New paper presenting rather compelling evidence that the stem-vertebrate Haikouichthys had paired lateral and supranumerary medial eyes (!!!), and proposing that the medial eyes may have deep homology with the pineal and parapineal organs.

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?

"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"

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

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?

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.
