    Principal Investigator:
    Solange Brown, M.D., Ph.D.
    Neuroscience

    The Brown Lab is focused on the function of the cerebral cortex in the brain, which underlies o...ur ability to interact with our environment through sensory perception and voluntary movement. Our research takes a bottom-up approach to understanding how the circuits of this massively interconnected network of neurons are functionally organized, and how dysfunction in these circuits contributes to neurodegenerative diseases like amyotrophic lateral sclerosis and neuropsychiatric disorders, including autism and schizophrenia. By combining electrophysiological and optogenetic approaches with anatomical and genetic techniques for identifying cell populations and pathways, the Brown Lab is defining the synaptic interactions among different classes of cortical neurons and determining how long-range and local inputs are integrated within cortical circuits. In amyotrophic lateral sclerosis, corticospinal and spinal motor neurons progressively degenerate. The Brown Lab is examining how abnormal activity within cortical circuits contributes to the selective degeneration of corticospinal motor neurons in an effort to identify new mechanisms for treating this disease. Abnormalities in the organization of cortical circuits and synapses have been identified in genetic and anatomical studies of neuropsychiatric disease. We are interested in the impact these abnormalities have on cortical processing and their contribution to the disordered cognition typical of autism and schizophrenia. view more

  • Chordoma Lab

    Lab Website

    Chordoma research is led by a comprehensive team including Gary Gallia, M.D., director of the N...eurosurgery Skull Base Tumor Center. The laboratory focuses on developing new therapies for brain and skull base tumors, and has established the first primary skull base chordoma xenograft mouse model. The team is also exploring high throughput drug screening using the chordoma model, and the molecular pathways responsible for tumor maintenance and growth. view more

  • Christopher Potter Lab

    Lab Website
    Principal Investigator:
    Christopher Potter, Ph.D.
    Neuroscience

    The Christopher Potter Lab functions at an intersection between systems and cellular neuroscien...ce. 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 Drosophila melanogaster and human malaria vector Anopheles gambiae. view more

  • Clinical and Computational Auditory neuroscience

    Lab Website
    Principal Investigator:
    Dana Boatman, Ph.D.
    Neurology

    Our laboratory investigates the neural bases of sound processing in the human brain. We combine... electrophysiology recordings (intracranial, scalp), behavioral paradigms, and statistical modeling methods to study the cortical dynamics of normal and impaired auditory perception. We are interested in measuring and modeling variability in spatiotemporal cortical response patterns as a function of individual listening abilities and acoustic sound properties. Current studies are investigating the role of high-frequency (>30 Hz) neural oscillations in human auditory perception. view more

  • Cochlear Neurotransmission Group

    Lab Website

    The Cochlear Neurotransmission Group studies the generation and propagation of neural signals i...n the inner ear. Our laboratories use biophysical, electrophysiological, molecular biological and histological methods to determine fundamental molecular mechanisms by which neurotransmitters are released from primary sensory cells ('hair cells') to excite second order neurons carrying information to the brain. We apply these same techniques to study inhibitory feedback produced by brain neurons that project to and regulate the sensitivity of the cochlea.

  • 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 u...nderstand 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. view more

  • Courtney Robertson Lab

    Lab Website

    Work in the Courtney Robertson Lab is focused on identifying interventions that could minimize ...the neurological deficits that can persist after pediatric traumatic brain injury (TBI). One study used a preclinical model to examine potential disruption of mitochondrial function and alterations in cerebral metabolism. It was found that a substantial amount of mitochondrial dysfunction is present in the first six hours after TBI. In addition, we are using nuclear magnetic resonance spectroscopy to evaluate global and regional alterations in brain metabolism after TBI. We're also collaborating with researchers at the University of Pennsylvania to compare mitochondrial function after head injury in different clinically relevant models. view more
