Olfaction

We investigate olfactory processing and odor-guided behavior in insects. In collaboration with our experimental partners we analyze neurophysiological data to elucidate the olfactory code at different levels of the olfactory system. In computational and mathematical models we study efficient and sparse odor coding along the olfactory pathway. We are particularly interested in how the system processes olfactory input under natural stimulus conditions, i.e. for temporally and spatially dynamic stimuli. Moreover we study the formation of olfactory memories in the honeybee.

Funding

Funding is provided by the German Research Foundation (DFG) within the priority program Integrated Analysis of Olfaction (SPP 1392) and by the German Ministry of Education and Research within the Bernstein Focus Neuronal Basis of Learning: Insect inspired robots - The role of memory in decision making. Additional funding was received by the Volkswagen Stiftung.
