Sight restoration reverses blindness-induced cross-modal functional connectivity changes between the visual and somatosensory cortex at rest

Frontiers in Neuroscience, 2022
Resting-state functional connectivity (rsFC) has been used to assess the effect of vision loss on brain plasticity. With the emergence of vision restoration therapies, rsFC analysis provides a means to assess the functional changes following sight ...

The functional performance of the Argus II retinal prosthesis. [PDF]

Expert Rev Med Devices, 2014
Visual prostheses are devices to treat profound vision loss by stimulating nerve cells anywhere along the visual pathway, typically with electrical pulses. The Argus II implant, developed by Second Sight Medical Products (SSMP, Sylmar, CA, USA), targets the retina and features 60 electrodes that electrically stimulate the surviving retinal neurons.

Intraoperative OCT Imaging of the Argus II Retinal Prosthesis System. [PDF]

Ophthalmic Surg Lasers Imaging Retina, 2016
BACKGROUND AND OBJECTIVE: Optimal placement of the Argus II Retinal Prosthesis System (Second Sight Medical Products, Sylmar, CA) is critical. Intraoperative optical coherence tomography (OCT) allows for intrasurgical visualization and confirmation of array placement.

Characterization and expression analysis of gpr173a and gpr173b revealed their involvement in reproductive regulation in spotted scat (Scatophagus argus)

Aquaculture Reports, 2022
Spotted scat (Scatophagus argus) is an economically important mariculture fish worldwide. However, its latent mechanisms of reproductive regulation remain unclear. G protein-coupled receptor 173 (GPR173) is the putative receptor of phoenixin (Pnx), which

Visual and Non-Visual Navigation in Blind Patients with a Retinal Prosthesis. [PDF]

PLoS ONE, 2015
Human adults with normal vision can combine visual landmark and non-visual self-motion cues to improve their navigational precision. Here we asked whether blind individuals treated with a retinal prosthesis could also benefit from using the resultant new

Determination of the Michel Parameters rho, xi, and delta in tau-Lepton Decays with tau --> rho nu Tags [PDF]

, 1997
Using the ARGUS detector at the $e^+ e^-$ storage ring DORIS II, we have measured the Michel parameters $\rho$, $\xi$, and $\xi\delta$ for $\tau^{\pm}\to l^{\pm} \nu\bar\nu$ decays in $\tau$-pair events produced at center of mass energies in the region ...
