Scheiner lab - Behavioral biology of the honeybee
Honeybees have long been model organisms for neurobiology and behavioral biology. They display an enormous plasticity in their behavior and thus provide ideal conditions for investigating underlying mechanisms of behavioral control. The complex social organisation and individual behavioral decisions are main topics of our research. We are particularly interested in the functions of neurotransmitters such as octopamine and tyramine and of their receptors. In addition, we investigate the role of protein kinases in behavioral control. A second focus of our research lies on understanding taste perception in honeybees. We use a broad spectrum of methods including behavioral observations, behavioral physiology, electrophysiology, molecular biological assays and neuroanatomy.
