Motor Network Organization in Frontal Lobe Epilepsy
Frontal lobe epilepsy (FLE) is a seizure disorder that commonly coincides with functional motor deficits. While the source of these deficits is unknown, it is postulated that repeated seizure activity within the frontal lobe might impact the proximate motor network. To examine this hypothesis, …

Metamemory and frontal lobe function in the elderly.
… to examine the relation between metamemory and frontal lobe function in the elderly. Three age groups were included in the study to address these issues: a Young Control group (18-30 yrs); a Young-Old group (60-75 yrs); and an Old-Old group (76-90 yrs). Metamemory was assessed in two ways. …

Frontal-lobe mediated word retrieval in Parkinson's disease
… executive functioning, which is mediated by the frontal lobes of the brain. Tests of verbal fluency have been used to evaluate frontal lobe dysfunction. Letter fluency, however, may require different processes and mechanisms than semantic fluency. Martin and colleagues (1994) found that letter …

Cognition and depression in cerebellar and frontal lobe stroke patients
… compare the cognitive profile of patients with frontal lobe (N = 28) versus cerebellar (N = 31) strokes, 2) examine the effects of depression on cognition, and 3) to understand how structural and emotional factors relate to cognitive functioning. Results are consistent with previous findings of …

Frontal lobe asymmetry and impulsive aggression : a reinforcement sensitivity study.
… individuals and nonaggressive controls using frontal cortical EEG activity. Impulsive aggression is a reactive or emotionally charged violent response characterized by a loss of behavioral control. Previous physiological studies have found impulsive aggressors (IAs) have sensory and …

Predicting Future Age-Related Cognitive Delcine: Processing Speed and Frontal Lobe Functioning
… Mini-Mental State Examination), and prefrontal mediated neuropsychological tests (Trail Making A and B; verbal and category fluency; WAIS digits forward and backwards, California Verbal Learning Test proactive interference index). Regression analyses assessed which theoretical approach, …

Frontal Lobe Correlates in Hostile Men: Analysis of Facial Motor Tone and Cardiovascular Regulation
… the proposed relationship between right orbitofrontal functioning and hostility.

Investigation into the frontal lobe functioning of young offenders with and without a head injury
… with tasks that involve executive and frontal lobe functioning compared to non-offenders, but research has often not recorded or controlled for the effect of head injury. This research aimed to investigate whether young offenders in the community, with self-reported traumatic brain …

The Effect of Frontal Lobe Stress on Gambling Task Performance: Implications for Understanding Addictive Behavior
… resulting from impaired functioning of the frontal lobes. Previous research suggests that two important cognitive processes regarding decision making are reversal learning (e.g. Fellows and Farah, 2005) and working memory (e.g. Hinson, Jameson, and Whitney, 2002; Jameson, Hinson, and …

A neuropsychological investigation of verbal and nonverbal fluency: perspectives on asymmetries in frontal lobe functioning
… with verbal impairments associated with left frontal pathology and nonverbal impairments with right frontal involvement. These fluency constructs, however, have not been systematically examined in conjunction with one another, or with other frontally-mediated tasks. Therefore, this experiment …

Differential Efficts of Hostility on Frontal Lobe Performance: A dual task approach with Fluency and Cardiovascular Regulation
… regulation and nonverbal fluency are both right-frontal tasks, it was predicted that high hostile men would evidence increased interference on cardiovascular regulation concurrent with the nonverbal fluency task in comparison with low hostile men. It was also predicted that high-hostile males …

Resting-state and task functional magnetic resonance imaging correlates of early language development in temporal and frontal lobe
… on two nodes. Those two nodes are the inferior frontal gyrus (IFG), which is implicated in syntactic processing, and middle temporal gyrus (MTG), which is implicated in semantic processing, with the goal of understanding how the language network emerges. I use two groups of participants and …

Challenging frontal lobe capacity using lateralized vestibular stress: A functional cerebral systems approach to a clinical risk for falls
… cerebral systems framework. The claim was that frontal regions exert regulatory control over posterior systems for sensation and autonomic functions in a dense, interconnected network with right hemisphere specialization. As a preponderance of evidence demonstrates that a design fluency task is …

An Assessment of Frontal Lobe Activity and BDNF Levels Following Concussion in Collegiate Athletes: A Near-Infrared Spectroscopy Study
… spectroscopy (NIRS) was used to measure prefrontal cortex (PFC) activity during the dot-probe task of affective attentional bias. Brain-derived neurotrophic factor (BDNF) levels are related to frontal lobe activity, recovery from brain injury, attention, and affective processing. Therefore, …

Performance of Adults With and Without Attention-Deficit/Hyperactivity Disorder (ADHD) on Measures of Response Inhibition and Frontal Lobe Functioning
In this study 2 groups of adults, those with and without ADHD, were studied in terms of cognitive functioning and symptoms of ADHD, depression, anxiety, and substance abuse. Due to the difficulties in diagnosing ADHD in this population three methods of diagnosis were used and the resulting findings …

Frontal lobe dysfunction, as measured by the frontal systems behavioural scale, in the context of HIV infection and heavy episodic drinking
Background: The frontal lobe of the human brain is integral in regulating behaviour. Behavioural disturbances such as apathy, disinhibition, and dysexecutive function are well-known consequences of frontal lobe pathology, leading to significant impairment. Heavy episodic drinking (HED) and HIV are …

A Functional Cerebral Systems Approach to Hostility: Changes in Frontal Lobe Delta Activation and Fluency Performance as a Function of Stress
… have historically been associated with the frontal lobes. Moreover, research has demonstrated the importance of cerebral laterality with a prominent role of the right frontal regions in the regulation of negative affect (anger, hostility) and in the generation or fluent production of designs …

Verification of the narratives test with perseveration responses on the Wisconsin Card Sorting and category tests
