  • Clinical and Computational Auditory neuroscience

    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.

  • Cochlear Neurotransmission Group

    The Cochlear Neurotransmission Group studies the generation and propagation of neural signals in 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.

  • Kata Design Studio

    We started Kata to bridge the gap between professional experiential production and neuroscience, clinical neurology, and medical hardware. We strive to build experiences and technology from the ground up, with a focus on mission, and at a level that is consistent with the best productions in the industry. We mirror the thousands of hours that go into a level design in a video game, but with the crucial difference that the focus is on the subtleties required for patient treatment or wellness. Our designs require high-frequency iterative development with patients and users in countless game-play sessions in which they provide crucial feedback. Characters have been painstakingly crafted to elicit profound emotional responses. Some of the requirements for patients or the elderly population in this space are qualitatively different from what is needed in the entertainment marketplace. That said we have also understood the critical artistic similarities.

    The core ethos of Kata is that the... challenge of complex movement has profound benefits for cognition, wellness, and brain repair. Specifically, there is growing evidence that complex motor movement can have cognitive benefits that go beyond what has been reported for exercise alone. When designing experiences to treat motor impairments after stroke, maximizing rigorous and dynamic motor input is a requirement. New interactive technologies will allow people to engage in diverse and complex motor movements, even in the home, which was previously impossible.

    Overall it has been a very exciting journey, combining art, medicine, technology, and neuroscience. We continue to build, discover, and craft immersive experiences, side by side with physicians, physical therapists, and scientists, with the common goal of pushing clinical care and wellness forward. We believe this is only possible by having a mission focused design group embedded in an academic hospital. Ultimately, we wish to scale and perfect these innovations into other hospitals. Kata is a true hybrid of academia, and industry, doing what neither can do in isolation. We hope the ethos and design philosophy behind Kata provides the impetus for its expansion, partnerships, and growth.

  • Vestibular Neurophysiology Laboratory

    The mission of the laboratory of vestibular neurophysiology is to advance the understanding of how the body perceives head motion and maintains balance - a complex and vital function of everyday life. Although much is known about the vestibular part of the inner ear, key aspects of how the vestibular receptors perceive, process and report essential information are still mysterious. Increasing our understanding of this process will have tremendous impact on quality of life of patients with vestibular disorders, who often suffer terrible discomfort from dizziness and vertigo.

    The laboratory group's basic science research focuses on the vestibulo-ocular reflexes - the reflexes that move the eyes in response to motions of the head. They do this by studying the vestibular sensors and nerve cells that provide input to the reflexes; by studying eye movements in humans and animals with different vestibular disorders, by studying effects of electrical stimulation of vestibular sensors, and b...y using mathematical models to describe these reflexes. Researchers are particularly interested in abnormalities of the brain's inability to compensate for vestibular disorders.
