Radiation Effects On Dopamine-Mediated Prepulse Inhibition In The C57bl/6 Mouse, Cara Nicole Zuccarelli Miller

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the effects of proton and gamma radiation on a dopamine-dependent sensory gating mechanism: prepulse inhibition of the startle reflex. The purpose of this research was to describe potential hazards of proton radiation to the central nervous system in long-term space fight and for proton therapy patients. Results from previous research indicate that startle behavior is modified by proton and iron radiation. Forty-eight 10-½ week old, male C57BL/6 mice were used to characterize the optimal parameters for the model (prepulse duration, probe duration, and stimulus-onset-asynchrony). Three hundred and fifty two mice were used to characterize the time course …

A Research Agenda For Political Personality And Leadership Studies: An Evolutionary Proposal, Aubrey Immelman, Theodore Millon

Psychology Faculty Publications

Despite major neuroscientific advances in the past two decades and parallel conceptual refinement in evolutionary theory, personality-in-politics inquiry remains adrift, divorced from these broader spheres of scientific knowledge. This paper reviews the neurobiological substrates of three major domains of evolutionary biology and behavioral ecology relevant to political personality assessment and the psychological examination of political leaders; furnishes a context and set of guiding ideas to revitalize the study of the person as biopsychosocial entity in politics; advances a generative theory of personality and political leadership performance; and proposes an agenda for advancing personality-in-politics and leadership inquiry, informed by insights derived …

Gamma Oscillations Correlate With Working Memory Load In Humans, Marc W. Howard, Daniel S. Rizzuto, Jeremy B. Caplan, Joseph R. Madsen, John Lisman

Psychology - All Scholarship

Functional imaging of human cortex implicates a diverse network of brain regions supporting working memory—the capacity to hold and manipulate information for short periods of time. Although we are beginning to map out the brain networks supporting working memory, little is known about its physiological basis. We analyzed intracranial recordings from two epileptic patients as they performed a working memory task. Spectral analyses revealed that, in both patients, gamma (30-60 Hz) oscillations increased approximately linearly with memory load, tracking closely with memory load over the course of the trial. This constitutes the first evidence that gamma oscillations, widely implicated in …

Trends. Terrorist Brains, Ibpp Editor

International Bulletin of Political Psychology

This Trends article discusses the construct of biological reductionism in the context of the case of Red Army Faction member Ulrike Meinhof. For the author, overly emphasizing the biological aspects of Ms. Meinhof’s case might obscure legitimate grievances, and ultimately, lead to more cases of violence associated with terrorism.

A Twins Study Of Communicative Adaptability: Heritability Of Individual Differences, Michael J. Beatty, Lenora A. Marshall, Jill E. Rudd

Communication Faculty Publications

Recently, a model of communication theory and research has appeared in the literature within which stable individual differences in communication behavior represent individual differences in activation thresholds of neurobiological systems. The neurobiological systems thought to underly communication traits and behavior are assumed to be primarily due to genetic inheritance. As such, the model assigns a limited role to adaptability in social situations, instead positing communication adaptability as an inherited trait. In the present study, heritability estimates for the dimensions of communicative adaptability were derived from correlations based on identical and fraternal twins' responses to a multidimensional communicative adaptability measure. Results …

Evolutionary Analysis In Law: Some Objections Considered, Owen D. Jones

Vanderbilt Law School Faculty Publications

This Article appears in a special issue of the Brooklyn Law Review on DNA: Lessons from the Past - Problems for the Future. It first addresses why law needs insights from behavioral biology, and then identifies and responds to a variety of structural and conceptual barriers to such evolutionary analysis in law.

Law And The Biology Of Rape: Reflections On Transitions, Owen D. Jones

Vanderbilt Law School Faculty Publications

This Article serves is a sequel to a previous Article: Sex, Culture, and the Biology of Rape: Toward Explanation and Prevention, 87 Cal. L. Rev. 827 (1999). Part I briefly considers the threshold question: why consider the behavioral biology of sexual aggression at all? Part II proposes that the first step in transitioning to a more accurate and more useful model of rape behavior is to avoid a number of common definitional ambiguities that plague most rape discussions. Because those ambiguities are particularly likely to foster misunderstandings about biobehavioral perspectives, Part II also clarifies the scope of what biobehavioral theories …

Age Differences In Behavior And Pet Activation Reveal Differences In Interference Resolution In Verbal Working Memory, Alan Hartley, John Jonides, Christina Marshuetz, Edward E. Smith, Patricia A. Reuter-Lorenz, Robert A. Koeppe

Scripps Faculty Publications and Research

Older adults were tested on a verbal working memory task that used the item-recognition paradigm. On some trials of this task, response-conflict was created by presenting test-items that were familiar but were not members of a current set of items stored in memory. These items required a negative response, but their familiarity biased subjects toward a positive response. Younger subjects show an interference effect on such trials, and this interference is accompanied by activation of a region of left lateral prefrontal cortex. However, there has been no evidence that the activation in this region is causally related to the interference …

Age Differences In The Frontal Lateralization Of Verbal And Spatial Working Memory Revealed By Pet, Alan Hartley, Patricia A. Reuter-Lorenz, John Jonides, Edward E. Smith, Andrea Miller, Christina Marshuetz, Robert A. Koeppe

Scripps Faculty Publications and Research

Age-related decline in working memory figures prominently in theories of cognitive aging. However, the effects of aging on the neural substrate of working memory are largely unknown. Positron emission tomography (PET) was used to investigate verbal and spatial short-term storage (3 sec) in older and younger adults. Previous investigations with younger subjects performing these same tasks have revealed asymmetries in the lateral organization of verbal and spatial working memory. Using volume of interest (VOI) analyses that specifically compared activation at sites identified with working memory to their homologous twin in the opposite hemisphere, we show pronounced age differences in this …

Mechanism Of Triazolo-Benzodiazepine And Benzodiazepine Action In Anxiety And Depression: Behavioral Studies With Concomitant In Vivo Ca1 Hippocampal Norepinephrine And Serotonin Release Detection In The Behaving Animal, Patricia A. Broderick, Omotola Hope, Pierrot Jeannot

Publications and Research

1. Real time, in vivo microvoltammetric studies were performed, using miniature carbon-based sensors, to concurrently detect norepinephrine (NE) release and serotonin (5-HT) release, in 2 separate electrochemical signals, within CA₁ region of hippocampus in the freely moving and behaving, male, Sprague Dawley laboratory rat.

2. Concurrently, four parameters of open-field Behavior I.E. Ambulations, Rearing, Fine Movements and Central Ambulatory behavior (a measure of anxiety reduction behavior), were assayed by infrared photobeam detection.

3. Time course studies showed that the mechanism of action of the triazolobenzodiazepine (TBZD), adinazolam, (Deracyn®) is dramatically different from that of the classical benzodiazepine (BZD), diazepam …
