Valproate reduces retinal ganglion cell apoptosis in rats after optic nerve crush
The retinal ganglion cells of the optic nerve have a limited capacity for self-repair after injury. Valproate is a histone deacetylase inhibitor and multitarget drug, which has been demonstrated to protect retinal neurons.

Do retinal ganglion cells project natural scenes to their principal subspace and whiten them? [PDF]
Several theories of early sensory processing suggest that it whitens sensory stimuli. Here, we test three key predictions of the whitening theory using recordings from 152 ganglion cells in salamander retina responding to natural movies. We confirm the previous finding that firing rates of ganglion cells are less correlated compared to natural scenes ...

Retinal adaptation and invariance to changes in higher-order stimulus statistics [PDF]
Adaptation in the retina is thought to optimize the encoding of natural light signals into sequences of spikes sent to the brain. However, adaptation also entails computational costs: adaptive code is intrinsically ambiguous, because output symbols cannot be trivially mapped back to the stimuli without the knowledge of the adaptive state of the ...

Mood, the Circadian System, and Melanopsin Retinal Ganglion Cells.
The discovery of a third type of photoreceptors in the mammalian retina, intrinsically photosensitive retinal ganglion cells (ipRGCs), has had a revolutionary impact on chronobiology.

Targeting retinal ganglion cell recovery [PDF]
Accumulating evidence from experimental and clinical studies suggest that retinal ganglion cells at least in the earlier stages of glaucoma have the capacity to recover function following periods of functional loss. The capacity for recovery may be negatively impacted by advancing age but can be boosted by interventions such as diet restriction and ...

Single-cell RNA sequencing analysis of the retina under acute high intraocular pressure
High intraocular pressure causes retinal ganglion cell injury in primary and secondary glaucoma diseases, yet the molecular landscape characteristics of retinal cells under high intraocular pressure remain unknown. Rat models of acute hypertension ocular

Neuroprotection of Retinal Ganglion Cells [PDF]
Therapeutic efforts for treatment of glaucoma have focused on reduction of intraocular pressure as the main objective. In clinical practice, intraocular pressure (IOP) control has been expected to slow or arrest the glaucoma progression. However, clinicians have been confronted with significant glaucoma progression even when achieving control of ...

Dendritic and axonal targeting patterns of a genetically-specified class of retinal ganglion cells that participate in image-forming circuits. [PDF]
BackgroundThere are numerous functional types of retinal ganglion cells (RGCs), each participating in circuits that encode a specific aspect of the visual scene.
