Sebastiaan Mathôt@olafdimigen #Pupil #retina #visual I think this is an important new finding, which matches (and was inspired by) recent mouse studies: https://www.nature.com/articles/s41467-025-62736-4 4/4 🧵
Pupil size modulation drives retinal activity in mice and shapes human perception - Nature Communications
The pupil is known to assist retinal adaptation to light level changes. Here, the authors find a mechanism for how the pupillary light reflex drives monocular and binocular retinal activity in mice and shapes conscious visual perception in humans.
@olafdimigen #Pupil #retina #visual We observed a similar (but weaker) constriction-locked response later over visual cortex. Given these findings, an important open question is how the visual system maintains brightness constancy despite pupil-induced retinal and cortical activity. 3/4 🧵
@olafdimigen #Pupil #retina #visual Participants viewed flashes, triggering an initial burst of retinal activity followed by pupil constriction. We then used trial-to-trial variability in constriction latency to reveal a previously unknown retinal response that is locked to pupil constriction, rather than to visual stimulation. 2/4 🧵
❤️🔥 Exciting new preprint ❤️🔥 #Pupil constriction causes, by itself and independently of visual stimulation, activity in the human #retina and #visual system. w/ @olafdimigen 1/4 🧵

Les puces M4 et M5 sont limitées pour ceux qui veulent du Retina en (très) haute définition
Un développeur, Sam McLeod, vient de pointer un drôle de problème : pour les amateurs de haute définition (et de grands moniteurs), les puces M4 et M5 sont moins efficaces que les puces M2 et M3. C'est un problème dans un cas assez précis : si vous...
