The studies reviewed support an association between frontal lobe dysfunction and increased aggressive and antisocial behaviour. Focal orbitofrontal injury is specifically associated with increased aggression.
Does damage to the frontal lobe affect behavior?
As a whole, the frontal lobe is responsible for higher cognitive functions such as memory, emotions, impulse control, problem solving, social interaction, and motor function. Damage to the neurons or tissue of the frontal lobe can lead to personality changes, difficulty concentrating or planning, and impulsivity.
Which brain lobe is responsible for aggression?
Two brain areas involved in the neural network of aggressive behavior are the amygdala and the hypothalamus.
How does the frontal lobe affect anger?
It is notable that frontal regions implicated in the regulation of emotion, orbital, medial and ventrolateral frontal cortex, have also been implicated in the anger response. Thus, anger induction studies have found this emotion associated with increased activity in these regions [8, 9].
What is the role of the frontal cortex in aggression?
Knowledge stored in the human prefrontal cortex may exert control over more primitive behavioral reactions to environmental provocation. Therefore, following frontal lobe lesions, patients are more likely to use physical intimidation or verbal threats in potential or actual confrontational situations.
Is aggression inherited or learned?
Aggression in childhood: Rooted in genetics, influenced by the environment. Summary: According to a new psychosocial study, reactive and proactive types of aggressive behavior in 6-year-old children share most of the same genetic factors.
What part of the brain controls fear and aggression?
Amygdala. The amygdala helps coordinate responses to things in your environment, especially those that trigger an emotional response. This structure plays an important role in fear and anger.
Which side of the brain controls anger?
The neural system for emotions linked to approaching and engaging with the world – like happiness, pride and anger – lives in the left side of the brain, while emotions associated with avoidance – like disgust and fear – are housed in the right. But those studies were done almost exclusively on right-handed people.
Can concussion cause frontal lobe damage?
A concussion can affect the frontal lobe by impairing judgment, impacting attention span and organization. Dysregulation to the frontal lobe caused by concussions or other brain injuries can result in loss of motivation and irrational or impulsive behavior.
What is traumatic brain syndrome?
Traumatic Brain Injury (TBI) is a disruption in the normal function of the brain that can be caused by a blow, bump or jolt to the head, the head suddenly and violently hitting an object or when an object pierces the skull and enters brain tissue.
What is Brunner syndrome?
Brunner syndrome is a recessive X-linked disorder characterized by impulsive aggressiveness and mild mental retardation associated with MAOA deficiency (Brunner et al., 1993).
Are you born with aggression?
There is no gene or system in the body that can be identified as “for aggression.” While it appears clear that genetic variation in neurotransmitters and hormones can be involved in the ways in which we express aggressive behavior, there is no direct or casual link. Our genes cannot make us aggressive.
Which side of the brain controls memory?
right Our brains have two sides, or hemispheres. In most people, language skills are in the left side of the brain. The right side controls attention, memory, reasoning, and problem solving. RHD may lead to problems with these important thinking skills.
