I'm so excited that @christ3na.bsky.social 's paper describing temporal control of photoreceptor development in human organoids is out at Genes and Dev and we got the cover! genesdev.cshlp.org/content/40/1... genesdev.cshlp.org/content/40/1...

Hey, @drdorotask.bsky.social is here on Bsky! Such cool work. We think that retinas degenerate with time and that if all of us live long enough, we’ll get AMD or other neurodegenerative diseases. But Greenland sharks manage to live for hundreds of years and repair their eyes. How?

Excited to share our new work on visual information processing in the retinocollicular pathway. We discovered that while luminance responses can predict motion responses in retinal ganglion cells, this prediction does not hold in the superior colliculus cells. www.cell.com/current-biol...

It’s @petetheteapot.bsky.social at the Retinal Ganglion Cell meeting talking about his work in gene therapy targeting neuroprotection and neurodegeneration.

"All existing prosthetic vision systems — penetrating electrodes, cortical surface grids, retinal implants, optogenetics, or sensory substitution — deliver signals that differ drastically from natural retinal coding. The brain must reinterpret foreign codebooks under bandwidth and noise constraints"

It is @michelcayouette.bsky.social speaking at the Retinal Ganglion Cell Meeting.

It’s @richardevalab.bsky.social speaking at the Retinal Ganglion Cell Meeting about his work in retinal neuroprotection and optic nerve regeneration.

It’s @john-ash8831.bsky.social talking at the Retinal Ganglion Cell Meeting about his work in retinal neuroprotection with combination therapy.

Frog eye, frog eye. Can I have a confocal microscope to play on for 12 hrs a day again please? 👉👈🥺 🐸

Buenos días, ojazos 👀

A great talk by @cuilab.bsky.social at the Retinal Ganglion Cell meeting.

It’s @a-alexandris.bsky.social talking at the Retinal Ganglion Cell Meeting about his work in axonal degeneration.

Trying to find some protocols for cone isolation from frogs that don't involve transgenics or freezing. There is a surprising dearth of information out there for cone isolation? Seems to be mostly rods. Is anyone familiar with any simple-ish protocols? 🧪 👀 #xenopus

Extremely proud to share our publication on S-cone circuitry in the ground squirrel, newly available this week in PNAS. We've been staring at these reconstructions for a long time, and I'm excited for others to see the results. 1/n www.pnas.org/doi/10.1073/...

Just a heads up: I just got a phishing attempt pretending to be from the #VisualSystemDevelopment #GRC. It looked pretty convincing at first glance, so be careful!

That image is from 1961 and an idealization. Here is an actual trajectory of fixational eye movements. The dots are 2 ms apart. If a midget ganglion cell, with single-cone receptive field, fires at 100 Hz, then every spike reports about a different cone. How can we ever read anything?

#FluorescenceFriday A sky of light within ✨ This is the ganglion cell layer of the avian retina. The nerve fiber layer lies beneath like a soft green current, carrying quiet signals forward. Sometimes to see the universe with its beautiful scattered stars, one only has to look inside.

Hey folks, this is a very cool opportunity for peeps to do an amazing postdoc in Sydney, Australia in translational vision research.

Excellent work @victorcalbiagueg.bsky.social !!!

1of2) New from the ARIA lab in eLife: This article shows that it is possible to optogenetically activate single retinal ganglion cells in vivo in monkeys. This is an important step toward causal tests of the role of specific ganglion cell types in visual perception...
