  • Alex Kolodkin Laboratory

    Principal Investigator:
    Alex Kolodkin, Ph.D.
    Neuroscience

    Research in the Alex Kolodkin Laboratory is focused on understanding how neuronal connectivity is established during development. Our work investigates the function of extrinsic guidance cues and their receptors on axonal guidance, dendritic morphology and synapse formation and function. We have investigated how neural circuits are formed and maintained through the action of guidance cues that include semaphorin proteins, their classical plexin and neuropilin receptors, and also novel receptors. We employ a cross-phylogenetic approach, using both invertebrate and vertebrate model systems, to understand how guidance cues regulate neuronal pathfinding, morphology and synaptogenesis. We also seek to understand how these signals are transduced to cytosolic effectors. Though broad in scope, our interrogation of the roles played by semaphorin guidance cues provides insight into the regulation of neural circuit assembly and function. Our current work includes a relatively new interest in ...understanding the origins of laminar organization in the central nervous system. view more

  • Christopher Potter Lab

    Principal Investigator:
    Christopher Potter, Ph.D.
    Neuroscience

    The Christopher Potter Lab functions at an intersection between systems and cellular neuroscience. We are interested in how neurons and circuits function in the brain to achieve a common goal (olfaction), but we also develop, utilize and build tools (molecular and genetic) that allow us to directly alter neuronal functions in a living organism. The specific focus of my laboratory is to understand how the insect brain receives, interprets, and responds to odors. Insects rely on their sense of smell for all major life choices, from foraging to mating, from choosing where to lay eggs to avoiding predators and dangers. We are interested in understanding at the neuronal level how odors regulate these behaviors. Our long-term aim is to apply this knowledge to better control insects that pose a threat to human health. Our general approach towards achieving this goal is to develop and employ new genetic methods that enable unprecedented control over neural circuits in both the model organism D...rosophila melanogaster and human malaria vector Anopheles gambiae. view more

  • Cohen Lab

    Lab Website
    Principal Investigator:
    Jeremiah Cohen, Ph.D.
    Neuroscience

    The Cohen Lab studies neural circuits underlying reward, mood and decision making. We seek to understand how neural circuits control fundamental mammalian behaviors. Many disorders, including depression, schizophrenia, drug addiction and Parkinson's disease, appear to involve dysfunction of monoaminergic signaling. Using cell-type-specific tools and well-controlled behavioral tasks in mice, we aim to understand the function of monoaminergic circuits in behavior. We hope these basic discoveries will lead to an understanding of the biology of the brain and better treatments for disorders of the brain.

  • Kristina Nielsen Laboratory

    Lab Website
    Principal Investigator:
    Kristina Nielsen, Ph.D.
    Neuroscience

    The Kristina Nielsen Laboratory investigates neural circuits in the visual cortex that are responsible for encoding objects to understand how the visual system performs object recognition. We aim to reveal the fine-scale organization of neural circuits, with an emphasis on higher-level visual areas. We use two-photon microscopy to perform high-resolution functional imaging of visual areas in the non-human primate. We also investigate how the function of higher visual areas changes over the course of brain development in ferrets, by measuring the activity of single neurons in these areas, as well as determining the animal's visual capabilities at various developmental stages. In both types of investigations, we also rely on detailed anatomical techniques to precisely observe how the function of neuronal circuits is related to their structure.

  • Marshall Shuler Laboratory

    Lab Website
    Principal Investigator:
    Marshall Shuler, Ph.D.
    Neuroscience

    The Marshall Shuler Laboratory aims to understand the means by which brain reward systems convey reward value, expectancy, quality, probability and utility, and the rules by which such activity is used to affect synaptic weight within brain networks to encode stimulus-action associations. We use an interdisciplinary approach combining multisite recordings of neural activity, targeted pharmacological manipulation, viral-mediated gene transfer and behavior to study the neural mechanisms of reward-based interval learning in the primary visual cortex.

    Principal Investigator:
    Jeffrey Mumm, Ph.D.
    Ophthalmology

    The Mumm Lab research goal is to understand how neural circuits are formed, how they function, and how they can be regenerated, to develop new therapies for retinal regeneration. An emphasis is placed on translating what can be learned in regenerative model systems to develop novel therapies for stimulating dormant regenerative capacities in humans, utilizing zebrafish, due to significant advantages afforded by this species.
