Effects of PCBs and PBDEs on response inhibition and dopaminergic signaling
… PCB exposure has been associated with impulsive behavior in laboratory species and human cohorts, while little is known about whether PBDEs have similar effects. Both PCBs and PBDEs have been shown to perturb dopaminergic neurotransmission. The behavioral and neurochemical effects of …

Elucidation of pharmacologically manipulated responding in the delay discounting task in high alcohol preferring mice
<p>Impulsive behavior is the hallmark of many psychopathologies. Uncovering the neurobiological mechanisms driving impulsivity is paramount in the development of through the delay discounting (DD) task in both human and animal models. The present study is an examination of the predictive validity …

Discounting of Delayed and Probabilistic Rewards by Women with and without Binge Eating Disorder
… outcomes, may provide an objective assessment of impulsive behavior. Impulsivity may perpetuate binge eating, but discounting tasks have never been evaluated with eating disordered individuals. A discounting procedure could help differentiate individuals with eating/weight problems from controls …

Univariate and Multivariate fMRI Investigations of Delay Discounting and Episodic Future Thinking in Alcohol Use Disorder
… rehabilitation strategies. The propensity for impulsive decision making (choosing smaller, sooner rewards over larger, later ones) also known as delay discounting (DD), is an established risk-factor for a variety of substance abuse disorders, including AUD. Brain mapping of DD routinely uses …

Three empirical analyses of behavioral and nutrition policy influences on dietary choices
… risk of some of these conditions or disorders, behavioral factors play a significant role in the demand for food products. In the first essay, I find that external stimuli do increase calorie intake, and that restraint behavior does not fully compensate for the excess calories. Another important …

Time-domain Modeling of Light Matter Interactions in Active Plasmonic Metamaterials
… due to the nature of transient, nonlinear, and impulsive behavior, the time domain modeling approach is viewed as the most viable method. In this work, we develop a time-domain model (method of finite-difference time-domain (FDTD)) of light matter interactions in active plasmonic metamaterials. …

Performance of Ds/ssma Communications in Impulsive Channels (Nongaussian, Hard Limiter)
… additive channel noise, which is attributed to impulsive noise sources in the environment. The contribution of multiple-access interference is examined by considering K users transmitting simultaneously over a linear channel using the binary PSK direct-sequence SSMA technique. Alternatively, the …
