To make optimal decisions and adapt successfully to our environments, we need to make use of all the sensory cues we can detect (e.g., visual, olfactory, tactile, noxious), which initially arrive through selective channels. A central question in neuroscience concerns how nervous systems transform these originally segregated inputs into holistic multisensory representations, and how they use these representations to guide the selection of actions. Our research is focused on discovering the fundamental circuit principles that underlie these processes. To tackle this challenge, we have been studying escape behaviors in larval Drosophila melanogaster.
