Emotional biases in confabulation : the role of the frontal lobes
… phenomenon have been heuristically linked to the frontal lobe impairment accompanying confabulation. The present study aims at providing direct support for this claim. A patient with damage to the prefrontal cortex is examined and his performance is contrasted with two confabulating patients, a …

Dreaming and the dorsolateral frontal lobes : towards a better understanding of the mechanism of dreaming
… findings that damage to the dorsolateral prefrontal cortex does not cause changes in these patients subjective experience of their dreams (Solms, 1997), a study was conducted in order to investigate the role of this area in dream production. The dreams of seven patients with damage to tile …

A Functional Cerebral Systems Approach to Depression: Contributions of the Left and Right Frontal Lobes
… function (and dysfunction) of the right and left frontal lobes. They go on to explain that each frontal lobe may have a direct influence on patterns of depression symptomology. In the current experiment there was an effort to look at performance differences among depressed and non-depressed males …

EEG activation patterns in the frontal lobes of stutterers and nonstutterers during working memory tasks
… more theta activity than nonstutterers in frontal regions in all conditions, both in the low theta subband (3-5 Hz) and the high theta subband (5.5-7.5 Hz). Also as hypothesized, stutterers produced more alpha activity in the low alpha subband (8-10 Hz) in frontal regions in all conditions. …

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 …

The causal role of mood in confabulation
… to remove a tumour from the diencephalon and frontal lobes, a man (CA) presented with confabulatory amnesia. Previous research papers have shown that confabulations (CA's included) have a positive emotional bias and Turnbull et al. (in press) have demonstrated that low mood appears to co-occur …

The prevalence of traumatic brain injury (TBI) and an investigation of behavioural and executive functioning outcomes (among those who have sustained TBIs) in a sample of male young offenders
… not be surprising given the vulnerability of the frontal lobes in sustaining such an injury. Considering the strong overlap between the behaviour of offenders and the behavioural outcomes of sustaining TBIs, the high prevalence rates of TBI in offending populations is not surprising (Perron & …

High-density intraoperative brain monitoring during cardiac surgery.
… of examining cere-bral oxygenation at the frontal lobes during cardiac surgery; thus, the majority of brain regions remain unmonitored. In an attempt to intraoperatively monitor broader brain regions and detect early oxygen imbalance, high-density fNIRS channels are utilized in this study. …

The Effects of Transcranial Direct Current Stimulation (tDCS) on Facial Expression Approach/Avoidance in College Students and Faculty with Broad Autism Phenotype
… study was to determine if tDCS training to the frontal lobes could increase approach toward social interactions in adults classified as BAP as demonstrated by eye-tracking measures in response to faces and gaze fixation. The study included 21 total participants recruited from the Science, …

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 …

Prediction of the Outcome in Cardiac Arrest Patients Undergoing Hypothermia Using EEG Wavelet Entropy
… (between 64-100 Hz) captured from the inferior frontal lobes are significantly more complex in the CA patients who survived (pvalue ≤ 0.02). Given that the non-invasive measurement of EEG is part of the standard clinical assessment for CA patients, the results of this study can enhance the …

Bio-social aspects of Attention Deficit Hyperactivity Disorder (ADHD): Neurophysiology, maturity, motor function and how symptoms relate to family interaction
… in children with ADHD, one involving the frontal lobes, especially on the right side, related to behavioural deviance, and another disturbance of the integration of the temporal lobes, the cerebellum and subcortical structures related to motor planning and aspects of cognition. The study …

Exploring the gene regulatory dynamics of the maturing human brain
… snRNA-seq libraries from the temporal and frontal lobes. Furthermore, Assays for Transposase Accessible Chromatin (ATAC-seq) was performed on pediatric and adult tissue and bulk ATAC-seq libraries were successfully generated. A consensus list of putative enhancers and promoters was …

Neuropsychological Effects of Hostility and Pain on Emotion Perception
… increase in high beta magnitude at the temporal lobes and a bilateral increase in delta magnitude at the frontal lobes after the cold pressor. Results suggest decreased cerebral laterality and left hemisphere activation for emotional and pain processing in high hostile men.

Multiple Memory Systems in People With Schizophrenia: Possible Effect of Atypical Anti-Psychotic Medications
… subcortical section of the forebrain, and the prefrontal cortex (PFC), located in the anterior part of the frontal lobes. Two different tests of implicit memory, the probabilistic classification learning (PCL) and the Iowa gambling task (IGT), have been shown to rely on the dorsal striatum and the …

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 Sex Differences in Cardiovascular Reactivity to Verbal and Spatial Fluency Tasks: Testing a New Model of Sex Differences in Cardiovascular Regulation and Disease
… was assessed, specifically, the role that the frontal lobes have in regulating SBP, DBP, and HR in men and women. Sex differences in the functional cerebral regulation of these cardiovascular factors were predicted. Hostility was assessed in these participants, using the Cook-Medley Hostility …

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 …
