The nervous system modulates and mediates information propagation via both electrical and chemical signals. Disruption to these signalling pathways can lead to pathologies such as epilepsy, Parkinson’s disease or depression. Neural stimulation, particularly of the vagus nerve, located in the neck, has proven to be beneficial for patients whose symptoms are not or improperly treated by conventional medications.
Implantable neurostimulators are currently delivering electrical impulses using standard metal generators and wires that go under a patient’s skin and connect to the nerves or the brain. By using transparent casing and optical fibers - instead of metal parts - the NAOS project aims at developing innovative implantable devices that will advance existing neural stimulation treatments, hence improving patients’ quality of life and paving the way to new personalized therapies.
