👁️ Can your eyes respond to an illusion as if it were real? Researchers found that pupil size and eye movements changed on if people saw a hole or a bump. The eyes responded to the perceived 3D shape — even though the stimulus was completely flat. 🌀 Read more: doi.org/10.1177/0301...

Larger tiles indicate that the measure has been used a higher number of times; the many smaller tiles show fragmentation.

Curious how tiny eye movements shape the visual input? Our new paper integrates spatiotemporal encoding into the standard model of #earlyvision. We suggest that models may be biased towards purely spatial perspectives—inviting us to rethink our view on early visual mechanisms doi.org/10.1167/jov....

Adding substantially more data clarified why monocular deprivation (MD) impairs depth discrimination. Surprisingly, degraded cortical maps did not reduce disparity selectivity. Instead, neurons representing central vision showed much lower trial-to-trial reliability in MD mice.
