The findings offer reassurance to women using birth control, as the study found no increased risk across pills, IUDs, or implants.Read More
FeaturedNeuroscienceVisual Neuroscience·March 25, 2026·9 min readHow the Primary Visual Cortex Computes the “Gist” of a SceneResearchers have shown that the primary visual cortex (V1) computes statistical summaries of complex motion, such as mean and variance. This "ensemble perception" starts early in the visual hierarchy, allowing the brain to rapidly grasp the gist of a scene.Read More
