Department of Biology, University of Fribourg, Chemin du Musee 10, CH 1700 Fribourg, Switzerland
Curr Biol 15:982-92. 2005..Does this suggest that the larval olfactory system is built according to a different design than its adult counterpart, or is it just a miniature version thereof?..

Research Grants
- Assembly of the Central Olfactory Networks in DrosophilaLiqun Luo; Fiscal Year: 2007..Our studies will also provide insight into how olfactory information is transferred and transformed along the central pathways in the brain. ..
- Mosaic Analysis with Double Markers in MiceLiqun Luo; Fiscal Year: 2007..This method can also be used to create mouse models for human diseases such as loss of heterozygosity in cancer and neurological diseases. ..
- MECHANISMS OF NEURONAL REORGANIZATIONLiqun Luo; Fiscal Year: 2007..Thus, we believe these studies will contribute to our understanding of axon degeneration in diseases ..
- Assembly of the Central Olfactory Networks in DrosophilaLiqun Luo; Fiscal Year: 2009..In addition, knowledge of insect olfactory system organization and development can be used to help design strategies to combat malaria, transmitted by mosquitos that utilize primarily olfaction to find their mates and human host. ..
