkled appearance. The folds consist of many deep grooves called sulci and raised areas called gyri. These folds add to the surface area of your cerebral cortex, allowing large amounts of information to be processed by more nerve cells.
Why is the cerebral cortex called gray matter?
The gray matter found in the outer layer of your brain consists of nerve cell bodies, including the end portion of nerves called dendrites. Dendrites are the part of a nerve cell that receives the chemical message from another cell. Your cerebral cortex is gray because that section of the nerve lacks the fatty covering material called myelin.
What is the neocortex?
Most of your cerebral cortex is considered to be the neocortex. “Neo” means new. Your neocortex is so named because its appearance is thought to be relatively new in vertebrate evolution. In humans, 90% of the cerebral cortex is the neocortex.

Some researchers look at the brain in another way and classify the areas of the cerebral cortex by their three main types of functions: sensory, motor and association areas.
How might the cerebral cortex be damaged?
Damage to any area of your cerebral cortex typically results from tumors, trauma, autoimmune diseases or a cerebrovascular accident (brain bleed or stroke).
What is the basic activity of the prefrontal cortex?
The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals. Many authors have indicated an integral link between a person's will to live, personality, and the functions of the prefrontal cortex.
What is the prefrontal cortex?
In mammalian brain anatomy, the prefrontal cortex ( PFC) is the cerebral cortex which covers the front part of the frontal lobe. The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47. The basic activity of this brain region is considered to be orchestration ...
What is the electrically silent area of the frontal cortex?
Electrically silent area of frontal cortex. A third definition of the prefrontal cortex is the area of frontal cortex whose electrical stimulation does not lead to observable movements. For example, in 1890 David Ferrier used the term in this sense.
What is the ventrolateral prefrontal cortex?
The ventrolateral prefrontal cortex (VLPFC) has been implicated in various aspects of speech production and language comprehension. The VLPFC is richly connected to various regions of the brain including the lateral and medial temporal lobe, the superior temporal cortex, the infertemporal cortex, the perirhinal cortex, and the parahippoccampal cortex. These brain areas are implicated in memory retrieval and consolidation, language processing, and association of emotions. These connections allow the VLPFC to mediate explicit and implicit memory retrieval and integrate it with language stimulus to help plan coherent speech. In other words, choosing the correct words and staying “on topic” during conversation come from the VLPFC.
How many ways are there to define the prefrontal cortex?
There are three possible ways to define the prefrontal cortex:
Which prefrontal cortex contains the frontal eye fields?
The dorsolateral prefrontal cortex contains BA8, including the frontal eye fields. The ventrolateral prefrontal cortex contains BA45 which is part of Broca's area. Some researchers also include BA44 the other part of Broca's area.
Which two scientists identified the prefrontal cortex as the projection zone of the mediodorsal nucleus of?
To define the prefrontal cortex as the projection zone of the mediodorsal nucleus of the thalamus builds on the work of Rose and Woolsey, who showed that this nucleus projects to anterior and ventral parts of the brain in nonprimates, however, Rose and Woolsey termed this projection zone "orbitofrontal." It seems to have been Akert, who, for the first time in 1964, explicitly suggested that this criterion could be used to define homologues of the prefrontal cortex in primates and nonprimates. This allowed the establishment of homologies despite the lack of a granular frontal cortex in nonprimates.
Anatomy
- The prefrontal cortex (PFC) is connected to many other parts of the brain and is able to send and receive information. The prefrontal cortex is divided into these two parts:1 1. Medial PFC (mPFC): It is involved in self-reflection, memory, and emotional processing. 2. Lateral PFC (lPFC): It is inv…
Associated Conditions
- Damage to the prefrontal cortex can happen from: 1. Brain trauma: Accidents, falls, sports injuries, and physical altercations can cause a traumatic brain injury. 2. Cancer: Cancer originating in the brain (primary tumors) or spreading to the brain from other original sites (metastatic brain tumors) can cause damage. 3. Tumors: In addition to cancerous tumors, benign (noncancerous…
Tests
- If you have damage to the prefrontal cortex or another condition that is affecting it, your healthcare provider may start with a physical exam and a mental status exam. These tests will help them evaluate your thinking and rule out other conditions. To check your brain, a healthcare provider may order the following tests: 1. Magnetic resonance imaging (MRI): Detailed images t…
Summary
- The prefrontal cortex is found in front of the frontal lobe of the brain. It affects your behavior, personality, and executive function. When the prefrontal cortex is damaged, it can cause changes to how you think and behave.
A Word from Verywell
- It is important to remember that you may not always notice changes in your behavior or thinking. Your friends and loved ones are more likely to point out that something is wrong. Even if you think everything is fine, it is worth having a conversation with your healthcare provider and checking on your brain health. It is better to catch problems earlier and get treatment.
