Three-dimensional multilayer concentric bipolar electrodes restrict spatial activation in optic nerve stimulation

Diego Ghezzi, Eleonora Borda, Marta Jole Ildelfonsa Airaghi Leccardi, Vivien Gaillet, Elodie Geneviève Zollinger, Ricardo Camilo Moreira

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 ...

POLYRETINA restores light responses in vivo in blind Gottingen minipigs

Diego Ghezzi, Marta Jole Ildelfonsa Airaghi Leccardi, Paola Vagni, Elodie Geneviève Zollinger, Golnaz Sherafatipour, Charles-Henri Puncho Jérôme Vila

Retinal prostheses hold potential for artificial vision in blind people. Here, authors show that POLYRETINA, a large and high-density photovoltaic epiretinal device, restores light-evoked cortical responses in blind Gottingen minipigs at safe irradiance le ...

Conformable neural interface based on off-stoichiometry thiol-ene-epoxy thermosets

Diego Ghezzi, Eleonora Borda, Danashi Imani Medagoda, Marta Jole Ildelfonsa Airaghi Leccardi, Elodie Geneviève Zollinger

Off-stoichiometry thiol-ene-epoxy (OSTE+) thermosets show low permeability to gases and little absorption of dissolved molecules, allow direct low-temperature dry bonding without surface treatments, have a low Young's modulus, and can be manufactured via U ...

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 ...

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 ...

All-polymeric transient neural probe for prolonged in-vivo electrophysiological recordings

Diego Ghezzi, Laura Ferlauto, Paola Vagni, Adele Fanelli, Elodie Geneviève Zollinger

Transient bioelectronics has grown fast, opening possibilities never thought before. In medicine, transient implantable devices are interesting because they could eliminate the risks related to surgical retrieval and reduce the chronic foreign body reactio ...

Photovoltaic organic interface for neuronal stimulation in the near-infrared

Diego Ghezzi, Naïg Aurelia Ludmilla Chenais, Marta Jole Ildelfonsa Airaghi Leccardi, Laura Ferlauto, Elodie Geneviève Zollinger

Organic materials, such as conjugated polymers, are attractive building blocks for bioelectronic interfaces. In particular, organic semiconductors show excellent performance in light-mediated excitation and silencing of neuronal cells and tissues. However, ...
