(Fall semester seminars 2021 will be held via Zoom)
September 21: Ukpong Eyo, Ph.D., University of Virginia School of Medicine
Assistant Professor, Department of Neuroscience
"Microglia regulate neuron and vascular function"
Faculty Host: Karen Wilcox, Pharmacology & Toxicology
Student Host: Laura Bell
Research Summary: Our laboratory is focused on understanding how immunological pathways contribute to neurodegenerative, neurodevelopmental, mental, and behavioral disorders. We are actively investigating the cellular and molecular pathways that contribute to neuroinflammation and central nervous system (CNS)-related tissue damage. We are particularly interested in elucidating the mechanisms that regulate inflammatory cytokine production in the CNS in response to both tissue injury and CNS infection.
October 19: Lisa Giocomo, Ph.D., Stanford University
Associate Professor, Department of Neurobiology, Wu Tsai Neuroscience Institute
"Multiple maps for navigation"
Faculty Host: Jim Heys, Neurobiology
Student Host: Erin Bigus
Research Summary: The Giocomo Lab integrates electrophysiology, behavior, imaging, gene manipulations and computational modeling to study how single-cell biophysics and network dynamics interact to mediate spatial memory and navigation.
November 16: Lindsay Shwarz, Ph.D., St. Jude Children's Research Hospital
Faculty, Department of Developmental Neurobiology
"Diversity in norepinephrine neural circuits"
Faculty Host: Megan Williams, Neurobiology
Student Host: Arnulfo Tuñon-Ortiz
Research Summary: Our lab is interested in identifying and characterizing novel mechanisms that regulate the function of NE circuits in vivo, towards understanding how these brain circuits help to generate distinct behaviors depending on the situation.
January 18: Richard Edden, M.Sc., Ph.D., John Hopkins University
Associate Professor, Department of Radiology, John Hopkins Science of Learning Institute
"Advanced Edited Magnetic Resonance Spectroscopy"
Faculty Host: Brian Mickey, Psychiatry
Student Host: Keith Jones
Research Summary: Dr. Edden’s research is concerned with both the development of new MRS methods and the application of existing methods to investigate the brain. One technical area of my research is the behaviour of coupled spin systems (such as lactate, citrate, GABA and Glx) during localised spectroscopy experiments; in particular, considering the interplay between finite-bandwidth slice-selective pulses and the chemical shift difference between coupled spins. The result of coupling evolution can change significantly across selected volumes, resulting in loss of signal intensity.
February 15: Karin Peterson, Ph.D., National Institute of Allergy and Infectious Diseases
Chief, Neuroimmunology Unit
"Neuropathogenesis of Orthobunyaviruses"
Faculty Host: Mario Capecchi, Human Genetics
Student Host: Kayla Eschenbacher
Research Summary: Virus infection of the Central Nervous System (CNS) can lead to damage to neurons and the development of neurological disease. Multiple cell types in the CNS are activated during virus infection and have important roles in regulating viral pathogenesis. The goal of our laboratory is to examine the interactions between the immune and nervous systems in regulating viral pathogenesis with the ultimate goal of identifying targets for therapeutic treatment of viral-mediated neurological diseases. We primarily utilize two different models of viral infections that mediate neuronal damage via either direct or indirect mechanisms. One model utilizes La Crosse Virus (LACV), a bunyavirus that is one of the leading causes of pediatric viral encephalitis in the United States. LACV induces neuronal apoptosis by directly infecting neurons. The other model of viral neuropathogenesis is a retrovirus model, where microglia and macrophages are the primary cell type infected in the CNS. In this model system, the damage to neurons is indirect. Our work with these viruses has identified mechanisms of both neuronal damage and neuronal protection that are mediated by specific interactions of the immune system with cells of the central nervous system. We are currently examining the regulation of these pathways and mechanisms in order to inhibit viral pathogenesis in the CNS.
March 15: Kate Wassum, Ph.D., University of California, Los Angeles
Associate Professor, Department of Psychology
"Neural circuitry of reward learning and pursuit"
Faculty Host: Moriel Zelikowsky, Neurobiology
Student Host: Kevin Sattler
Research Summary: Associative memories underlie a large majority of our emotions, motivations, and decisions. We strive to understand how these memories are formed and stored in the brain and how they combine with one’s current state to dictate behavior. Our ultimate goal is to facilitate the understanding and treatment of the mental illnesses, such as drug and alcohol addiction, that arise from disruptions in these neural systems.
April 19: Dayu Lin, Ph.D., New York University Langone Health
Associate Professor, Departments of Psychiatry and Neuroscience & Physiology
"Neural mechanisms of aggression"
Faculty Host: Moriel Zelikowsky, Neurobiology
Student Host: Rachel Gatlin
Research Summary: Social behaviors such as mating, fighting, defense, predation and parenting, are innate, indispensable and ubiquitous across the animal kingdoms. Research in our laboratory centers on understanding the neural circuits underlying these powerful behaviors in a genetically tractable model system, mice. We are interested in investigating how the sensory information is relayed, integrated, extracted and diverged to ultimately cause the behavioral output. Various genetic engineering, tracing, functional manipulation, in vivo electrophysiological recording and computational tools are combined to dissect the neural circuits in a great detail.
