DESCRIPTION:Prof. Diego Ghezzi\, Institute of Bioengineering and Center fo
 r Neuroprosthetics\, EPFL\, Lausanne (CH)\nBIOENGINEERING SEMINAR\n\nAbstr
 act:\nNeuroprosthetics is an interdisciplinary area of research bringing t
 ogether engineering\, computer science and medicine to treat neurological 
 and psychiatric disorders. In neuroprosthetics\, neurostimulation plays a 
 crucial role\, and innovation in implantable neurostimulation devices is i
 mportant to address unmet clinical needs. My laboratory tackled this chall
 enge by developing innovative implantable neural prostheses for blindness.
 \n\nIn this seminar\, I will present my group's research achievements in d
 esigning and validating novel visual prostheses for artificial vision.\n\n
 First\, I will describe a novel retinal implant. POLYRETINA is a high-dens
 ity and wide-field photovoltaic prosthesis that contains ten thousand phot
 ovoltaic pixels covering a visual angle of 43 degrees. High-resolution sti
 mulation combined with the wide retinal coverage make POLYRETINA a prosthe
 sis that could offer artificial vision for reliable object recognition\, o
 bstacle detection and safe ambulation\, crucial abilities for totally blin
 d people to be independent.\n\nIn the second part of the talk\, I will des
 cribe another novel visual prosthesis based on intra-neural stimulation of
  the optic nerve. OpticSELINE is an intraneural 3D electrode array capable
  of selectively activating the optic nerve fibres to induce artificial vis
 ion. This technology is essential for patients not eligible to be implante
 d with retinal prosthesis because of exclusion criteria. I will present th
 e results from our in vivo preclinical trial in large animals.\n\nLastly\,
  I will anticipate how our current and future research will lead to novel 
 neuroprosthetics approaches for blindness and other neurological disorders
 .\n\nBio:\nProf. Diego Ghezzi holds the Medtronic Chair in Neuroengineerin
 g at the School of Engineering at the Ecole Polytechnique Fédérale de La
 usanne (LNE). He received his M.Sc. in Biomedical Engineering (2004) and P
 h.D. in Bioengineering (2008) from Politecnico di Milano (Italy). From 200
 8 to 2013\, he completed his postdoctoral training at Istituto Italiano di
  Tecnologia in Genova (Italy) at the Department of Neuroscience and Brain 
 Technologies\; where he was promoted to Researcher in 2013. In 2015\, he w
 as appointed as Tenure-Track Assistant Professor of Bioengineering at the 
 EPFL Center for Neuroprosthetics and Institute of Bioengineering.\n\n\nZoo
