As peripheral sensory organs, insect antenna detect multimodal environmental information. The receptor neurons that path information to the brain code for instance auditory, olfactory and hygro-thermosensitive information. Especially for mate recognition and selection during courtship, female Drosophila uses near field sound information and olfactory cues of the male. How processing of these different modalities interferes in the brain is unknown and subject of the planned project.
The goal of our PhD project is to examine bimodal processing of acoustic and olfactory information in the insect brain (bushcrickets/katydids and Drosophila). This study combines a broad spectrum of methodological approaches, starting from mechanical measurements of the antennal motion in Drosophila by optical coherence measurements  up to neurophysiological and functional imaging techniques . We aim to identify interaction and modulatory processes of these sensory modalities in the insect brain, which also offers the use of neurogenetic tools.
We are looking for a highly motivated and creative candidate with training in ear mechanics, neurophysiology or neurogenetics. Experiences with insect research is useful. A master’s degree in Neuroscience, Biology or related discipline is required for this PhD position.
