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 ...

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
