Three-dimensional concentric bipolar electrodes for high resolution optic nerve stimulation

Diego Ghezzi, Eleonora Borda, Marta Jole Ildelfonsa Airaghi Leccardi, Vivien Gaillet

ASSOC RESEARCH VISION OPHTHALMOLOGY INC2021

Transient Neurovascular Interface for Minimally Invasive Neural Recording and Stimulation

Diego Ghezzi, Philippe Reymond, Laura Ferlauto, Adele Fanelli, Elodie Geneviève Zollinger

Neural interfaces are used to mitigate the burden of traumatic injuries, neurodegenerative diseases, and mental disorders. However, the transient or permanent placement of an interface in close contact with the neural tissue requires invasive surgery, pote ...

A 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 ...

Naturalistic spatiotemporal modulation of epiretinal stimulation increases the response persistence of retinal ganglion cell

Diego Ghezzi, Naïg Aurelia Ludmilla Chenais, Marta Jole Ildelfonsa Airaghi Leccardi

Objective. Retinal stimulation in blind patients evokes the sensation of discrete points of light called phosphenes, which allows them to perform visually guided tasks, such as orientation, navigation, object recognition, object manipulation and reading. H ...
