Batlab studies echolocation to learn how animals 'see' with sound

Neuroscientist Cindy Moss is investigating how animals use sensory information to guide their behavior. Her team at Johns Hopkins University's "Batlab" is currently focused on bat echolocation -- high frequency sonar calls a bat uses to determine the location of objects in its environment. With support from the National Science Foundation, the group aims to better understand how these highly specialized creatures perceive and navigate their world, and in turn, learn more about how humans do it. Moss says what's great about studying bat brains is the animal essentially broadcasts its thought processes as it goes about its natural behaviors, such as hunting for its next meal. "Processing of the sound information once it returns to the bat's ears is comparable to information that another animal may get directly from the environment, for example, light that is processed through the visual system," explains Moss. "One of the very lofty goals in neuroscience is to understand brain function. What does that mean? It means activity of the brain in the context of real-world behaviors. The bat, as an active sensing animal that produces the sounds that guide its behavior, provides us with a window to information processing." While humans and bats engage the world in different ways, both are mammals, and thus share a lot in common. Moss and her team's discoveries will not only help reveal new information unique to bats, but also characteristics of the nervous system of all mammals -- including humans.
