The connectivity fingerprints of the frontal eye field and the inferior frontal junction
Within the prefrontal cortex, the frontal eye field (FEF) and the inferior frontal junction (IFJ) are crucial regions that mediate attention, working memory, and cognitive control functions. I comprehensively reviewed the neuroimaging evidence on these regions, suggesting that they are specialized …

Frontal cortical asymmetry and impulsive aggression.
… aggressive outbursts and measures resting frontal cortical activity. Impulsive aggression (IA) is described as a reactive or emotionally charged aggressive response characterized by a loss of behavioral control. Previous physiological studies have found IAs have sensory and informational …

Frontal collision analysis of City Car
This experiment tests the proposed crash system of the CityCar. The car is to fold during the crash to help decrease the impact force experienced by the passengers. The experiment was conducted by running a simulation of the car crashing into a wall compared to that of a rigid car with no folding, …

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, …

Cross-frontal exchange at the US Northeast shelfbreak
… economically valuable fisheries. However, cross-frontal exchange is difficult to observe directly because it is highly intermittent, non-linear, and driven by both internal frontal instability and external forcing. In this thesis, I quantify eddy-driven exchange across the US Northeast shelfbreak …

Impulsivity and frontal asymmetry in substance-dependent individuals.
Right-frontal cortical activity at rest has been associated with impulsive and aggressive behaviors. Impulsivity has also been shown to play an important role in substance dependence as an antecedent and consequence of drug use. Past research has suggested that impulsivity is a multi-dimensional …

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. …

Characteristics of Thoracic Organ Injuries in Frontal Crashes
… serious thoracic injury for belted occupants in frontal crashes. This thesis has investigated the effectiveness of airbags and the characteristics of residual thoracic organ injury incurred by belted occupants in vehicles equipped with airbags. This study was based on the injury outcome of over …

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 …

Wintertime convection and frontal interleaving in the Southern Ocean

CHARACTERIZATION OF FRONTAL CORTICAL CIRCGRIN2B_011731 IN OPIOID-INDUCED NEUROADAPATIONS
… of circGrin2b, we show that knock-down of orbitofrontal cortex (OFC) circGrin2b significantly reduces heroin intake during self-administration, while only non-significantly reducing heroin-seeking phenotypes. This suggests that OFC circGrin2b is functionally relevant to heroin self-administration …

Rapid fabrication of polymers and composites via frontal polymerization
… of minor stimuli to effect dramatic change. Frontal polymerization (FP) is an autocatalytic, propagating reaction wave driven by the exothermic polymerization of a monomer. A small thermal stimulus is applied locally to a solution of monomer and initiator, activating polymerization. The …

Evaluation of the frontal solver on the IBM PC
In this thesis, frontal subroutines are implemented to a plane frame analysis program for execution on the IBM PC. The resulting program solves for the unknown joint displacements of frame structures with large numbers of degrees of freedom by utilizing a peripheral back-up storage; which can not …
