We conduct comparative and integrative research to advance our knowledge of the neural mechanisms of acoustic communication. We have the opportunity to compare a variety of bat species along a gradient of behavioral, ecological, or physiological traits, and to mice. There are >130 bat species distributing in China. Moreover, we have the opportunity to combine a variety of experimental approaches, including sound recording and playbacks, psychophysics, neurophysiology, and modeling, for integrative research. Below we provide a brief introduction to the varying approaches that we employ regularly in our research.
