Communication in the brain relies on the ability of neurons to generate electrical signals. The generation of action potentials occurs at a specialized axonal compartment, the axon initial segment. The axon initial segment is a critical checkpoint in the information flow: after integration of somato-dendritic inputs, the axon initial segment determines the neuron’s output which will be further transmitted along the axon to the next neurons in the network. The molecular composition of the axon initial segment is crucial in defining the response generated by a neuron. Recent work from my group and others have shown that the axon initial segment is highly adaptative and that this property allows neurons to tune their activity to their surrounding network. The aim of this project is to understand the molecular mechanisms controlling axon initial segment plasticity; how does this compartment reorganize in response to activity changes in various neuronal types?
In this project, you will use proteomics and transcriptomics analyses in combination with live-cell and super-resolution imaging to assess the changes in expression and dynamics of axon initial segment proteins at high spatio-temporal resolution. The work will be carried out in rodent dissociated neurons and slices.
You will be part of international research networks and exploit a variety of techniques and analysis tools available. You will be trained on site and in specialized courses on campus.
