My research interest is the neuronal basis of behavior with a main focus on mechanisms of developmental and adult plasticity in the brain (e.g. olfactory and visual neuropils) of insects. Social insects are favorable model systems to study these aspects because of a multitude of sensory and behavioral adaptations. In order to understand how the nervous system is able to process and store sensory information, knowledge of the connections and properties of neurons within microcircuits is required. To investigate synaptic structural plasticity in the insect brain, I mainly use neuroanatomical techniques (immunocytochemistry, serial 3D electron microscopy). Current research projects are:
Current research projects are
- neuronal connectivity of individual microcircuits in the mushroom-body calyx (honeybee)
- age-releated structural plasticity of visual and olfactory centers in the brain (bumble bee)
- structural plasticity in microglomerular synaptic circuits of the mushroom-body after sensory experience (honeybee)
