PhD position: regeneration of locomotor circuits after spinal cord injury in salamanders

In mammals, voluntary locomotion is lost after full transection of the spinal cord. In salamanders, the spinal cord regenerates and the animal recovers voluntary locomotion after a few weeks. How this occurs is largely unknown. Genetic dissection of salamander neural circuits is now feasible with methods for manipulation, elimination, and visualisation of cells. Such approaches can be combined with neuroscience tools such as calcium imaging (confocal and two-photon imaging), patch-clamp electrophysiology, optogenetics, tracing and movement analysis (for review see Ryczko et al. 2020 Trends in Neurosciences, 43(11):916-930, https://doi.org/10.1016/j.tins.2020.08.006). The candidate will use these powerful approaches to dissect the organisation of salamander locomotor circuits in the intact and regenerated spinal cord. The present ERC synergy grant project will be carried out in close collaboration with modelers and roboticists who are building a detailed model of the salamander circuits (team of Pr. Auke Ijspeert, EPFL, Lausanne, Switzerland) and experts in genomics and regeneration who generate transgenic salamanders (team of Pr. Andras Simon, Karolinska Institute, Stockholm, Sweden).
