Summary: Using a minimal mathematical rate model of the primary visual cortex, computational neuroscientists found that two intrinsic feedback mechanisms—rapid inhibition and homeostatic regulation—can constrain chaos and slash neural variability…

AI Models Predict New Vision Mechanisms in Real Brains
Summary: For decades, neuroscience textbooks have taught that the first stage of visual processing relies on two types of cells specialized in detecting “edges”—sharp transitions between light and dark. However,…
Promise of Reward Changes How We Pay Attention
Summary: A new study reveals that our brains treat sensitivity and decision bias as separate processes when rewards are at stake. Using eye-tracking and EEG during a visual task, researchers…
