frontal lobe functioning and its relationship to cognition emotion

Impairments in these frontal lobe functions could, in turn, have a negative The relationship between off-task cognition (?mind wandering?), fluctuations of. The ability of the right frontal lobe may be unique in integrating cognitive and affective Finally, psychological tests which assessed cognitive functions that might be .. The connectivity with brain regions related to affect and feelings has been. In phylogeny as in ontogeny, the association cortex of the frontal lobe, also known as the of cognitive functions that neuropsychological studies in animals and involved in the expression and control of emotional and instinctual behaviors.

MRI studies have shown that the frontal area is the most common region of injury following mild to moderate traumatic brain injury Levin et al. There are important asymmetrical differences in the frontal lobes.

Cognitive and emotional components of frontal lobe functioning in childhood and adolescence

The left frontal lobe is involved in controlling language related movement, whereas the right frontal lobe plays a role in non-verbal abilities. Some researchers emphasize that this rule is not absolute and that with many people, both lobes are involved in nearly all behavior.

Disturbance of motor function is typically characterized by loss of fine movements and strength of the arms, hands and fingers Kuypers, Complex chains of motor movement also seem to be controlled by the frontal lobes Leonard et al. Broca's Aphasia, or difficulty in speaking, has been associated with frontal damage by Brown An interesting phenomenon of frontal lobe damage is the insignificant effect it can have on traditional IQ testing.

Researchers believe that this may have to do with IQ tests typically assessing convergent rather than divergent thinking. Frontal lobe damage seems to have an impact on divergent thinking, or flexibility and problem solving ability. There is also evidence showing lingering interference with attention and memory even after good recovery from a TBI Stuss et al.

Another area often associated with frontal damage is that of "behavioral sponteneity. One of the most common characteristics of frontal lobe damage is difficulty in interpreting feedback from the environment.

Perseverating on a response Milner,risk taking, and non-compliance with rules Miller,and impaired associated learning using external cues to help guide behavior Drewe, are a few examples of this type of deficit.

The frontal lobes are also thought to play a part in our spatial orientation, including our body's orientation in space Semmes et al. One of the most common effects of frontal damage can be a dramatic change in social behavior. A person's personality can undergo significant changes after an injury to the frontal lobes, especially when both lobes are involved.

There are some differences in the left versus right frontal lobes in this area. Left frontal damage usually manifests as pseudodepression and right frontal damage as pseudopsychopathic Blumer and Benson, Sexual behavior can also be effected by frontal lesions.

What Does the Brain's Frontal Cortex Do? (Professor Robert Sapolsky Explains)

Orbital frontal damage can introduce abnormal sexual behavior, while dorolateral lesions may reduce sexual interest Walker and Blummer, Some common tests for frontal lobe function are: The proposed studies will investigate the cognitive and neural mechanisms of three cognitive domains that are difficult for Veterans with PTSD: The project will use a direct measure of the brain's electrical activity to determine when in the information processing stream potential weaknesses occur.

The project will also record electroencephalographic EEG activity at rest to examine possible changes in connectivity associated with PTSD.

The relationship between off-task cognition? The proposed studies will contribute to larger efforts to characterize this Veteran population by including PhenX common data elements and easily replicated methods that can be implemented at other research sites. An innovative aspect of the current proposal is its novel approach to resting state EEG, which is easier and less expensive to collect than resting state fMRI. The observed patterns of EEG network activity will be related to specific?

We hope the project will lead to broader efforts to characterize the brain states correlated with maladaptive thoughts in a naturalistic setting, with possible use of this knowledge in the future to predict clinical response to treatment.

Public Health Relevance New approaches are needed to identify and characterize the nature of the cognitive weaknesses seen in Veterans with post-traumatic stress disorder PTSD. Impairments in specific executive control functions could hinder the effectiveness of prolonged exposure and cognitive processing therapy, the most strongly recommended psychotherapies for Veterans.

Therefore, studies assessing the cognitive and neurophysiological factors associated with chronic PTSD are critical.
