What is an orbitofrontal bark?
Orbitofrontal bark is the smallest part of the frontal lobe in the brain. This area of the prefrontal cortex is found in the cranial cavity directly behind the eyes and is involved in a large part of the decision -making process. Part of this brain structure plays a role in creating pleasant or discomfort caused by many flavors and scents. During tests that measure brain activity, it is considered to be highly active in all tasks that include learning new information. The media part or in the middle of this brain structure helps the brain to process an aspect of remuneration. The lateral or side part helps the brain to process the value of actions. The interaction between the reward processors and the punishment in the orbitofrontal bark is an important factor in the ability of a person to learn from mistakes and change destructive bevzory.
Within the orbitofrontal cortex, the emotions and the process of thinking combine and affect the daily decision that the person accepts. Damage caused by injury or lesion growth in it can cause changes to axis behaviorOBY. Behavior patterns may change because of the significant impact that the peel has to appreciate events, objects or people. Orbitofrontal cortex is also involved in many brain processes that exist in the minds of people with addiction, including the desire for an unhealthy substance or activity.
historically treatment of personality and psychosis disorders included surgical excision of parts of orbitofrontal bark. The procedure, called the frontal lobotomy, was used when other treatment methods failed. People who underwent frontal lobotomy often reported a sense of emotionally flat after a feather least post-surgical absence of disturbing behavior patterns and decreased psychosis symptoms often validated invasive brain surgery.
Another part of the orbitofrontal bark plays a role in the formation of food preferences. The taste of food can cause a pleasant reaction or discomfort that comes from the bark. Even sensory information related toThe texture of food is passed through it. Deciding whether to re -consume the same meal is an example of integrating sensory information into the process of thinking by this brain structure.
Test used by scientists to measure activity in orbitofrontal bark is called scanning of functional display of magnetic resonance imaging (FMRI). It measures changes in blood flow in the brain in different types of activities. During the period of increased stimulation images FMRI show that blood flow is amplified in the prefrontal cortex.
