Sensory input across modalities is highly dynamic and continuously confronts the brain with the task of making sense of the external world. In our group at the IEECR, we study olfaction as a key sense that many species depend on for survival. Olfactory cues can be especially useful in situations such as locating food sources, mating partners or avoiding predator encounters. Natural odours form temporally complex plumes that provide information over a large range of distances, in the absence of visual cues. The complex temporal dynamics of odour plumes carry spatial information about the odour landscape. Our lab concentrates on understanding how mammals use this spatial information to navigate their environment at the cellular, circuit, and behavioural level. Using advanced opto- and electrophysiological methods and innovative quantitative behavioural paradigms, we aim to unravel how the brain encodes the dynamic external world and how this gets translated into behaviour.
