Laboratory of Translational Neurogenetics

On the network level, we applied combinations of in vivo long-term time-lapse analysis and focal laser ablations to unravel a mechanism by which habenular efferent axons navigate the brain to innervate their targets.

We are now heading for a comprehensive view connecting genes to network formation and function. 
We combine genetic, transgenic, molecular and imaging methods for research on the following topics:

• How does Wnt signaling regulate neuronal diversity and left-right brain asymmetry?
• Is there a link of metabolism and neuronal development, function and/or asymmetry?
• Which senses depend on asymmetry?
• Establishment of a model for treatment for habenular network related diseases.

Group members

• Matthias Carl, PI
