Most vision scientists would bet that single-cone receptive fields exist in primate fovea, but it was not proven until now. It took years of sweat and $ to combine #AOSLO and electrophysiology. Congrats to PhD student Keaton Ramsey and his mentor Lawrence Sincich. www.nature.com/articles/s41...

Physiological basis of resolution acuity in vision - Nature Communications

Neural mechanisms underlying high visual acuity are not fully understood. Here the authors show that high resolution visual information is transmitted from the retina to the brain by neurons in t...

We can image single ganglion cells in the human eye with 3D OCT. But what happens if we focus the full 100 kHz scanning beam on a single cell—cone or ganglion?

Teresa Puthussery, a UC Berkeley vision scientist whose insights into the retina could one day help those with vision loss regain their sight, has been named a 2025 MacArthur “genius” Fellow. news.berkeley.edu/2025/10/08/v...

Congratulations @leahgjohnston.bsky.social for winning the @optica-fvm.bsky.social YIA! Most #visionscience folks know that stabilized retinal images fade. Fewer know that stabilized, but flickering, images also fade. Even fewer know that the flicker-fading doesn't take place in the retina.

Congrats to this year’s Young Investigator Award winners #OpticaFVM! 🎉 Leah Johnston "Profound perceptual fading of stabilized flicker cannot be accounted for by RGC desensitization" Joseph Emerson "Different contextual modulation mechanisms exhibit distinct laminar profiles in human V1"

Austin Roorda @roordalab.bsky.social delivering the richly deserved Boynton Lecture @optica-fvm.bsky.social @optica.org A tremendous journey with an incredible cast of characters that brought the world high resolution retinal imaging, Oz Vision and olo

👁️🔬 Excited to welcome Austin Roorda (@roordalab.bsky.social) as the 2025 Boynton Lecturer at Optica FVM! A pioneer in adaptive optics and retinal imaging, his work has reshaped how we see the eye—and how the eye sees. 🎤 Join us Oct 2–5 at UMN 🔗 www.opticafallvisionmeeting.org

Novel color via stimulation of individual photoreceptors at population scale

Image display by cell-by-cell retina stimulation, enabling colors impossible to see under natural viewing.

Such an honor for me to receive this award named after Bob Boynton, who I never knew, but whose approach to science was an inspiration for me. His son just happened to attending #VSS2025 when the award was announced. The apple does not fall far from the tree.
