My research focuses on the neuronal basis of the sky-compass system in honeybees. So far, their astonishing abilities regarding orientation and navigation using sky-compass signals has been studies mainly in behavioral exeriments. The physiology of the neuronal system providing signal processing and behavioral output is currently largely unknown.

In my project I therefore try to uncover the physiology of neurons that are involved in the sky-compass system using calcium-imaging. To this end I inject calcium indicators into specific visual centers and record the calcium signals in living, behaving honeybees.
