Brain Activity Predicts Risky Choices Half a Second Before They Are Made

Summary: By recording directly from electrodes implanted in the human orbitofrontal cortex, neuroscientists discovered two neighboring circuits locked in a millisecond-by-millisecond “tug-of-war” between taking a risk and playing it safe.…

Brain Cells That Thrive on Uncertainty Help Us Adapt and Learn

Summary: Scientists have discovered a group of brain cells in the orbitofrontal cortex that become more active when outcomes are uncertain, revealing how the brain adapts and learns from unpredictable…
