@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 🧵

@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 🧵
