    Collapse Overview 
    Collapse overview
    We study mechanosensory signaling by the inner ear. We focus on the mouse utricle, where we have access to mechanosensitive receptor cells and primary afferent neurons. In this simple circuit we can address fundamental neurobiological questions, such as mechanotransduction, the nature of a simple sensory map, how transmission occurs across unique calyceal synapses, and how different kinds of information are encoded in the spike rate and timing of primary afferent neurons.
