Neural Mechanisms in Complex Sound Processing

We study neural mechanisms underlying complex sound processing in the auditory system of echolocating bats, which are known to have excellent hearing. At the same time many features of their sonar sounds are analogous to other communication sounds including human speech. Physiological studies in bats can therefore provide insight into how speech-like sounds are encoded in the auditory system. The major focus of our research is to examine mechanisms responsible for auditory neuron response selectivity to different parameters of complex sounds. Among different neurophysiological approaches we use in our laboratory, our primary electrophysiological technique involves intracellular recording of single auditory neurons in awake bats in response to sounds.
