Motoneurons and synaptic partners (MotoPSyn)
Our goal is to decipher the impact of the sensory-motor environment on both the global motor physiology and the possible development of motoneuronal pathologies. Using various animal models, including invertebrates, amphibians, rodents and humans that are complementary and offer specific opportunities, our research aims principally at understanding the fundamental processes of motoneuron development and motor functions physiology in a context of permanent interactions between single neurons, neuronal networks and sensory information. Specific projects focusing on various developmental and motor pathologies (ALS, ASS, vestibulopathies) are also conducted.
