Advances in understanding mechanisms of thalamic relays in cognition and behavior.
(J Neurosci, 2014-11-12)The main impetus for a mini-symposium on corticothalamic interrelationships was the recent number of studies highlighting the role of the thalamus in aspects of cognition beyond sensory processing. The thalamus contributes ... -
Behavioral Ecology of the Western Atlantic Short-finned Pilot Whale (Globicephala macrorhynchus)
(2015)Social structure is a key determinant of population biology and is central to the way animals exploit their environment. The risk of predation is often invoked as an important factor influencing the evolution of social structure ... -
Citizens in Fear: Political Participation and Voting Behavior in the Midst of Violence
(2014)How does violence affect political participation and voting behavior? Why does a violent context push some to be politically active, while others decide to stay at home? Our current understanding of political behavior is ... -
Corollary discharge circuits in the primate brain.
(Curr Opin Neurobiol, 2008-12)Movements are necessary to engage the world, but every movement results in sensorimotor ambiguity. Self-movements cause changes to sensory inflow as well as changes in the positions of objects relative to motor effectors ... -
Cross-modal stimulus conflict: the behavioral effects of stimulus input timing in a visual-auditory Stroop task.
(PLoS One, 2013)Cross-modal processing depends strongly on the compatibility between different sensory inputs, the relative timing of their arrival to brain processing components, and on how attention is allocated. In this behavioral study, ... -
Developmental exposure to a complex PAH mixture causes persistent behavioral effects in naive Fundulus heteroclitus (killifish) but not in a population of PAH-adapted killifish.
(Neurotoxicol Teratol, 2016-01)Acute exposures to some individual polycyclic aromatic hydrocarbons (PAHs) and complex PAH mixtures are known to cause cardiac malformations and edema in the developing fish embryo. However, the heart is not the only organ ... -
Disease Risk in Wild Primate Populations: Host and Environmental Predictors, Immune Responses and Costs of Infection
(2017)Disease risk in wild animal populations is driven by multiple factors, including host, parasite, and environmental traits, that facilitate the transmission of parasites and infection of hosts. Parasites inflict costs on ... -
Do the Clothes Make the Man? How Gaps Between Current and Ideal Self Goals Shape Product-Related Perceptions and Behavior
(2011)I present a framework that describes how perceived discrepancies from an ideal, or hoped-for, self influence how people view and behave with products associated with identity attainment (i.e., "symbolic props"). In the ... -
Does Religion Play a Part in U.S. Environmental Policymaking? The Effect of Religiously Motivated Campaign Contributions on Congressional Environmental Voting Patterns
(2012-04-27)Beginning in 1967 with Lynn White’s seminal paper, religious leaders, environmentalists, and scholars have debated whether religion plays a positive or negative role in the environmental crisis. While existing literature ... -
Estrogen’s Impact on the Specialized Transcriptome, Brain, and Vocal Learning Behavior of a Sexually Dimorphic Songbird
(2020)The song system of the zebra finch (Taeniopygia guttata) is highly sexually dimorphic, where only males develop the neural structures necessary to learn and produce learned vocalizations in adulthood. During early development, ... -
Evaluation of Environmental Behavior Change Methods at Duke University
(2011-04-29)Duke University is a leader in initiating programs geared towards campus sustainability. This project aims to conduct an evaluation of the effectiveness of several campus sustainability programs including Green Devil Challenges ... -
Feasibility and Acceptability of Door-to-Door Rapid HIV Testing Among Latino Immigrants and Their HIV Risk Factors in North Carolina
(2010)Latino immigrants in the United States are disproportionally impacted by the HIV epidemic but face barriers to clinic-based testing. We assessed a community-based strategy for rapid HIV testing by conducting "door-to-door'' ... -
Fine-Scale Foraging Behavior of Humpback Whales (Megaptera novaeangliae) in Southeast Alaska
(2017)Humpback whales (Megaptera novaeangliae) are one of the biggest animals on the planet and thus require large quantities of dense prey to meet their energetic requirements. They feed using discrete lunges and filtration to ... -
Fine-Scale Foraging Behavior of Humpback Whales Megaptera novaeangliae in the Near-Shore Waters of the Western Antarctic Peninsula
(2014)High-resolution bio-logging tools were used to examine the fine-scale foraging behaviors of humpback whales (Megaptera novaeangliae) in the coastal waters of the Western Antarctic Peninsula during the austral autumn of 2009 ... -
Paternal nicotine exposure in rats produces long-lasting neurobehavioral effects in the offspring.
(Neurotoxicology and teratology, 2019-05-16)Studies of intergenerational effects of parental chemical exposure have principally focused on maternal exposure, particularly for studies of adverse neurobehavioral consequences on the offspring. Maternal nicotine exposure ... -
Reward associations reduce behavioral interference by changing the temporal dynamics of conflict processing.
(PLoS One, 2013)Associating stimuli with the prospect of reward typically facilitates responses to those stimuli due to an enhancement of attentional and cognitive-control processes. Such reward-induced facilitation might be especially ... -
The Cognitive Mechanisms of Value-Based Choice
(2017)Nudging people towards healthier dietary choices is an important policy tool for treating and preventing obesity. However, most studies of nudging interventions fail to identify how cognitive processes change in response ... -
THE FORM AND FUNCTION OF SCALLOP MANTLE EYES
(2010)Scallops, a family of swimming bivalve mollusks, have dozens of eyes arrayed along the edges of their valves. Relatively little is known about the form and function of these unusual eyes. To learn more about them, we studied ... -
The Presence of Great White Sharks: Associations with Environmental Factors
(2011-04-28)The white shark (Carcharodon carcharias) can be regarded as one of the greatest ambush predators on Earth. White sharks have learned the best techniques, places, and times to hunt to maximize their success rate. They are ... -
The Role of Dopaminergic Systems in the Neurobehavioral Teratology of Organophosphates in Zebrafish
(2016)Background: Organophosphate (OP) pesticides are well-known developmental neurotoxicants that have been linked to abnormal cognitive and behavioral endpoints through both epidemiological studies and animal models of behavioral ...
