Mark T. Nelson, Ph.D.
Professor and Chairman, Department of Pharmacology, University of Vermont
Smooth Muscle Physiology/Pharmacology

CURRICULUM VITAE

Dr. Nelson obtained his Ph.D. in 1980 studying Neural Sciences at Washington University, St. Louis, MO. The overall goal of the research in Dr. Nelson's laboratory is to understand the control of smooth muscle cell function by the cell membrane. A combined approach, utilizing single cell isolation, single channel and macroscopic recording techniques, intracellular calcium and calcium spark measurements using conventional fluorescent imaging techniques, laser scanning, and confocal microscopy, diameter and membrane potential measurements in intact pressurized arteries, and expression of ion channels, is used to examine the properties of calcium and potassium channels and ryanodine-sensitive calcium release channels. Calcium and potassium channels are the sites of action of several types of drugs that are used to treat cardiovascular disorders such as hypertension and angina. To understand the mechanism of action of these important drugs, the effects of these agents on calcium and potassium channel behavior are being investigated.

Dr. Nelson is considered one of the world's leading experts in smooth muscle function, and has authored well over 125 peer-reviewed manuscripts. His publications are often hailed as landmarks in the field and are frequently used for teaching purposes in graduate courses throughout the world. Many of his publications have topped several hundred citations. Dr. Nelson's classic 1989 Science paper entitled "Hyperpolarizing vasodilators activate ATP-sensitive K+ channels in arterial smooth muscle" currently stands at well over 1,000 citations. A recent survey of the prestigious journal "The American Journal of Physiology Cell Physiology" indicates that five out of the top 20 cited publications in this journal derive from the Nelson Laboratory at The University of Vermont. Dr. Nelson is currently ranked at number 26 in the world in the "Top Ranked Researchers" list published by IonChannels.org.



Stephan G. Anagnostaras, Ph.D.
Assistant Professor, Department of Psychology, University of California, San Diego

Integration of Molecular Genetics and Cognitive Neuroscience in Mice

CURRICULUM VITAE

Dr. Anagnostaras obtained his Ph.D. in Psychology in the laboratory of Dr. Michael Fanselow at the University of California, Los Angeles studying the neural basis of Pavlovian fear conditioning. After completing his graduate studies, Dr. Anagnostaras went on to train as a Postdoctoral Fellow in the laboratory of Professor Alcino Silva at UCLA.  He is a well-respected young scientist and already has several high-impact publications in the field. He has taught undergraduate- and graduate-level courses in the Neurosciences, as well as serving as Course Organizer for the Cold Spring Harbor Laboratory Summer Course on Mouse Behavioral Analysis.

The general aim of Dr. Anagnostaras' research is to combine the molecular-genetic, systems, and cognitive-behavioral levels to understand how the brain produces behavior and cognition. A major emphasis in this endeavor is bridging systems and molecular approaches using hippocampus-dependent learning, in particular, learning about context. The hippocampal-neocortical memory system offers an excellent opportunity in which the molecular and cognitive levels may be first plainly joined. Long-term objectives of Dr. Anagnostaras' research are to advance our understandings of the mechanisms of memory, cognition, and drug addiction.



Chris C. Chabot
Professor
Department of Biological Sciences
Plymouth State University

Physiological Control of Circadian Rhythms

CURRICULUM VITAE

Dr. Chabot obtained his PhD from the University of Virginia. The overall focus of his research is the physiological control of circadian rhythms in animals. He investigates the role of neural and hormonal factors as well as the interaction of the circadian clock with various behavioral and physiological outputs using several species of birds, mammals, and marine invertebrates. . Locomotor activity is often used as a dependent measure because it is a convenient output from the clock and it is easy to measure.

Circadian rhythms are controlled by an internal clock and are molecular, physiological or behavioral events that occur at a frequency of about once/day. These rhythms are ubiquitous among eukaryotic organisms from single-cell organisms to worms to insects to crustaceans to vertebrates and everything in between. This ubiquity suggests that having a circadian clock helps organisms to anticipate and synchronize to daily environmental changes and is of tremendous adaptive advantage.

Dr. Chabot maintains an active research lab involving primarily undergraduate students from the classes he teaches. He continues to attract students to his courses and labs due to his strong commitment to his students and his excellence in teaching. Dr. Chabot instills in his students the importance of critical thinking and the process of doing science, encouraging them to develop their questions and then to come up with ways with which they can attempt to answer them.

William A. Falls, Ph.D.
Associate Professor and Chair of Psychology; Director of Undergraduate Studies, University of Vermont
Neurobiology of Learning, Memory and Emotion

CURRICULUM VITAE

Dr. Falls obtained his Ph.D. from Yale University in 1993. Research in the Falls Lab is focused on examining the neurobiology of learning, memory and emotion. We utilize Pavlovian fear conditioning procedures in rats and mice to examine the neural systems involved in the acquisition, expression and inhibition of conditioned fear. Fear is measured in our laboratory using the fear-potentiated startle paradigm. In the fear-potentiated startle paradigm conditioned fear is assessed by measuring the amplitude of acoustic startle in the presence and absence of a fear-eliciting stimulus. Conditioned fear is operationally defined as elevated startle amplitude in the presence versus the absence of the fear-eliciting stimulus. Pavlovian conditioned fear procedures are thought to model many aspects of fear and anxiety in humans. Indeed, phobias and posttraumatic stress disorder are thought to reflect pathological fear responses acquired through Pavlovian conditioning. Individuals with these disorders exhibit exaggerated fear in certain situations (i.e., in the presence of the phobic stimulus) that may reflect aberrant activity in the neural circuits responsible for the acquisition, expression or inhibition of fear. Thus, by examining these neural systems we will better understand the etiology of these disorders and may begin to develop new and more effective treatments.
