Brain stimulation methods have shown great promise as a treatment for multiple brain disorders. These methods suffer however from limitations, including poor spatial resolution, which makes it impossible to target specific neuronal circuits, and poorly understood neurophysiological bases, which raises reproducibility concerns. Together with European colleagues, we are developing and testing a groundbreaking method of mechanogenetic stimulation in an interdisciplinary project called SynMech
. Our approach is based on the application of functionalized biocompatible magnetic nanoparticles and bioengineered synaptic mechano-sensors that synergistically integrate at specific synaptic connections to repair dysfunctional brain circuits in response to externally applied magnetic fields.
Your role will be to assess the effects of this novel mechanogenetic toolkit on different neurobehavioral, neurophysiological and neuroimaging markers in rodent models of stroke. You will apply the novel experimental treatment, involving intracortical gene and nanoparticle delivery, followed by repetitive transcranial magnetic stimulation (rTMS) in mouse and/or rat models of stroke, together with a biotechnician. You will execute serial in vivo functional MRI, optical imaging, electrophysiological recordings and behavioral tests. You will analyze and correlate multiparametric datasets, which you will frequently discuss with colleagues internally, as well as with international partners within the SynMech consortium.
