Major neurotech hub in Milan announced
Associação Alberto Santos Dumont para Apoio à PesquisaBusiness Announcement
The IRCCS San Raffaele Hospital and the Vita-Salute San Raffaele University announced the launch of a long-term partnership with the recently established Nicolelis Institute for Advanced Brain Studies of the Brazilian Alberto Santos Dumont Association for Research Support (AASDAP, www.aasdap.org.br) aimed at creating a state-of-the-art Neurotech Hub on their campus in the city of Milan. Resulting from a two-year planning process, that included the development of a comprehensive Master Plan, the San Raffaele Neurotech Hub will be the first initiative of this kind in Europe focused on deploying large-scale modern neurotechnologies and neurorehabilitation protocols, based on the employment of a novel and generic non-invasive brain-machine interface (nBMI) approach (Figure 1). This nBMI will serve as the foundation of multiple neurorehabilitation protocols and therapies targeting patients suffering from a variety of neurological disorders, such as spinal cord injury, Parkinson’s disease, stroke, multiple sclerosis, and chronic epilepsy.
