Thalamic microcircuitry: neurons, synapses, and circuit motifs in receptive field structure and sensory processing

Our perception of the world is first shaped by the thalamus, a structure composed of many nuclei in the center of our brains. Different nuclei hold different responsibilities - vision (dorsal lateral genicular nucleus; dLGN), audition (medial geniculate nu ...

Laser photo-detachment combined with Langmuir probe in magnetized electronegative plasma: how the probe size affects the plasma dynamic?

Ivo Furno, Riccardo Agnello

Laser photo-detachment combined with a Langmuir probe (LP) is used to diagnose negative ion properties in electronegative plasmas. The technique relies on the combined use of a laser pulse and an LP. The laser pulse converts negative ions into electron-ato ...

Optical phase contrast imaging of human retinal cells by changing the tissue refractive index

Christophe Moser, Timothé Laforest, Laura Emmanuelle Kowalczuk, Mathieu Künzi

Purpose : Based on oblique partially coherent illumination of transparent samples, we developed a simple custom Optical Phase Imaging (OPI) microscope providing a label-free, semi-quantitative phase contrast imaging. The aim of this study was to explore th ...

Single particle cryo‐EM of the complex between interphotoreceptor retinoid‐binding protein and a monoclonal antibody

Henning Paul-Julius Stahlberg, Andreas Engel

Interphotoreceptor retinoid‐binding protein (IRBP) is a highly expressed protein secreted by rod and cone photoreceptors that has major roles in photoreceptor homeostasis as well as retinoid and polyunsaturated fatty acid transport between the neural retin ...

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 ...

Transscleral optical phase imaging of the human retina

Christophe Moser, Timothé Laforest, Laura Emmanuelle Kowalczuk, Dino Carpentras

In vivo observation of the human retina at the cellular level is crucial to detect the first signs of retinal diseases and properly treat them. Despite the phenomenal advances in adaptive optics systems, clinical imaging of many retinal cells is still elus ...

In vivo evaluation of gene editing and prosthetic strategies to restore vision in small and large animal models of retinal degeneration

Paola Vagni

Inherited retinal diseases (IRDs) form a group of diverse disorders that lead to the degeneration of the light-sensing cells of the retina: the photoreceptors. IRDs are among the leading causes of blindness in working-age adults living in industrialized co ...
