Using animal models, my research focuses on the neural basis for auditory perception, scene analysis, attention, learning, memory, audiomotor links and decision making in auditory tasks. By recording responses in multiple cortical areas in the awake, behaving ferret in different task conditions, it has been possible to study encoding of complex spectrotemporal stimuli, and trace the transformation from sound to behavioral meaning in neurons in higher auditory cortical centers and frontal cortex. Our research indicates that topdown signals can reshape cortical filters to optimize task performance in a form of rapid plasticity. In addition to behavioral, neurophysiological and neuroanatomical techniques, we are also beginning optogenetic studies to elucidate the top-down role of frontal cortex during auditory selective attention. We have also begun studies to develop the mouse model to study these issues by simultaneoulsy imaging  large neuronal ensembles in the awake mouse.
