Three-dimensional multilayer concentric bipolar electrodes restrict spatial activation in optic nerve stimulation
Diego Ghezzi, Eleonora Borda, Ricardo Camilo Moreira, Marta Jole Ildelfonsa Airaghi Leccardi, Vivien Gaillet, Elodie Geneviève Zollinger
Objective. Intraneural nerve interfaces often operate in a monopolar configuration with a common and distant ground electrode. This configuration leads to a wide spreading of the electric field. Therefore, this approach is suboptimal for intraneural nerve ...
IOP Publishing Ltd2022Investigation of electrical stimulation of the optic nerve for artificial vision
Thanks to recent technological advances in microelectronics and bioengineering, it is now possible to restore lost or impaired sensory modalities by interfering the nervous system with elec-tronic devices and artificially reproducing the electrical encodin ...
EPFL2021A machine-learning algorithm correctly classifies cortical evoked potentials from both visual stimulation and electrical stimulation of the optic nerve
Diego Ghezzi, Eleonora Borda, Vivien Gaillet, Elodie Geneviève Zollinger
Objective. Optic nerve's intraneural stimulation is an emerging neuroprosthetic approach to provide artificial vision to totally blind patients. An open question is the possibility to evoke individual non-overlapping phosphenes via selective intraneural op ...
IOP PUBLISHING LTD2021Spatially selective activation of the visual cortex via intraneural stimulation of the optic nerve
Silvestro Micera, Diego Ghezzi, Fiorenzo Artoni, Paola Vagni, Vivien Gaillet, Ariastity Mega Pratiwi, Dario Lipucci Di Paola
Retinal prostheses can restore a functional form of vision in patients affected by dystrophies of the outer retinal layer. Beyond clinical utility, prostheses for the stimulation of the optic nerve, the visual thalamus or the visual cortex could also serve ...
2019Investigating Single and Multi-Channel Electrical Stimulation of the Optic Nerve for Neuroprosthetic Applications
Silvestro Micera, Diego Ghezzi, Fiorenzo Artoni, Paola Vagni, Vivien Gaillet
Here we demonstrate the ability to selectively activate different portions of the optic nerve with a novel nerve interface, the OpticSELINE, and show the possibility to improve the spatial selectivity of the electrical stimulation using current focusing ac ...
2019In vivo electrical stimulation of the optic nerve and hybrid computational model for neuroprosthetic applications
Silvestro Micera, Diego Ghezzi, Samuel Charles Antoine Gilliéron, Fiorenzo Artoni, Paola Vagni, Vivien Gaillet
Blindness affects millions of people worldwide, dramatically decreasing their quality of life. Retinal dystrophies, such as age related macular degeneration and Retinitis Pigmentosa, which are leading causes of blindness in industrialized countries, curren ...
20183D multi-layer probe for application in neuroprosthetics
Diego Ghezzi, Marta Jole Ildelfonsa Airaghi Leccardi, Vivien Gaillet, Bastien Duckert
In neuroprosthetics, prostheses with higher and denser electrodes are needed to obtain both more precise recordings and targeted stimulations. The main limit is the routing of the active sites to the electronic control unit. A solution is to place electrod ...
