Mark T. Nelson, PhD Professor and Chairman, Department of Pharmacology, University of Vermont Smooth Muscle Physiology/Pharmacology Dr. Nelson obtained his PhD 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, PhD Associate Professor, Department of Psychology, University of California, San Diego Integration of Molecular Genetics and Cognitive Neuroscience in Mice Dr. Anagnostaras obtained his PhD 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, PhD Professor, Department of Biological Sciences, Plymouth State University Physiological Control of Circadian Rhythms 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, PhD Associate Professor and Chair of Psychology; Director of Undergraduate Studies, University of Vermont Neurobiology of Learning, Memory and Emotion Dr. Falls obtained his PhD 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. |

Gary M. Mawe, PhD Professor, Department of Anatomy, University of Vermont Neuronal Control of Smooth Muscle Lining the Gastrointestinal and Biliary Tracts Dr. Mawe graduated with a BS, with Distinction, in Biology at the Pennsylvania State University. He received his PhD in Anatomy at The Ohio State University. During his post-doctoral studies at Columbia University, College of Physicians and Surgeons, Dr. Mawe, in collaboration with Dr. Gershon and Dr. Branchek, was the first to identify the responses of gut neurons to 5-HT 3 receptor activation, and identified the 5-HT 1P receptor that mediates serotonergic-synaptic transmission in the enteric nervous system.

Daniel N. Weber, PhD Dr. Weber examines the relationship of toxic environmental contaminants to the changes in behavior and neural development in fishes. He has a PhD (Ethology, Physiology) from the University of Wisconsin-Milwaukee and is Associate Scientist and Manager, Neurobehavioral Toxicology Facility of the Children's Environmental Health Center at the UW-Milwaukee Great Lakes WATER Institute. The mission of this NIEHS-funded research center is to develop fish and mammalian models to understand the mechanisms of environmental-based disease in children. Past research has involved studying the effects of lead on social and feeding activities, as well as locomotor behaviors in freshwater species of fish. Dr. Weber has examined changes in circadian behavioral and neurotransmitter rhythms of metal-exposed fish. Current research focuses on the effects of mercury and lead exposure on the embryonic development of neural paths that control startle responses to directional stimuli or learning and memory at various life history stages. Additionally, Dr. Weber works with state and federal natural resource managers to evaluate the effect of urban storm water runoff on the reproductive success of native fish species with the goal of developing guidelines for managing urban and urbanizing watersheds. To proceed with these behavioral experiments, Dr. Weber designs and tests new apparatuses such as those for evaluating visual and acoustical startle responses in larval and adult zebrafish as well as learning and memory assessments. |
