#Zebrafinch retina stained with a calcium marker, revealing a tightly layered neural map beneath a simple looking tissue sheet.
Built for life in bright open Australian habitats, their visual system is tuned for speed, precision, and rapid decision making.

Back again with another #FluorescenceFriday retina post because the zebra finch retina still looks unreal under the microscope.
A tiny layered neural circuit built for fast and precise vision in these small #songbirds.

Looks like a cosmic explosion… but it’s actually a #zebrafishretina 🔬

For today’s #FluorescenceFriday, the #rods clearly chose chaos
What you’re looking at are long, beautifully coiled outer segments of rod #photoreceptors… basically the retina showing off its inner spaghetti aesthetic.
Elegant, tangled, and absolutely essential for seeing in low light.
One year since my paper “AAV-mediated transduction of songbird retina” was published in Frontiers in Physiology. It’s been great to see it reach ~3,400 views and ~740 downloads across a global audience.
Really grateful to everyone involved in this work. www.frontiersin.org/journals/phy...
Although the world outside still feels grey and wintry, under the microscope the retina reveals a vibrant landscape of color.
For #FluorescenceFriday: a section of the avian retina showing beautifully organized neuronal layers from inner to outer retina.

A glimpse into the beautifully layered architecture of the zebra finch retina highlighting the remarkable stratification of retinal cells and circuits from two different perspectives:
