  • Research Overview (from former web page):

    Research laboratories in the Rotary Hearing Center in Vancouver Hospital and Health Science Center, UBC site, have a focus on neural mechanisms for sound coding. Of special interest are the contributions of intrinsic membrane properties and synaptic mechanisms to the generation of central sensory signals. Methods include patch clamp, intra- and extra-cellular recording from isolated neurons, brain stem slices and intact animals. We are interested in the decoding of sound in the time/frequency domain, for example, during musical pitch perception in plastic adaptation of directional hearing. Most studies involve basic bench science, although clinical work in connection with cochlear implants and binaural hearing aids is pursued as well.

    We also maintain an interest in neuronal properties responsible for the plasticity in the vestibulo-ocular reflex. Generally, our in vitro studies are designed to illuminate functions of the whole organism.

    Work is done in five laboratories equipped for neurophysiological and neuroanatomical techniques. Desk space and financial support for selected students may be available. Research training in the Center prepares the student for careers in the Neurosciences both in an academic setting and in the Clinic. Like most laboratories, we are fully integrated in the Clinician Scientist Training Program, UBC.
