Structure-Function and Behavioral Studies on the Glutamate Delta-1 Receptor
… a first step we conducted electrophysiological studies on the rat clone of GluD1 to study the activation gate and ligand binding domain of GluD1 receptor. Site directed mutagenesis in the SYTANLAAF region resulted in four constitutively open mutants GluD1A650C, GluD1L652A, GluD1A654C, and …

Genetic, biochemical and behavioral studies of the chemotactic response in Bacillus subtilis
The two enzymes involved in the major adaptation pathway of Bacillus subtilis chemotaxis were cloned and sequenced. They were found to be homologous to the corresponding enzymes of the Escherichia coli system. While the B. subtilis proteins could substitute for the E. coli proteins, they play …

Into the Wild: Deploying Brain and Physiological Sensing in Natural Environments to Enhance Wake and Sleep Cognitive Behavioral Studies
… experimental platforms for performing cognitive behavioral studies in natural settings: one for wake time and one for sleep. The equipment utilized today in behavioral and sleep labs is not very accessible, comfortable, portable, or simple to operate. The systems documented in this dissertation …

The Role of Context in Understanding and Predicting Pedestrian Behavior in Urban Traffic Scenes
… we conduct a meta-analysis of a large body of behavioral literature and identify the factors that potentially impact pedestrian behavior and how these factors are interconnected. We extend the past findings by conducting two behavioral studies of pedestrians. The first study shows that …

Molecular, cellular, and circuit analysis of C. elegans spitting behavior
… goal in neurobiology. One simple system for such behavioral studies is the pharynx of the nematode worm C. elegans, which contracts rhythmically (pumps) to ingest food. The connectivity (connectome) of the 20 pharyngeal neurons has been completely determined, making the pharynx one of the …

Incremental lexical learning in speech production: a computational model and empirical evaluation
… of a picture of a cat (semantic interference). Behavioral studies suggest that these effects derive from persistent changes in the way that words are activated and selected for production, and some have claimed that the findings are only understandable by positing a competitive mechanism for …

An exploration of the effects of data aggregation and other factors on empirical estimates of market power
Econometric studies of firm-level behavior are gaining acceptance among some industrial organization economists. This is a potentially useful tool for detecting noncompetitive behavior. Policy makers and antitrust enforcement officials are interested in the results of these studies as they are …

Comparative efficacies of decision strategies and the effects of learning in dynamic environments: a computer simulation approach
… result of using heuristics that are derived from behavioral studies which focused on discrete incidents. This approach fails to recognize decision making as a continuous process and overlooks the importance of feedback. This study examines the performance of various decision strategies …

Aggressive behavior in adolescents with fetal alcohol spectrum disorders
Behavioral studies of fetal alcohol spectrum disorders (FASD) have indicated that aggression is common amongst alcohol-exposed adolescents, and that it appears to become more prevalent with age in that population. Such studies have documented the presence of aggression as a behavioral outcome, but …

The perception of risk : a summary of studies and how they pertain to the future of nuclear energy
… and specifically to nuclear power by reviewing behavioral studies examining how risk is perceived. The paper also discusses important themes relevant to nuclear power and risk perception, including trust, stigma, the difference between experts and the public, and ways of informing and educating …

Exploration of the influence of emotionally primed environments on creativity and related patterns of brain activity
… to concept generation in early phases. Two behavioral studies were conducted to investigate whether environments with emotional stimuli would influence creativity, and in particular divergent thinking capacity. The stimuli independently considered were music and pictures. These stimuli sets …

Short-Term Visual Deprivation, Tactile Acuity, and Haptic Solid Shape Discrimination
… to visual deprivation (Boroojerdi et al., 2000). Behavioral studies have recently documented enhanced tactile abilities following a short period of visual deprivation (Facchini & Aglioti, 2003; Weisser, Stilla, Peltier, Hu, & Sathian, 2005). The current study investigated the effects of visual …

The Development and Use of a Color Discrimination T-Maze Learning Task in the Zebrafish (<i>Danio rerio</i>)
… rerio) are becoming increasingly utilized in behavioral studies as a model of human learning and memory. The results of a previous study by Colwill, Raymond, Ferreira, and Escudero (2005) indicated that this species is capable of discriminating between colors and learning to respond to an …

Role of Hepatic Lipoprotein Receptor-related Protein 1 (LRP-1) on Amyloid Beta Pathology in a Mouse Model of Amyloidosis
… LRP1 group (n=7). 12 weeks after LRP1 silencing, behavioral studies including Y-maze, nesting behavior, and open-field testing, were performed, and mice were sacrificed. The brain, liver, and plasma were collected to measure Aβ load using immunoassays. After performing all these studies, we did …

Youths as behavior change agents in an institution
<p>Behavioral studies have shown that youths in various settings can function effectively as behavior change agents. This study used five 15 to 18 year old male youths in a closed institutional setting as behavior change agents for five male Youth Counselors. Youths specified staff behaviors they …

Learning to Forget: An Interference Account of Cue-Independent Forgetting
… can explain cue-independent forgetting. Three behavioral studies tested predictions of the neo-classic interference theory. Experiment 1 found support for recovery interference in testing key predictions of the theory within the think/no-think paradigm. Most importantly, learning to quickly …
